Bits for pictures
Did you know that …
1 bit can also be used to code pictures?
2 the information displayed on the computer screen corresponds dot by dot, with bits held in the main memory?3 on colour systems, if you have 8 bits per primary colour, the palette of your computer can obtain 16,7 million colours?
Each tiny dot on the screen of computer is called a picture element orpixel images and text are formed by combining a large number of pixels.
In a bit-mapped display, the dots displayed on the screen correspond, pixel by pixel, with bits in the main memory of thecomputer. The bits are held in an area of the memory called the ‘refresh buffer’ and are stored in groups that represent the horizontal and vertical position of the pixels on the screen and whether thepixels are on or off.
On monochrome systems, one bit in this ‘map’ represents on pixel on the screen and can be either ‘on’ or ‘off’ (black or white).
On colour systems, each pixel is a certaincombination of the three primary colours: red, green and blue. That total number of colours which can be shown on the screen is called the colour palette. The size of this palette depends on the graphicsadaptor with 1 bit per primary colour can generate up to 8, or 23, colours, as you can see from the table on page 19. A graphics adaptor with 8 bits per primary colour can generate 16.7 million or(23)8 colours.
