It is possible to change, and the initial shipping value varies by product, but is approximately 340MB/s ~ 360MB/s. (However, the initial shipment value is notified

(subject to change without)

4.1.2 Device Temperature

This function monitors the current temperature of the parts selected in ‘Device Temperature Selector’. ‘Temperature

As soon as you execute ‘Update Selector’, temperature information is returned as a Celsius (℃) value including decimal points. some

The model can monitor the temperature of the image sensor and the temperature of the FPGA Core board.

4.1.3 Device Temperature State

The internal temperature of the camera is monitored and displayed as ‘Normal’, ‘Warning’, or ‘Critical’. Each state

What this means is described in more detail in Section 4-18 ‘Device Temperature State’.

4.1.4 Device Reset

Hard-Reset allows you to re-power the camera with a command. USB connection is established immediately after entering the command.

At the same time as it is removed, the camera's power is re-applied and rebooted. Therefore, after Device Reset, in Application

The camera must be opened again for normal use.

4.1.5 Device Sleep Mode

This function allows you to reduce total power consumption by changing the camera's state to sleep mode. When setting Soft Sleep, this

The image sensor goes to sleep, and when set to Deep Sleep mode, the image sensor and FPGA also go to sleep. gun

Power consumption can be reduced by up to 80%. When switching from Deep Sleep to Disable (Normal), approx.

An initialization time of 1.4Sec to 2Sec is required.

4.2 Image Format Control

This is a function that allows you to change the settings for the camera's image output size and format.

4.2.1 ROI (Region Of Interest)

By setting Width, Height, Offset

As the output image size gets smaller, the frame rate increases. (However, MU-A121R(L)-31 model and MU-

(Excluding ADC 12bit mode of A201R(L)-18 model)

※ Note

1) Frame Rate changed due to ROI can be checked through the ‘Resulting Frame Rate’ parameter.

4.2.2 Decimation Horizontal / Vertical

This is a function that reads from the image sensor in vertical or horizontal directions, skipping 1-pixel at a time. resolution of the image

is reduced by half, while the Frame Rate increases. For color models, all four color channels are displayed.

In order to do this, it will be skipped in 2-pixel units.

Decimation Hor. = 1x

Decimation Hor. = 1x

Decimation Hor. = 2x

Decimation Vert. = 1x

Decimation Vert. = 2x

Decimation Vert. = 1x

※ Note

The frame rate changed due to decimation can be checked through the ‘Resulting Frame Rate’ parameter.

4.2.3 Binning Horizontal / Vertical (MU-A160M-226 and MU-A320M-118 models only)

This is a function that accumulates and reads pixel values 1-pixel at a time from the image sensor in the vertical or horizontal direction. This

The resolution of the unknown is halved while the Frame Rate is increased or the brightness is approximately doubled. Color

In the case of Dell, calculations are performed in 2-pixel units to express all four color channels.

Binning Hor. = 1x

Binning Hor. = 1x

Binning Hor. = 2x

Binning Vert. = 1x

Binning Vert. = 2x

Binning Vert. = 1x

※ Note

The frame rate changed due to binning can be checked through the ‘Resulting Frame Rate’ parameter.

4.2.4 Reverse X, Y

This is a function that reverses the left/right or top/bottom of the video and outputs it. For color models, select ‘Reverse Mode’

Accordingly, the image is output with the ‘Bayer Pixel Order’ also changed.

1) When Reverse (Bayer RG → Bayer GR)

2) When Reverse Y mode is set to True, the top/bottom of the video is reversed. (Bayer RG → Bayer GB)

※ Precautions

1) When 'Reverse Y' is selected, defective pixels may appear because the use of Defect Filter is limited. Because of this

Exposed defective pixels can be removed in the ‘Defect Pixel Correction’ category. (Section ‘Defect Pixel Correction’

Note)

2) When ROI and Reverse are used simultaneously, the ROI function is applied from the reversed image. Same as the picture below

When Reverse is activated, the position of (0,0) Pixel, which is the starting coordinate of the Image, is reversed. Because of this Reverse

In order to image the same area as before application, an Image Offset equal to Total Size - ROI Size is required.

* Ramp size may vary depending on pixel format.

※ When 8bit is set: Ramp Size = 256 Pixel

※ When setting 10bit: Ramp Size = 1024 Pixel

※ When 12bit is set: Ramp Size = 4096 Pixel

4.3 Acquisition Control

This is a function that allows you to set the method of acquiring images from the camera. Define the number of image frames to acquire.

