1 June 1980 Real-Time Image Enhancement Using 3X3 Pixel Neighborhood Operator Functions
Author Affiliations +
A new type of silicon charge coupled device (CCD) imager which provides nine simultaneous video outputs representing a 3X3 pixel block that scans the imaging array has been used to emphasize edges and fine detail in various images. The device can also compensate for nonuniform scene illumination. Experimental results indicate that the device can be used to combine real-time analog image processing with subsequent digital processing to form a powerful image acquisition and processing system.
