ABSTRACT:
A camera image data processor provides scan conversion at extremely high speed while allowing static and dynamic correction of image data particularly for a high data output rate CCD image transducer in a confocal imaging system for automated optical inspection in manufacturing processes. Scan conversion and data collation is accomplished at bit rates in excess of 1 Gigabyte by accessing a double buffer memory with different sequences of addresses covering a field of an image corresponding to a field in the memory during read and write operations. Highly parallel output is provided for confocal height data in a raster line by providing a delay equal to an integral multiple of the access time for a field for each confocally imaged height within a sample.
