ABSTRACT:
A camera for sensing image information and accurately and quickly reducing such information to a plurality of black and white analog voltages corresponding to pixels of a line image scan. A sensor of the CCD type generates a plurality of electron packets which are read out as two analog voltages. After d.c. restoration and normalization, the analog voltages are promptly converted to gray scale digital values to preserve maximum image information for subsequent processing. Thereafter, the digital signals are reordered to correspond to the physical ordering of the photocells of the sensor and applied to a hybrid digital filter for rapid hybrid (analog/digital filter) image enhancement.
