Abstract
A cost-efficient digital parallel processor to improve throughput and offer a variety of output formats in film conversion is described. Image pixels on film are translated into electrical signals by photosensitive detectors. The electrical signals are digitized by analog-to-digital converters and thereafter provided to a digital parallel processor for film conversion functions. The digital parallel processor includes two or more groups of circuit elements to facilitate parallel processing. Each group of circuit elements can process a different set of image pixels simultaneously. In addition, image pixels belonging to the same set can be processed in parallel. This two-dimensional parallel processing structure facilitates faster than real-time film conversion sessions. A supervisor control circuit monitors and controls the sequence of film conversion functions. The output of the digital parallel processor is provided to a formatter which manipulates the data to conform to one or more standard formats. The data in different standard formats can be provided in parallel, thereby eliminated the need for additional film conversion sessions. The data in standard formats can be stored in …
