  1. Images to Audio By Donna Jones

  2. Outline • Image Input • Mathematical Calculations • Audio Output

  3. Image Input • Take an image that is sent to the Blackfin’s memory • Find its red, green, and blue values • red = (rmask & imgInput[0]) >> 10; • green = (gmask & imgInput[0]) >> 5; • blue = bmask & imgInput[0];

  4. Mathematical Calculations • Find frequency of the lightwave and then map it to sound frequency • Use these values in conjuction with the RGB values from the image • Use: r = 2*3.14*(fsr/FS)*(t+1); • g = 2*3.14*(fsg/FS)*(t+1); • b = 2*3.14*(fsb/FS)*(t+1); • output = ((red*10000)*sinf(r*t))+((green*10000)*sinf(g*t))+((blue*10000)*sinf(b*t));

  5. Audio Output • The audio is outputted from the formul • iChannel0LeftOut = indivOutput; • iChannel0RightOut = indivOutput;

  6. Issues • Can not compute an entire 64x64 image at once, there is a delay causing a popping sound • Final product only analyzes one pixel, but could maybe be expanded to an entire picture if given more time
