A “picture element” that contains the light intensity at some location (i,j) in the image
i, j
I(i,j) = some numeric value
width * height
= 1280 * (1280 /2)
= 0.8192mp image

image can be represented as a matrix
intensity value range from 0 = black to 255 = white
two dimension array
8 bits allow to represent 2^8 = 256 different values
Digital image is a Function
