Abstract
Towards an intelligent image sensor with visual image processing function, preliminary bioelectronic image sensing system based on photoelectric function of protein bacteriorhodopsin was fabricated. The image sensing system consists of two functional parts: image detection including bacteriorhodopsin and supplementary feature extraction. Image detection, in which bacteriorhodopsin molecules are used as motion extraction elements, extracts image data relating only to moving object in movie images, whether background image was a pattern or not. The detected image data was a mix of different types of features, i.e., edge, moving direction, and region of moving object. The supplementary feature extraction part separates and categorize feature information from the detected images accordingly. Considering a total efficiency for feature extraction of moving object, we conclud that utilization of photo-response protein for intelligent image sensing system will enable us a realization of high-efficient intelligent image sensor.
