Abstract :
An electronic zoom system for video camera use has been developed. Zoom ratios were designed to be smoothly changed vertically and horizontally by controlling imager scanning and line memory scanning, respectively. Two CMOS digital LSIs, a scanning pulse generator, and a signal zoom processor were developed for this electronic zoom system
