The n bits per pixel produces 2 to the nth power shades of gray color.
00:11
So the shades of gray colors, 2 to the nth is equal to 128.
00:25
So 2 to the nth becomes equal to 2 to the 7th.
00:32
So by comparing the powers of 2 in our equation right here, we get the number of the bits required per pixel to be.
00:43
128 shades of gray color by solving for n and n is equal to seven for part b of the question we have the size of the color image and they tell us n is equal to 640 times 480 pixels so to find the number of bits required to store the color image n prime is equal to 2 is equal to 20 24n.
01:49
So 24n, we could substitute n into our equation.
01:56
So n prime gives us 7 .37 times 10 to the 6.

So on our pc, a personal computer, the size of the vhvga, jpeg image of our size, the first one, we have 496...
