Avoiding parallax errors between a zoom lens and an optical viewfinder of an electronic camera

摘要

An electronic camera (1) having an image sensor (4) to receive the rays of an object (10) and convert them into the electrical image signals comprises an optical finder (3) capable of varying its enlarging magnification or photographing area; reading means (5) to read the signals of a part of the area of the image the rays of which are received by the image sensor; and reading area modifying means to modify the size of the area thereby to read the signals from the image sensor in accordance with the enlarging magnification of the finder or the displayed photographing area. Further, such an electronic camera comprises metering means (7) to measure the distance between an object and the taking lens (62), and the foregoing reading area modifying means modifies the size and position of the area thereby to read the signals from the image sensor in accordance with the finder magnification or the displayed photographing area and the measured value by the metering means. This prevents from the parallax phenomenon between the zoom lens and the optical finder.
