ABSTRACT:
An artificial retina cell effectively used to recognize a plurality of objects from an image containing them with ease and at high speed. Also disclosed are an artificial retina and an artificial visual apparatus employing the same. The artificial visual apparatus includes an artificial eyeball (3) having a focusing means (2) and an artificial retina (1) including a first artificial retina cell disposed in a central visual field (1a) to detect a bright-dark boundary by optical filtering and a second artificial retina cell disposed in a peripheral visual field (1b) to detect an object position by optical filtering, and a neural network (4) for executing pattern recognition of an object on the basis of information detected by the first artificial retina cell. The apparatus further includes a means for determining an object to be recognized subsequently from information detected by the second artificial retina cell of the artificial retina (1), and a means (5) for moving the artificial eyeball (3) toward the object to be recognized. Thus, a specific object in an image containing a plurality of objects of recognition is selectively recognized with ease and at high speed.
