Document Summary
Pixel: a iny dot on the screen (form of measurement that makes up an image) Binary image (1 bit): black & white bit depth= 1. Grayscale (1 byte) or 8 bits: 256 gray levels of brightness (0 black 256 white) bit depth= 8. Color (3 bytes ) or 24 bits: 16. Rgb model (color model of red, green, and blue combinaions and levels) For red: (255,0,0,: blue: (0,0,255, green: (0, 255, 0, yellow (r+g): (255, 255, 0, cyan (g+b): (0,255,255, purple/magenta (r+b): (255,0,255, white (r+g+b): (255,255,255, black (0,0,0) Formula: width x height x bit depth= ile size. Binary 4 x 6 x 1= 24 bits. Grayscale image 4 x 6 x 8= 192 bits or 24 bytes. Color image 4 x 6 x 24= 576 bits or 72 bytes. You have more sample points to represent the same scene, the pixel dimensions of the captured image are increased. To encode an ininite number of colors within inite list.
