We, human beings, can find signals at intersections and lavatory marks easily because we can recognize an object by gazing at it for about one second after selecting only some suitable objects in some hundred miliseconds in a wide and multi-band animation image detected by more than 100 million cones and rods in a retina, whose view angle is more than 150 degrees. A visual device is a model of such a visual mechanism of our brains, characterized by a MIMD-type array architecture and some local and parallel image processing algorithms. In order to develop a seeing-eye robot with an artificial eye carrying the visual device, now, our project is making an LSI of the visual device and its development environment. In this report, we estimate amount of transmit data after explaining about position/size detection algorithm that plays an important role in the visual device.
