Yeah, I've thought about that...and I don't know any definition of color
pixels that only includes one of the three colors...obviously, B&W is a
single value...but these cameras aren't monochrome... 24 bit color pixels
consist of one 8 bit value of each of the three colors... 36 bit of one 12
bit value of each of the three colors...and that's a LOT more data than you
get out of the sensor!
A 4k x 4k sensor, say at 8 bits/site (for sake of ease)...gives you
16,777,216 bytes. A file that is 4k x 4k x 24 bits/pixel (8 bits for each
color) gives you 50,331,648 bytes. Obviously, all that data isn't original
image data, it had to be "created" somehow...