You can.

1) Single Frame

Each time the ‘Acquisition Start’ command is input, one image is captured and transmitted. Just one image

Acquisition stops automatically after transmission, so a separate ‘Acquisition Stop’ command is not required.

If ‘Trigger Mode’ is ‘On’, the light is exposed and transmitted by the trigger. Trigger Mode is ‘Off’

In this case, it is possible to acquire and transmit a new image with just the ‘Acquisition Start’ command.

2) Multi Frame & Acquisition Frame Count

Each time the ‘Acquisition Start’ command is input, images are captured as defined in ‘Acquisition Frame Count’

and send it. Acquisition automatically stops after transmitting the specified number of images, so separate

The ‘Acquisition Stop’ command is not required. However, if the ‘Acquisition Stop’ command is entered during Grab,

Right, it reads out and transmits the frame being exposed and then stops. If ‘Trigger Mode’ is ‘On’,

It is exposed and transmitted by a power trigger.

3) Continuous

Images are captured at the cycle defined in ‘Acquisition Frame Rate’ from the time the ‘Acquisition Start’ command is input.

Capture and transmit. When the ‘Acquisition Stop’ command is entered during Grab, up to the currently exposed image

After readout and transmission, acquisition will stop. At the end of exposure, the ‘Acquisition Stop’ command is issued.

Once entered, Acquisition ends after the ongoing Readout is completed. If ‘Trigger Mode’ is ‘On’

In this case, it is exposed and transmitted by a trigger.

4.4 Trigger Mode Control

Controls image acquisition and output timing. The main method of image acquisition is external synchronization (Trigger Mode = On).

and internal synchronization (Trigger Mode = Off, Freerun Mode) modes, and you can set acquisition delay or transmission delay, etc.

You can.

<Timing Diagram of Trigger Signals>

* Hardware Delay

※ When using Opto-isolated Input, set ‘Line Inverter’ to ‘False’ (Rising of Trigger signal) for shorter delay.

It is advantageous to shoot from the edge. If faster performance is required, input via the GPI port is recommended.

※ The delay time measured above is based on a trigger signal input of 3.3V level, and the delay time at a higher signal level may vary.

You can.

4.4.1 Trigger Mode

‘Trigger Mode’ is a function that controls the exposure method of the image sensor. When setting ‘Trigger Mode’ to ‘Off’

Right, the camera operates in Freerun Mode. Freerun mode is the maximum that can operate with the current settings.

Internal VD is created based on Frame Rate. At the same time, an exposure signal is generated as much as the set ‘Exposure Time’

and is input to the image sensor. Periodic exposure is performed by the generated Exposure signal, and exposure is performed accordingly.

After reading the published image, it is transmitted to the host.

<Timing Diagram of Freerun Mode>

On the other hand, if Trigger Mode is set to ‘On’, the camera operates in Trigger Mode. Trigger

In mode, the exposure start point or exposure time is determined by the trigger input from the outside. Exposure

After completion, frames are read and transmitted in the same way as in Freerun mode. Detailed timing

Please refer to the picture on p.21<Timing Diagram of Trigger Signals>.

※ Precautions

1) If a trigger signal with a cycle faster than the product’s maximum frame rate is input, the frame rate of the output image is

It deteriorates. (For determination of abnormal trigger input, refer to ‘Counter Control’) Therefore, signal specifications within camera specifications must be met.

Please follow the instructions and enter your information.

2) If noise enters the trigger signal line, there is a possibility that the camera may mistake the noise for a trigger signal.

c. (Refer to the ‘Line Debouncer Time’ function related to noise filtering)

3) When switching the trigger mode from On to Off during acquisition, a defective image may occur due to over trigger.

This may occur in the same form as an increase in Undelivered Frames. Therefore, when the trigger signal is stopped and readout occurs,

It is advisable to switch modes after a time sleep of approximately 1/Frame Rate second. Same

Since defective images may occur for the same reason when switching from Off to On,

Time Sleep is required.

<Timing Diagram of Trigger Mode Changing>

4.4.2 Trigger Source

Define the source of the trigger signal. Applies when Trigger Mode is set to On.

