Why does the white color appear darker when displaying a 10 bit image?
Why is the grayscale only 255 instead of 1024?
We checked the manual and found that the IMX8MQ chip supports 10 bit image output. Based on the IMX8MQ chip, we modified the kernel code to change the 8-bit color depth to 10 bits, and also modified the pixel_clock_frequency. We also light up the display, which looks like the following image "3400x1300x30 bit 60HZ".
But our original BMP image reading SD, according to ARGB, which means each pixel is 32 bits, can also be displayed normally on "3400x1300x30 bit 60HZ", and
a. The grayscale transition image has not reached 1024 levels, only 255 levels,
b. What could be the reason why the overall white screen appears darker when clicked? Please help analyze, thank you very much!
Hello,
In fact the variable is unsigned in so maximum is 255 the value of gray, this is the maximum value of gray.

HI,Is there a way to achieve 1024 level gray for IMX8?
