EFFICIENT TEST GENERATOR FOR VIDEO TEST PATTERNS

摘要

A video test pattern generator (100) and method include a control sequencer (106) configured to control one or more address counters (110, 112, 114, 116) to generate a video test pattern. A first memory (102) is configured to store pixel values for transitions between portions of the video test pattern and configured to store a repeated pixel value. A second memory (104) is configured to store pattern information to determine placement of the pixel values for the transitions and the repeated pixel values. A repeat counter (116) is configured to control a number of the repeated pixel values produced before a next transition.
