Colorblind Corrector with Augm

This app is intended to improve color perception for individuals with colorblindness by adjusting the screen colors. It attempts to do so while maintaining the natural coloring as much as possible. Although it is not possible to correct color blindness completely by optical means, the name was chosen to distinguish this approach from other programs that assist the color blind by providing color names, or by changing the difficult-to-perceive colors into completely different colors. The enhanced image will appear abnormal to those with normal color vision, but my hope is that this enhanced image, when seen through the eyes of the colorblind, will be more like what a person with normal color vision sees when looking at the unenhanced image. The amount of benefit for each colorblind individual depends on the particular genetics of that individual. I am interested to learn how much improvement is seen by each person, if any at all, so please let me know.Normal color perception requires 3 different kinds of retinal cones, each containing a photosensitive protein, distinguished by its response to frequencies of light. The most common forms of color blindness occur when one of these proteins is defective. The defective protein has a frequency response that is too similar to one of the normal proteins, which usually leads to reduced contrast in the red-green dimension. This app selectively adjusts the red-green contrast. The algorithm is thus based on how the eye processes color, rather than on the physics of the optical input.There are 2 interface screens, one for displaying the live camera image, and the other for displaying a still photograph image. One can move from the live view screen to the still image screen by pressing the shutter button in the lower right to save the live image (actually saves 2 images - one in original colors and one color-enhanced) or by pressing the gallery image in the lower left to select an image from the gallery. From the still image screen, one can return to the live view screen by pressing the "eye" button on the right.Tapping the screen will toggle on/off the Help hint boxes next to the icons and sliders.A new feature is Augmented Reality capability, using a Cardboard-type viewer device. This is reached by pressing the Viewer image button while in either the live view screen or the still image screen. It will create dual images for the viewer. Pressing the Viewer image again will return back to the full-screen image.There are 2 sliders that control the color adjustment. The bottom slider controls the amount of adjustment, with zero adjustment (therefore showing the unenhanced image) at far left, and maximum adjustment on the far right. It will make the reds redder, and the greens greener. The top slider is newly designed to mimic the principle behind the anomaloscope. People with anomalous color deficiency require either more red or more green light to be mixed together to equal yellow light. It provides more enhancement of red when the slider is to the left, and more enhancement of green when the slider is to the right. I find the pulse function is very helpful in setting the sliders. I suggest starting with the lower slider around mid-point, activating the pulse feature, and then adjusting the top slider to achieve the best effect. Then stop the pulse action to view the image.
