An image pickup apparatus is disclosed to prevent recording of a degraded image by restricting setting of an electronic zoom function when a recording mode is set to a low-compression ratio mode or non-compression mode. The image pickup apparatus comprises a processing device for electronically enlarging an image picked up by an image pickup unit, a setting device for setting compressing operation for the image picked up by the image pickup unit, and a control device to restrict operation of the processing device in accordance with the compressing operation for the image which is set by the setting device. When a compression ratio equal to or less than a predetermined value is set by the recording mode setting unit or the non-compression mode is set, a system control circuit inhibits the electronic zoom function that tends to cause a deterioration in image quality from being turned on.