▶Hardware trigger = 6 pin connector input

• Line1: Trigger input is received through pin 2 (Trigger +) and pin 5 (Trigger -). Voltage of trigger signal

The level range is from a minimum of 2.5V to a maximum of 24V.

• Line2, Line3: Trigger input is received through pin 3 (GPIO1) or pin 4 (GPIO2).

▶ Software trigger = Enter Host Software Trigger Command

Create a trigger inside the camera through the Software Trigger function. In this setting, ‘Exposure Mode’ is

Only ‘Timed’ shutter mode is supported.

※ Note

If you set ‘Counter Selector’ in the ‘Counter And Timer Control’ category to ‘Line Trigger’, the input from the camera will be triggered.

The total number of valid triggers is returned as ‘Counter Value’. This counter is initialized to 0 by Streaming Start.

It works.

4.4.3 Trigger Delay

The trigger is delayed inside the camera by the time set in ‘Trigger Delay’ from the time of trigger input.

This is a function that sets it to work. If ‘Trigger Delay’ is set to a value other than 0, the trigger signal is delayed.

If a new trigger signal is input during the process, the delay for the existing trigger signal continues and the new trigger is

It will be ignored. In other words, if the delay time is greater than the trigger period, the frame rate may decrease due to missing trigger.

You can. For detailed timing diagram, please refer to the diagram on P.21<Timing Diagram of Trigger Signals>.

c.

4.4.4 Transfer Delay

At the stage of transmitting the image that has completed image pre-processing inside the camera, the image packet is

This function delays the start of transmission. When multiple camera videos are input from a single host, input

You can adjust the timing to distribute input points. Since the input value of the parameter is in Clock units, it is expressed as time.

Please refer to the formula below for conversion.

𝑇𝑟𝑎𝑛𝑠𝑓𝑒𝑟 𝐷𝑒𝑙𝑎𝑦(𝑛𝑠) = 𝑇𝑟𝑎𝑛𝑠𝑓𝑒𝑟 𝐷𝑒𝑙𝑎𝑦 𝑉𝑎𝑙𝑢𝑒 × 10𝑛𝑠

※ Note

1) This can only be set when the ‘Low-latency Mode Enable’ parameter is set to ‘False’.

2) For more detailed timing, please refer to the ‘Low-Latency Mode’ section.

4.5 Exposure Control

4.5.1 Exposure mode

This function allows the camera to select the exposure method. If ‘Trigger Source’ is set to ‘Line1’, ‘Timed’

and ‘Trigger Width’ can be set respectively. However, if ‘Trigger Source’ is set to ‘Software’

It only works with ‘Timed’ shutter.

In the ‘Timed’ shutter method, exposure occurs only for the time set in ‘Exposure Time’. The trigger is just

It serves to specify the starting point of exposure. On the other hand, the ‘Trigger Width’ shutter method uses the pulse of the trigger signal

The width becomes the effective exposure time.

<Timing Diagram of Pulse Width Trigger>

4.5.2 Exposure Time

Set the camera exposure time. This time only applies when ‘Exposure Mode is set to ‘Timed’.

Applies. In Freerun Mode, if the Exposure Time is longer than the Frame Period, the Frame Rate

It will decrease.

The actual exposure signal inside the camera is generated by the ‘HD’ timer. This ‘HD’ timer has a horizontal

Because it is related to Readout Size, generally the smaller the Image Width, the longer the period of the HD signal.

It will be shortened. Also, parameters related to video transmission bandwidth (ex. Pixel Format, Device Link Througput Limit

etc.), the period of the HD signal also changes.

※ Note

Set ‘Counter Selector’ in the ‘Counter And Timer Control’ category to ‘Exposure Start’ or ‘Exposure End’

Once set, the camera will return the start and end exposure counts as ‘Counter Value’. This counter is Streaming

It is initialized to 0 by Start.

※ Precautions

1) In MU-AxxxM(K) series cameras, there is an error between Exposure Time and actual exposure time. below

The time specified in the table is an absolute time, and when exposing each frame, additional exposure time other than Exposure Time is required.

It's time.

2) Exposure start (and exposure end) may be delayed from the time the trigger signal reaches the camera.

There is. (Excluding hardware delay and ‘Line Debouncer Time’)

※ The above 1HD time is based on the case of outputting the maximum frame rate under the maximum image size condition.

4.4.3 Sensor Shutter Mode (MU-A121R/L-31 and MU-A201R/L-18 models only)

‘Sensor Shutter Mode’ can be changed only for the two product groups that adopt Rolling Shutter-based image sensors.

