Color Code

The document explains image representation, focusing on how the number of bits per pixel determines the color depth and the total number of colors available. It defines color depth and image resolution, noting that modern computers typically use a 24-bit color depth, allowing for over 16 million colors. Additionally, it states that higher resolution images contain more detail compared to lower resolution images.

1. IF EACH PIXEL IS REPRESENTED BY THREE BITS, THEN EACH PIXEL CAN BE
ONE OF EIGHT COLOURS (000,001,010,011,100,101,110,111)

DEFINITION:
COLOUR DEPTH: THE NUMBER OF BITS USED TO REPRESENT EACH COLOUR
IS CALLED THE COLOUR DEPTH.

l IMAGE REPRESENTATION j

ONE BIT - 2 COLOUR (0,1)


TWO BIT - 4 COLOUR (00,01,10,11)
THREE BIT - 8 COLOUR (000,001,010,011,100,101,110,111)

EIGHT BIT - ?

TOTAL NUMBER OF COLOURS: 2 "(NUMBER OF BITS)

MOST MODERN COMPUTERS HAVE A 24 BIT COLOUR DEPTHS,


WHICH MEANS OVER 16MILLION DIFFERENT COLOURS CAN BE USED.
