Abstract
An electronic camera includes an image sensor. The image sensor has an imaging surface capturing an object scene through a zoom lens, and outputs an image representing the object scene. The image outputted from the image sensor is reduced in size by a zoom circuit arranged in a pre-processing circuit. A post-processing circuit extracts a reduced image belonging to an extraction area of a predetermined size, out of the reduced image created by the pre-processing circuit. Depending on a change of a magnification of the zoom lens, a CPU changes a size of the reduced image created by the pre-processing circuit in the same direction as a change direction of the magnification of the zoom lens. An angle of view of the reduced image extracted by the post-processing circuit decreases by a rate exceeding a decrease rate resulting from an increase in optical zoom magnification.
