How much our eyes can see if considered in pixel, in the frame of 20cm x 20cm

Our pixel resolution is dependent on the number of receptor cells, which varies with age and between individuals. Hawks have much higher resolution, but our advantage is that we don't bother much with these receptor "pixels." Our receptor cells cannot be considered like digital pixels because their threshold of intensity and wavelength is an analog continuum, and because we have a much bigger, analog, massive parallel processing system controlling and filtering their input.
If you get an exact amount of cells per millimeter, that would be great, but don't bank on the idea that this would be a useful measure for a real human being. There is no way to compare a human retina with a digital device such as a CCD. Sorta like comparing a real apple with a drawing of an orange that came off of 300 dip laser printer...

in total,our eyes can see 1000000000(billion)gigabytes of infomation a second.
