Patent number: 11368624Abstract: An image capturing apparatus comprises an image sensor, and a controller that controls the image sensor to shoot images for display at a first cycle and controls to shoot a still image in response to the image shooting instruction. In a case where continuous shooting of still images is instructed during shooting the images for display at the first cycle, the controller changes a cycle at which the images for display are shot to a second cycle which corresponds to an integer multiple of speed of the continuous shooting while e continuous shooting is performed, and controls the image sensor to shoot the still images at the speed of the continuous shooting and shoot the images for display at the second cycle.Type: GrantFiled: September 3, 2020Date of Patent: June 21, 2022Assignee: CANON KABUSHIKI KAISHAInventors: Kazunori Takayama, Yasushi Ohwa, Minoru Sakaida, Yuji Omori

Patent number: 11356611Abstract: An image capture apparatus comprising an image sensor is disclosed. When an instruction to shoot a still image has been detected when executing a live view display, the image capture apparatus shoots the still image preferentially, while repeatedly displaying a same image during a period in which the live view display cannot be updated. The image capture apparatus reduces a luminance and/or changes a tone of the image that is repeatedly displayed.Type: GrantFiled: June 29, 2020Date of Patent: June 7, 2022Assignee: Canon Kabushiki KaishaInventors: Yasushi Ohwa, Kazunori Takayama, Minoru Sakaida, Yuji Omori, Takumi Ishikawa

Patent number: 11356603Abstract: An image capturing apparatus comprising an image sensor and a control circuit is disclosed. The control circuit changes, if a second drive period that is a drive period of the image sensor for still image shooting overlaps with a first drive period that is a drive period of the image sensor for moving image shooting, a start timing of the second drive period. When performing still image shooting while performing moving image shooting and moving image display: if the still image shooting is single image shooting or a first shot of continuous shooting, the control circuit does not change the start timing of the second drive period. If the still image shooting is a second shot onward of continuous shooting, the control circuit changes the start timing of the second drive period with giving priority to the moving image display.Type: GrantFiled: May 5, 2020Date of Patent: June 7, 2022Assignee: CANON KABUSHIKI KAISHAInventors: Yuji Omori, Yasushi Ohwa, Kazunori Takayama, Minoru Sakaida

Patent number: 9083882Abstract: An offset corresponding to an amount of geometric deformation is added to an amount of drive of an optical member due to an optical image shake correction so that the center of a reference area necessary for geometric deformation processing comes closer to the center of an imaging area. Because of this, a possibility is increased that a reference area necessary for geometric deformation processing is fully contained in an imaging area, and blurring of an image due to a motion of an image capture apparatus is effectively corrected by combining an optical image shake correction and a geometric deformation process.Type: GrantFiled: January 28, 2014Date of Patent: July 14, 2015Assignee: CANON KABUSHIKI KAISHAInventor: Kazunori Takayama
