Patent number: 9812070Abstract: A display apparatus has: a display unit; a light emitting unit for outputting irradiation light; a light detecting unit; an external light intensity specifying unit; and a correcting unit. When the external light intensity is equal to or smaller than an external light determination threshold value and the intensity of light detected by the light detecting unit under irradiating the irradiation light is equal to or smaller than a detected light determination threshold value larger than the external light determination threshold value, an irradiation light intensity is corrected by using a first correcting method. When the external light intensity is larger than the external light determination threshold value or the intensity of light detected by the light detecting unit under irradiating the irradiation light is larger than the detected light determination threshold value, the irradiation light intensity is not corrected or corrected by using a second correcting method.Type: GrantFiled: July 29, 2016Date of Patent: November 7, 2017Assignee: Canon Kabushiki KaishaInventor: Daisuke Takayanagi

Patent number: 8687119Abstract: When a video output apparatus (100) is connected, a video display apparatus (200) obtains information of content data stored in the video output apparatus (100). Then, based on the obtained information, the video display apparatus (200) determines whether the content data is decodable with respect to itself. If it is not decodable, it requests the video output apparatus (100) to decode the content data before transferring the content data using a data transfer method specified. By doing this, an appropriate transfer protocol is selected automatically when transferring content data between the video display apparatus (200) and the video output apparatus (100).Type: GrantFiled: May 10, 2012Date of Patent: April 1, 2014Assignee: Canon Kabushiki KaishaInventors: Teruki Kikkawa, Yoshikazu Shibamiya, Yasushi Shikata, Hirofumi Urabe, Daisuke Takayanagi, Chika Masuda

Patent number: 8630499Abstract: When an image processing apparatus capable of connecting to a digital camera is to perform image-correction processing on irreversible-compression encoded image data acquired from the digital camera, it is determined whether the image-correction processing can be executed by the connected digital camera. When the processing can be executed, it is confirmed whether or not RAW data that corresponds to the irreversible-compression encoded image data is present in the digital camera. If the corresponding RAW data is present in the digital camera, the digital camera is requested to execute the image-correction processing based on the RAW data. This makes it possible to suppress degradation in the image quality more than when directly correcting an irreversible-compression encoded image.Type: GrantFiled: November 19, 2008Date of Patent: January 14, 2014Assignee: Canon Kabushiki KaishaInventors: Yasushi Shikata, Teruki Kikkawa, Yoshikazu Shibamiya, Hirofumi Urabe, Daisuke Takayanagi, Chika Masuda