There is. Basically, ‘Rolling shutter’ mode is supported, but if the subject moves quickly, the time difference may occur.

Image distortion may appear. On the other hand, because overlap is possible, the maximum frame rate of the product can be reached.

You can. It has the advantage of having uniform exposure time for all lines.

If you use the ‘Global Reset’ mode, which resets each line of the image at the same time, image distortion due to time difference is avoided.

It disappears. However, since all lines are exposed immediately after reset, the more you read in the vertical direction, the more

Exposure time becomes longer. And because Overlapping triggers are not supported, the Frame Rate is approximately

It can be reduced to less than half.

※ Precautions

Proper Exposure Flash timing in ‘Rolling’ mode requires that the first and last lines are in common.

This is the time between exposures. Only then can the entire image line be uniformly illuminated.

4.5.4 Exposure Auto

This is a function that allows the camera to automatically adjust ‘Exposure Time’ to maintain the desired brightness.

Can be set when ‘ExposureMode’ is set to ‘Timed’. And ‘Auto Exposure Time Lower’

‘Exposure Time’ changes only in the time between ‘Limit’ and ‘Auto Exposure Time Upper Limit’.

※ Precautions

1) If the Exposure Time is too short, a flickering image may be output due to flickering of lights, etc.

2) If ‘Exposure Time’ becomes longer than Frame Time to reach maximum brightness, Frame Rate

It may deteriorate.

4.6 Digital I/O Control

This function allows you to set camera external I/O signals. The input/output direction of each I/O is fixed, and the I/O

You can change the logical specifications of signals through a port.

<Line Block Diagram>

4.6.1 Line Debouncer

This is a function to remove (debouncing) chattering noise from the camera's external trigger line. ‘Line Debouncer

Only signals that maintain the state for the time set in ‘Time’ are accepted as valid inputs. Line Debouncer

Since the Timer checks the state transition of the Trigger Line, the delay is delayed by the time set in ‘Line Debouncer Timer’.

You will receive a trigger input.

<Timing Diagram of Line Debouncer>

4.7 Timer Control

Timer Control allows you to change the settings of the strobe signal output outside the camera. ‘Trigger

When ‘Mode’ is Off (Freerun Mode), the time of generation of Timer Flash signal is set to exposure start or ‘Internal VD’.

You can select the ‘Start’ point. (Refer to the diagram <Timing Diagram of Freerun Mode>) When VD is initialized

Since the viewpoint is ahead of the shutter operation point, ‘Timer Delay’ is required to synchronize with the lighting.

You can do it.

On the other hand, when ‘Trigger Mode’ is On, the exposure start point or trigger signal detection point (state transition point) is determined.

You can select it as the Timer Flash creation location. If a Timer is created by an external trigger, set ‘Timer Delay’

This allows you to synchronize with the actual exposure section. (Refer to the <Timing Diagram of Trigger Signals> diagram)

As mentioned in ‘Exposure Control’ in Section 4.5, the trigger signal input to the camera and the actual signal to the image sensor

There is a certain time delay until exposure. This delay time (Exposure Start Delay) is ‘Timer Trigger Source’.

When set to ‘Exposure Start’, a negative value ‘Timer Delay’ can also be used. negative number

If you enter a signed real number value into ‘Timer Delay’, it will delay up to 3HD hours from the actual exposure time to the sensor.

The timer signal generation time can be advanced. (Refer to the <Timing Diagram of Timer Control> diagram)

<Timing Diagram of Timer Control>

4.8 Counter Control

The series of processes in which the camera receives trigger input, exposes, and transmits images can be monitored with a step-by-step counter.

This is a feature that can be used. Additionally, signal input that exceeds the camera specifications, such as trigger input with a cycle faster than the frame speed.

You can also check the power.

4.9 Chunk Data Control

Chunk data is tagged data that can be grouped within blocks of data to transmit metadata.

This is a data block. Each chunk consists of chunk data and a trailing tag, and the tag contains a ‘unique chunk identifier.

(Unique Chunk Identifier, CID)’ and ‘Chunk data length’. This Chunk Data is USB3Vision

Transmitted in accordance with Standard 1.1.

Chunk data is sent along with the last payload packet of the image. Unique chunk identifier for each chunk

Please refer to the table below for (Unique Chunk Identifier, CID) and data size information.

