By means of integration of an imager and parallel processing elements on a chip, we have studied on realization methods of instantaneous processing/response system of image data that is comparable to a biological vision system. The following results have been achieved.[Visual feedback control system] For the instantaneous visual processing and control, we have designed a chip integrating photo detectors and digital general purpose processing elements. 16 x 16 pixels with processing elements has been integrated on a 5mm x 5mm chip, that operates 100MHz/600mW. A controller for the vision chip and its programming system has also implemented for successful demonstration of the visual feedback system based on the developed vision chip.[High quality imager with data compression] For simultaneous realization of high quality imager and suppression of data bandwidth, we have successfully integrated image-processing functions into an imager.

A 128 x 128 imager has been realized to demonstrate the performance. We have also realized a 64x 64 variable special resolution imager, which adaptively changes its resolution depending on target objects. It has a similarity to that of the biological retina.[Tracking system of moving objects] For instantaneous detection of motion vectors of moving objects, we have developed a hierarchical block access imager utilizing the binary image/binary outline of objects. This sensor can access a volume of pixels at a time, so as to detect moving directions of objects comparing the successive image frames on a chip.[Adaptive vision] For simulating the adaptability of biological vision system, we have designed a 1-D artificial silicon retina that has capabilities of spatial derivative calculation and smoothing.
