I want something like this, New ArduEye using Centeye Stonyman image sensors - YouTube (i find this today) this has a resolution 112 * 112, of which 14 blocks of 8x8, is more than enough for me.
The most importante is make arrays of blocks 8x8 pixeis. But i want something simple, and with libraries, because this part isn´t important for my work. I only want capture same intensities of gray, make my codification and print the result.
