Patent number: 10264180Abstract: An apparatus which corrects magnification chromatic aberration of image data, and includes an image processing circuit. The image processing circuit corrects magnification chromatic aberration with respect to picked-up image data which has been picked up by an image sensor through an image pickup optical system that includes a correcting lens that corrects an image blur by shifting a position of the correcting lens. In accordance with an operation amount of the correcting lens, the image processing circuit selects and executes either of a first correction process in which a correction amount stored in a memory in advance is read to correct magnification chromatic aberration, or a second correction process in which a correction amount is calculated using the picked-up image data to correct magnification chromatic aberration.Type: GrantFiled: December 16, 2016Date of Patent: April 16, 2019Assignee: CANON KABUSHIKI KAISHAInventor: Hidetoshi Nishigori

Patent number: 9607361Abstract: An image processing apparatus performs distortion aberration correction appropriate for each of the cases where the image processing apparatus clips image data by performing electronic image stabilization and does not clip the image data by performing the electronic image stabilization. The image processing apparatus includes a correction unit configured to perform the distortion aberration correction on image data in which distortion aberration has, and a stabilization unit configured to perform clipping from the image data based on a movement of an imaging unit when the image data has been generated. The correction unit reduces an amount of the distortion aberration correction in a case where the stabilization unit does not clip the image data, as compared to a case where the stabilization unit clips the image data.Type: GrantFiled: September 15, 2016Date of Patent: March 28, 2017Assignee: CANON KABUSHIKI KAISHAInventor: Hidetoshi Nishigori

Patent number: 8908088Abstract: An image pick-up apparatus that is capable of correcting shading due to a closing travel operation of a shutter by a simple process. An image pick-up device picks up the image formed. A shutter unit opens and closes a substantially rectangular aperture corresponding to image pick-up area of the image pick-up device by means of a plurality of rotating shutter blades. The shutter blades travel in mutually opposite directions perpendicular to a long side of the aperture while keeping edges of the shutter blades facing the aperture are parallel to the long side so that edge portions that cover a center area of the aperture start shading the aperture before edge portions that cover four corner areas of the aperture start shading the aperture.Type: GrantFiled: February 11, 2013Date of Patent: December 9, 2014Assignee: Canon Kabushiki KaishaInventors: Toru Ishimasa, Hidetoshi Nishigori
