Optical System For An Electronic Still Video Camera

H. Yokota; Masatake Kato; A. Shiraishi

As a core of the Canon still video system, we have developed an electronic still video (SV) Tamera, RC-701, which records image information on a standard 2 inch video floppy disk. The RC-701 is composed of a 2/3 inch CCD, a viewfinder, signal processing circuitry, a disk drive unit and system control circuitry which controls the functions of all units. This report represents the analyses for designing the optimum viewfinder optical system of the RC-701, by solving various restricting factors caused from the structure of the SV camera, and introduces optical components used in the RC-701.
