Thanks for reply. You are referring 4:2:2 or 4:4:4 as resolution and different shades of color (cb,cr) and luma(y) as color depth. Is it right?
I also read little more on 4:2:2 and this is what my understanding. If image is sampled for 4x4 pixels and sampled at resolution of 4:2:2, then there are 4x4 y channels and 4x2 channels for each cb, cr. Am I right?
Assuming that each channel (y,cb,cr)may need 8 for basic or more than 8 for deep color. I want to make sure that if 4x4 image is stored in
1. 4:2:2 at 10 bit deep color. The number of bits are
4x4x10 = y (first number tells number of rows, second number how many pixels are used in each row)
4x2x10 = cr
2. 4:4:4 at 8 bit. The number of bits are
4x4x8 = y
4x4x8 = cr
Does it makes sense?
