Abstract
Several techniques for implementing optical parallel logic are proposed using parallelism of image.1-3 However, image has inherent features which are not only parallelism for processing but also visual interface for human. Therefore, we have proposed the visual area coding technique (V-ACT) for optical computing which enables us to visualize the result by introduction of digital halftoning.4 This paper shows the capacity of the visual area coding technique (V-ACT) in the field of gray image processing.
