Claim:
1. An image pickup apparatus in which a plurality of imaging units, each having a lens with a different focal length and an imaging element, are arranged in a form of a matrix, the image pickup apparatus comprising: an image processing unit configured to perform an electronic zoom process for changing an electronic zoom magnification by changing a cut-out area of an image relating to an image signal output from a selected imaging element and to perform a filtering process for a pixel value of the image in the cut-out area; and a control unit configured to perform zoom control by changing the selected imaging unit and performing the electronic zoom process, wherein the control unit changes the selected imaging unit upon a change of a zoom magnification and performs control for suppressing a change in a resolution of the image by the filtering process performed by the image processing unit before and after the change of the selected imaging unit upon the changing of the electronic zoom magnification by the image processing unit, and wherein the control unit calculates a filtering coefficient, for use in the filtering process, using a ratio of a number of cut-out lines of the image to a number of lines that correspond to the changed resolution.
