The zoom speed of a zoom function is detected by a zoom lever detection circuit. A sensed image is displayed on a monitor, and a desired partial region in that sensed image is designated using a region designation lever. A compression circuit compresses the designated region and a non-designated region using different characteristics. A region detector controls the designated region on the basis of the detected zoom speed. In another arrangement, enlargement/reduction zoom operation by a zoom function is executed by a zoom lever. A sensed image is displayed on a monitor, and a desired partial region in that sensed image is designated using a region designation lever. A compression circuit compresses the designated region and a non-designated region using different characteristics. A region detector controls the designated region on the basis of the zoom operation.
