This paper discusses the semiconductor integrated circuit device called a vision chip, an image sensor in which each pixel has a processing element. Although similar devices have already been proposed, the major features of our device are dynamically reconfigurable PE architecture that is efficient for both local and global operation, and dynamic control mechanism of sensor characteristics. These features are advantageous to robot applications that require high-speed visual feedback and task operation in changing environment. We show the basic working principle based on the patent (#2003-218338) and explain the expected market with business model.
