IMAGE PICKUP APPARATUS AND CONTROL METHOD FOR SAME

摘要

Provided is a compound-eye image pickup apparatus in which a plurality of imaging units, each of which configured to photoelectrically convert an optical image focused by a single focal lens with different focal length so as to output a signal, are arranged in the form of a matrix. An image processing unit performs an electronic zoom process for changing a cut-out area of an image and a filtering process for an image signal. A system controller obtains information relating a change in zoom magnification from a zoom changing unit and data relating to a zoom control method from a zoom control method storage unit so as to instruct a zoom controller to perform zoom control. Upon change of an angle of view by controlling the electronic zoom process and the switching of the single focal lens, the zoom controller controls the filtering process performed by the image processing unit so as to equalize the resolution before and after the switching of the single focal lens.

1. An image pickup apparatus in which a plurality of imaging units each having a lens with 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 the 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 a change of the imaging unit and the electronic zoom process, wherein the control unit changes the imaging unit upon change of a zoom magnification and performs control for suppressing a change in resolution of an image by the filtering process performed by the image processing unit before and after the change of the imaging unit upon change of an electronic zoom magnification by the image processing unit.
