Patent number: 8842207Abstract: A recording mode control circuit controls a first recording mode in which still image data having a first image size corresponding to the number of pixels of an image sensing element is generated and recorded and a second recording mode in which moving image data having a second image size smaller than the first image size is generated and recorded. In generating the moving image data in the second recording mode, a camera signal processing circuit executes electrical zoom processing to obtain the second image size. At this time, a maximum magnification ratio setting circuit sets the maximum variable magnification ratio of electrical zoom processing in the camera signal processing circuit. With this processing, an image recording apparatus which allows a user to select a zoom mode with a small degradation in image quality in electrical zoom processing can be implemented.Type: GrantFiled: December 20, 2012Date of Patent: September 23, 2014Assignee: Canon Kabushiki KaishaInventor: Yoshiki Ishii
