Abstract
Abstract A video compressor for use in an image processing system is provided. The compressor includes structure for detecting a data image pattern and for generating a code representing the detected data image pattern. A counter counts the number of times a data image pattern is detected and generates a repeat count. The code is stored in a fixed sized bit field. The repeat count is stored in a variable sized bit field. Structure is provided for merging the fixed sized bit field and the variable sized bit field into a continuous bit field.
