Color blindness or color vision deficiency is the decreased ability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of some eye, nerve, or brain damage, or exposure to certainchemicals.
Color Blindness has different variants, on the basis of the colors a person is unable to see: Like close to 6% of males, suffer from anomalous trichromacy, also known as red-green colorblindness. In simple the person can’t tell the difference between some shades of red, green, and brown apart. One example: red and brown look (depending on the light) almost exactly alike.
Now lets talk about the topic,
A security researcher Dan Kaminsky is attempting to develop a fix for faulty photoreceptors in one's eyes. With an iPhone application. Dan is developing an iPhone app that is capable of processing images to fix them for those (or make them suitable for those) who have colorblindness.
How the App works: The iPhone's camera will feed in images to the display in real time, but in between that, the images will be tweaked; courtesy to a collection of changeable color-shifting schemes from which the user can choose.
What is the technique:Exaggeration. Some colors will be exagerated to the extent that they over shadow the inability to view said colors. For example, the most basic Hue Quantize will exaggerate both red and green and moves them further to the extremes of the color spectrum, away from the indistinguishable middle ground where colorblind users usually focus.
Price and Availability: Named The DanKam app will retail for $3 in the iTunes app store and Android Marketplace. In due time BlackBerry, Windows Phone 7 and Nokia handsets versions for the app will also be rolled out. --------
