Abstract—A computer, the Visual Image Processor, is described which is designed to process visual images. Images are read by a vidicon camera and stored in any of three identical cathode-ray electrostatic storage tubes. Two storage systems are read simultaneously, with the reading beams spatially displaced from each other, and a signal which is a function of the reading signals is written into the third storage system. The spatial displacement of the reading beams and the function are variable and under control of the computer operator.
