How do I solve the issue of Simulink's prescan color display block with only black screen?

I'm using Siemens Prescan and Simulink.

While using the Ground Truth sensor, there was a problem because only the black screen, not the camera image, appeared in the simulink color display block.

I checked the camera sensor data value with bus selector and display and it seems to measure the data value normally, but the color display only shows the black screen.

I would appreciate it if you could tell me how to solve it.

I notice a red streak on the image display. red streaks cannot occur on grayscale images converted to rgb.

I wonder about the data type of the r g b components, and about their value range.

Please let me know the data type of the rgb component and how to find its range of values. Thank you

See https://www.mathworks.com/help/simulink/ug/displaying-signal-properties.html to display the port data types.

For the range, you might need to put couple of minmax blocks https://www.mathworks.com/help/simulink/slref/minmax.html on and send the output to Display blocks https://www.mathworks.com/help/simulink/slref/display.html .

Thank you.

Data type is 'uint8' all rgb components.

and its range of value is the (min)-inf, (max)inf.

i think that's where the problem occurred.

Additionally, the scene you are looking at with the camera sensor is like the picture. Attached is the picture for smooth understanding.

All objects are just stationary.(not move)

uint8 is restricted to the range 0 to 255, so I do not understand how the -inf to +inf was found?
