ABSTRACT:
A scene which is divided into a plurality of pixels is raster scanned. During each scan an analog signal derived from a binary number and representing a given light intensity is compared against other analog signals representing the light intensity of each of the pixels. At any time when the light intensity of a pixel is greater than the given light intensity, the binary number associated with that given light intensity is stored in a register of a multiregister memory whose registers are assigned to the respective pixels. After each scan the given light intensity is increased.
