This app show three images with different color conversion at once to make it easier for the various types color blind people to distinguish colors.
Touch one of them to display that screen in full screen.
In full screen display, the description of the pixel color at the center of the screen is displayed at the top.
Touching the screen during full screen display pauses the camera display update.
I would be happy if this app is helpful for you.
If you have any idea of function to help more, please let me know about that. I will consider to realize that.