4.10 Event Control

Event notification is a function that sends an event packet from the camera to the host in each specific event situation. image

Event Packet is transmitted through a channel different from the transmission channel.

Events occur in cameras in real time, but if packet transmission delays occur due to host circumstances, Event

There is also a possibility that the actual receipt of the packet may be delayed or missed. Up to 128 inside the camera

Events can be loaded, but if transmission is delayed any longer, newly generated events will be missed.

4.11 Analog Control

You can change the analog and digital characteristics of the video signal. Mainly changing properties for image pixels

The functions you can do are listed.

<Block Diagram of Analog Control>

4.11.1 Gain, Gain Auto

While Gain can change the sensitivity of the image without deteriorating the frame rate, it also reduces image noise.

may increase. The gain of the camera is composed of Analog Gain and Digital Gain respectively, and ‘Gain

You can select through ‘Selector’.

Gain Auto is a function that automatically adjusts the gain value to the target brightness by the Auto Gain Control algorithm.

The range of gain values that change while Gain Auto is running is ‘Auto Gain Lower Limit’ and ‘Auto Gain Upper’.

Limited by ‘Limit’.

※ Precautions

Priority for brightness changes when ‘Gain Auto’ is used simultaneously with the ‘Exposure Auto’ function

▶ When the brightness becomes brighter: Exposure Time increases first, and Gain increases when the limit is reached.

▶ When brightness becomes dark: Gain decreases first, and Exposure Time decreases when the limit is reached.

4.11.2 Black Level

‘Black Level’ is a function that allows you to set the offset of the camera’s sensitivity. ‘Black Level’ is about Gain and Ma.

Likewise, it is composed of Analog Black Level and Digital Black Level, and can be adjusted through ‘Black Level Selector’.

You can choose.

4.11.3 Gamma

This function is used to adjust Gamma Correction. You can correct the contrast of camera images.

<ITE ‘GrayScale ChartⅡ (y=0.45)’>

※ Precautions

• The Gamma Correction function cannot be used simultaneously with LUT. When activating LUT and Gamma simultaneously

Right, the function activated first is automatically disabled.

4.11.4 Pattern Noise Removal (MU-A121R/L-31 and MU-A201R/L-18 models only)

This feature can be improved when noise similar to a mosaic pattern appears in the image. user's

Sensitivity imbalance between mosaic patterns or specific color channels after setup for the environment (lighting, lenses, etc.) is completed.

If this phenomenon occurs, you can self-correct it. Immediate correction through ‘Pattern Noise Removal’ command

It is possible.

※ Precautions

1) To perform ‘Pattern Noise Removal’, you must grab the image.

2) After correcting the video by entering a command, you must save the correction value to the camera using the ‘Userset Save’ command.

I do.

4.11.5 Noise Reduction Filter

This function allows you to reduce video noise through a noise filter. When activated, it is reflected from the next frame.

The sharpness of the video may deteriorate somewhat.

4.12 Balance Ratio Control

This function is used to correct the color balance of color cameras. To achieve a balance of sensitivity between color channels to the light source,

Correct it. If the color temperature of the light source changes, new calibration is required.

※ Precautions

1) Pixels outside of a certain brightness range are judged as noise. Also, even if there is a strong bias toward a specific color,

Excluded from Auto White Balance calculation. Please refer to the criteria below for detailed conditions.

1. |R-Y| < 160DN

2. |B-Y| < 160DN

3. -160DN < (B-Y) + (R-Y) < 160DN

2) After color correction, the correction value must be saved in the camera’s PROM using the ‘Userset Save’ Command.

4.13 User Set Control

This function is used to save or load the values of parameters set by the user. Always change during Grab.

Since there are parameters that should not be changed, Userset Load is performed in Acquisition Stop state.

I recommend doing so.

4.14 LUT Control

The LUT (Look Up Table) function matches the digitally converted pixel value to the table 1:1 with the input value and output value.

This is a conversion function. Pixel value is determined by the LUT Value (Output Image) defined for each Index (Input Image) in the table.

It will be replaced. For color models, the luminance component is loaded into the LUT memory.

Ex) If you use a table with values in the form y=2x, low-light pixels can see an improvement in sensitivity, while high-light pixels can see an improvement in sensitivity.

Pixels become saturated, resulting in loss of dynamic range.

