**Self Build Images**
Please describe your issue below:
We are working on a application where we want to detect the color on the screen which is HDMI out from Khadas. We are using a black and white image where black color is in the left half and white color in the right half. The image resolution is 1920 x 1080. If we check the value of the pixel independently in windows system it is showing (0,0,0,) for Black and (255,255,255) for White which is expected and correct. But when we check the data of the same image through our firmware, the value we get for white are (8080eb in Hex) which in RGB format is (128,128,235) and for Black are (808010 in Hex) which in RGB format is (128,128,16) which is not the expected result. Ideally for white it should be somewhat near to (ebebeb) for white and (101010)for black.
To verify our assumption, we tried with another image with other colors and we did not get the correct RGB values of the image. We are using Khadas VIM3. Is there any parameter or setting which can affect the capability of Khadas VIM3 to correctly get RGB values of any image?
