Patent number: 11842469Abstract: An apparatus includes at least one memory configured to store instructions, at least one processor in communication with the at least one memory and configured to execute the instructions to receive a photographing instruction, and an optical system configured to perform a first photographing method before reception of the photographing instruction, and a second photographing method after reception of the photographing instruction. The at least one processor further executes instructions to combine a plurality of first images at different in-focus positions captured by using the first photographing method with a plurality of second images at different in-focus positions captured by using the second photographing method. The optical system performs readout an image sensor, while keeping the drive of a focus lens, in the first photographing method, and stops the focus lens at different positions in the second photographing method.Type: GrantFiled: March 18, 2021Date of Patent: December 12, 2023Assignee: CANON KABUSHIKI KAISHAInventors: Saori Hoda, Masanao Yokoyama, Masahiro Yamashita, Hiroshi Yamazaki

Patent number: 9106834Abstract: An image display controller capable of providing excellent visibility of a face display frame and a human display frame associated with an object. The image display controller detects an object in an image, and identifies a face area of the object distinguishably from a human body area exclusive of the face area. Further, the image display controller generates a face display frame for enclosing the face area and a human body display frame for enclosing the human body area. Then, the image display controller displays the face display frame and the human body display frame on a screen together with the image.Type: GrantFiled: February 7, 2012Date of Patent: August 11, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Saori Hoda, Yoshinobu Sato, Yasushi Ohwa, Yusuke Takeuchi, Hiroshi Yamazaki

Publication number: 20120306740Abstract: An information input device that enables a user to input information easily by a single hand. The information input device inputs information using a virtual item displayed on a display unit. An image pickup unit shoots an indicator that operates the virtual item continuously to obtain indicator image data. A display control unit displays an indicator image corresponding to the indicator image data on the display unit. A setting unit sets, when detecting an action of the indicator to an element included in the virtual item displayed on the display unit, information corresponding to the element concerned as input information.Type: ApplicationFiled: May 22, 2012Publication date: December 6, 2012Applicant: CANON KABUSHIKI KAISHAInventor: Saori Hoda