※ Precautions

• The LUT function cannot be used simultaneously with Gamma Control. When activating LUT and Gamma simultaneously,

The function activated first is automatically disabled.

4.15 Defect Pixel Correction

This function allows you to manage the camera’s defect pixels. Compensation for defective pixels when the product is shipped from the factory

This is done. However, the user can additionally define and correct pixels that he or she considers to be bad pixels.

Yes. Up to 128 dead pixels for each camera can be stored in Flash PROM.

※ Precautions

• After correction, you must enter the ‘Userset Save’ command to save it to the camera.

Ex) When 20 defect pixels are corrected at factory shipment, the user defines two additional pixels.

Factory Defined

4.16 Low-Latency Mode

Image data pre-processed in FPGA is applied to an Image Buffer (Frame Buffer) of approximately 512MB.

You can select the loading method. The initial value is ‘Low-latency Mode Enable’ is ‘True’.

This is a method of transmitting images as soon as the Packet Size is entered into the Buffer. On the other hand, ‘Low-latency

If ‘Mode Enable’ is set to ‘False’, it becomes ‘Full-Block Mode’ and all image frames are

Transmission must be buffered.

The time and timing for imaging, readout, and preprocessing are the same for both modes, but transmission to the host is the same.

The starting timing is different. In other words, there is a difference in the total time from trigger input to host reception.

Yes.

<Timing Diagram of ‘Low-Latency Mode’>

<Timing Diagram of ‘Full-Block Mode’>

If the host needs to receive video from multiple cameras, the best way is to set up a dedicated port for each port.

It uses a multi-port host card with chipset attached. If not, each camera

Packet transmission must be distributed so as not to exceed the maximum bandwidth of the host (receiver). For example

In contrast, by applying different ‘Transfer Delay’ in ‘Full-Block Mode’, the image transmission time can be distributed.

Yes. In this case, the host receives images sequentially.

※ Precautions

1) The ‘Low-latency Mode Enable’ parameter is applied immediately when changed. However, it must be changed when Acquisition Stops.

Yes.

2) The ‘Transfer Delay’ function can only be set when ‘Low-latency Mode Enable’ is ‘False’.

3) If the host PC consumes a lot of CPU resources due to image processing, etc., camera transmission may also be affected.

Yes.

4.17 Color Transformation Control

Color Transformation is a matrix that can apply gain and offset to each R, G, and B channel.

This function is used for color correction when the pixel value output from the image sensor differs from the actual product.

c. For each R, G, and B channel, the parts with insufficient sensitivity are multiplied or added, and the parts with excess sensitivity are divided or added.

You can take it out. Additionally, it can be reproduced by applying pre-defined matrix values that meet some color standards.

There is also.

4.18 Device Temperature State

The temperature status of MU-AxxxM(K) series products is divided into three stages in the ‘Device Temperature State’ parameter.

Uh, we provide. When you press the ‘Temperature Update Feature’ command, the ‘Device Temperature State’ value is immediately changed.

It returns.

‘Normal’ means a stable temperature. All elements of the camera are operating smoothly.

c. ‘Warning’ indicates that the product’s heat generation is somewhat high. The moment it exceeds the reference temperature of 𝑇𝑡ℎ𝑟1

Generates a ‘Device Temperature Warning’ Event to notify the host of changes in ‘Device Temperature State’

(If Event is set. Refer to Section 4.10 Event Control.) Image acquisition is possible, but through heat dissipation.

This situation requires lowering the temperature of the camera.

If the product temperature continues to increase, the moment it reaches the second threshold temperature, 𝑇𝑡ℎ𝑟2, ‘Device

A ‘Temperature Critical’ Event occurs. (If the Event is set. Refer to Section 4.10 Event Control.)

At this time, heat dissipation occurs on its own to protect the product itself. Camera Acquisition

If in the Enable state, the readout of the image sensor is arbitrarily stopped and the test moves to the left at the same time.

Outputs the pattern image in trigger asynchronous mode.

Image Data of Device Temperature Critical State

If the temperature of the product decreases due to the camera's own heat dissipation operation or external heat dissipation measures,

‘Device Temperature State’ is also updated. It becomes more than 4℃ lower than the standard temperature of ‘Critical’ state, 𝑇𝑡ℎ𝑟2.

If so, the status changes to ‘Warning’. In this case, the image data that was replaced with the Test Pattern has already been
