GRAPHICSImage Representation

Images on a monitor

Image Representation

Image Representation• Each pixel can be represented it by its 3

actual RGB values• The value scale has 256 different values

• Each value is a number between 0 and 255 and one needs 8 bits to represent such a number therefore 8+8+8=24 bits to fully represent an RGB color on a single pixel

• Size of a color image: w * h * 24 bits = (w * h*24)/8 B

A 640 x 480 color image takes 921,600 B = 900 KB!

Resolution

• Resolution usually refers to the number of pixels on a surface whether a display or image

• Resolution terminology varies according to the intended output device. • PPI (pixels per inch) refers to screen resolution (monitors)• DPI (dots per inch) refers to print resolution

• Images are displayed on your computer screen at display (or screen) resolution (72 or 96 ppi).

• The typical desktop printer needs 150-300 dpi.

Resolution

Resolution: Scaling up

More resolution, but not more details..

GRAPHICSRaster VS Vector

Raster Graphics

• Graphics made up of tiny squares

• Squares are called “pixels”

• Pixel is short for picture element

• Not scalable

Vector Graphics

• The computer stores the information as lines and curves

• Created using math formulas

• Example:

The computer does not remember what the circle looks like. It remembers the center point and area of the circle and then redraws the image.

Raster VS Vector

Raster

Raster VS Vector
