  The human visual color response is driven by specialized cells called cones,
which exist in three types, viz. R, G, and B. Software is developed to simulate
how color images are displayed for different types of color blindness.
Specified the default color deficiency associated with a user, it generates a
preview of the rainbow (in the visible range, from red to violet) and shows up,
side by side with a colorful image provided as input, the display correspondent
colorblind. The idea is to provide an image processing after image acquisition
to enable a better perception ofcolors by the color blind. Examples of
pseudo-correction are shown for the case of Protanopia (red blindness). The
system is adapted into a screen of an i-pad or a cellphone in which the
colorblind observe the camera, the image processed with color detail previously
imperceptible by his naked eye. As prospecting, wearable computer glasses could
be manufactured to provide a corrected image playback. The approach can also
provide augmented reality for human vision by adding the UV or IR responses as
a new feature of Google Glass.
