This paper describes a versatile multi-window vision system, which is developed for providing robots with flexible and multiple visual attention capability. Chapter 1 is introduction. A window is a local region to be processed for one attention. The multi window vision system provides a large number of windows. The location, shape, size, and resolution of each window can be controlled by a special LSI, independently and simultaneously. In Chapter 2, we describes the concept and architecture of the multi window vision system. The multi window vision system is designed to build a pandemonium model by means of multi microprocessors. In order to avoid the image access bottleneck in parallel processing, we introduced a transmiter-receiver into the multi window vision system. Chapter 3 describes the transmitter unit which broadcasts input images to the window receivers. In Chapter 4, the details of the logic circuits inside the window control LSI is described. The LSI chip controls window parameters which are location, size, shape, spatial sampling rate, window memory access, and the display of the window image. In Chapter 5, the image processing unit that implements the LSI chips is described. Chapter 6 shows the experimental results using the image processing unit. Chapter 7 is Concluding Remarks.
