ABSTRACT:
An image processing system uses a pseudo-random pixel interlace method and apparatus for capturing groups of pixels as image frames. This pseudo-random method eliminates the artifacts commonly present in standard regular line raster scan imaging systems. Moreover, the pixel interlacing method permits the construction of higher resolution frames from a series of orthogonal lower resolution frames. An enhancement circuit deduces information from previous pixel group frames and contributes additional detail to the pixels of the frame being processed. The format of the pixel interlaced groups permits the present invention to be used in a wide variety of normally incompatible target display rates. The present invention can also be used in a computing system as an auto-synchronizer for processing signals from different sources.
