CUD, Color Universal Design, is a design system for supporting people with various types of color vision. Simple CUD Camera application is a simple software which helps to see how color looks like for colorblind people.

2 types, Deuteranope and Protanope color filters are provided for this purpose, but please note these filters are for simple simulation, actual view may differ depending on each colorblind people. For most people, they see better color than this. Filters simulate very strong color blindness.

Camera preview is filtered realtime.

Images taken are saved under sdcard/DCIM/Camera/ with date_time filename. Width of image size is fixed to 800 for memory usage limitation. When save original option is selected, non-filtered image is also saved.

I've included daltonize algorithm, but not sure if it really works or not. Experimental, would be helpful if there's any feedback.

Hope this tool may help some people in the world.
