Computer Science for IGCSE & O level - Data Representation (Section 11 - No. 42)
If an image is 1920 pixels wide and 1080 pixels high and has a color depth of 8 bits (256 colors), what is its uncompressed size in bytes?
1920 * 1080 bytes
1920 * 1080 * 8 bytes
1920 * 1080 / 8 bytes
(1920 * 1080 * 8) / 1024 bytes
Forklaring
With 8 bits per pixel, you need 1 byte per pixel (8 bits/8 bits per byte = 1 byte/pixel).
