i have developed a app that convert color to sound, is it useful?
Is it useful? i want to convert a picture to sound. The app just convert a pixel of a image to sound , and you can move your finger to pick pixel. it requried ios5 or later .
It just take a screenshoot of the imageview , and scale the image in half. And it picks 16 pixels around the finger , and convet the pixel color th HSV, use the H S V compont to adjust 3 sine wav of different frequncy.
i find it is hard to use for me .but fun to use.
Thank you for your useful information. I have read the web site very carefully . There is a interest article that can find a pixels distance from camera .http://www.seeingwithsound.com/extra/AV-eng.pdf ,This is important to visual impaired . The theory . A camera has a focus , or depth of field .http://en.wikipedia.org/wiki/Depth_of_fieldhttp://en.wikipedia.org/wiki/Depth_of_field,that is when a camera is focus at near objects , the pixels of far objects will blur or unclear .
The iPhone can auto adjust the focus, but there isn't a public API to get the distance .
I have a tip to find near object . The objects nearby has continues long edge , the background objects's edge isn't,becuase they are blocked by nearby objects.
happy new year.
