Pixel Values

Consider the 5x5 matrix with 4 bit numbers (shown in the attached file).

Consider a color code of 4 colors: Black, Red, Yellow, and White.

Assume that the 4 colors are used to represent the entire range of pixel values. Color the squares with the appropriate colors.

Solution Preview

Range of (pixel) values with 4 bit numbers would be 0-15. However your color code consists of just 4 colors that are used to represent the entire range of pixel values. One way to achieve this would be to map a set of contiguous pixel values to single color value as shown below.

Pixel Value -> Color Code Value
0,1,2,3 -> 0
4,5,6,7 -> 1
8,9,10,11 -> 2
12,13,14,15 -> 3

Alternatively above mapping can be expressed as:

Pixel Value -> Color Code Value
0000 ...
