Converting bits to bytes

Slide 17 - Tekstslide

Resolution = 800 x 500

Colour depth = 24 bits

800 X 500 = 400,000 pixels

500,000 pixels x 24 bits per pixel = 12,000,000 bits (12 megabits)

500,000 x 3 bytes per pixel = 1,500,000 (1.5 megabytes)

Slide 18 - Tekstslide

Resolution = 500 x 400

Colour depth = 24 bits

Slide 19 - Tekstslide

Slide 20 - Tekstslide

resolution = 640 x 500 = 320,000 pixels

size = 320,000 pixels x 3 bytes per pixel

size = 960,000 bytes

960,000 bytes is 0.96 megabytes
