A pixel data conversion method for display with delta panel arrangement converts an input video signal into a temporary video signal which is a first RGB signal with 960 horizontal resolution in strip panel arrangement and converts the temporary video signal into an output video signal which is a RGB signal with 320 horizontal resolution in delta panel arrangement. Each line of the output video signal has 960 pixels, wherein a sequence of red pixel, green pixel, and blue pixel is repeatedly arranged for an odd-numbered horizontal line, and a sequence of green pixel, blue pixel, and red pixel is repeatedly arranged for an even-numbered horizontal line. The position of each pixel in an even-numbered horizontal line has a half-pixel dislocation to the position of each pixel in an odd-numbered horizontal line.

Pixel data conversion apparatus and method for display with delta panel arrangement

A method of fixed bit-rate image compression/decompression based on 2&#xd7;2 image unit encodes an image that is divided into a plurality of 2&#xd7;2 coding units. The method determines whether a 2&#xd7;2 coding unit has one of first to seven man-made patterns. When the 2&#xd7;2 coding unit has one of the first to seven man-made patterns, a differential error encoding and a quantization and look-up are performed on the 2&#xd7;2 coding unit for generating a first coded data. Otherwise, the 2&#xd7;2 coding unit is a natural pattern, and the method sequentially performs a color domain transform, a discrete cosine transform, and a quantization and look-up on the 2&#xd7;2 coding unit for generating a second coded data.
