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: 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: 11050928Abstract: There is provided an image capturing control apparatus. A first control unit performs control to repeatedly obtain an evaluation image using an image sensor. The evaluation image is used to obtain an evaluation value for controlling at least one of image capturing and development. An obtaining unit obtains the evaluation value on the basis of the evaluation image. A second control unit performs control to temporarily stop the obtainment of the evaluation image and use the image sensor to obtain, during a stopped period, a still image for recording. A generating unit generates an estimated evaluation image corresponding to the stopped period on the basis of two or more evaluation images obtained outside the stopped period. For the stopped period, the obtaining unit obtains the evaluation value on the basis of the estimated evaluation image.Type: GrantFiled: August 25, 2020Date of Patent: June 29, 2021Assignee: CANON KABUSHIKI KAISHAInventors: Minoru Sakaida, Yasushi Ohwa
