Also, I'm the person in the video you posted. Please let me how I "tripped up."
In the interview you didn't answer the question posed. Could you please answer it now?
"A typical digital camera captures one image. Isn't what you're doing, in a sense, capturing a thousand different images with each image?"
Am I wrong in assuming that there is a matrix of 9 images which is repeated across the sensor? It was my impression that each microlens was superimposed over a 10x10 array of pixels, such that the entire matrix covered a 30x30 pixel area, and there are 108x108 microlens arrays, for a total of 104,976 microlenses?
I admit that I was wrong in my choice of words concerning focal length. I meant that within each matrix of 9 microlenses, one of them doesn't bend the light, while 4 of them bring items closer than the unbent light into focus, and the other 4 bring farther items into focus.
With that, your software creates 9 different images that focus on light coming from objects 9 different distances from your camera. Is that correct?
I never said there were only 9 microlenses. In my original post I said there was a repeated array of 9 microlenses. Each type of microlens is processed into one 'layer'. Is that wrong?
