Patent number: 10586392Abstract: Information representing a position and orientation of a captured image or information for deriving the position and orientation is acquired from the captured image as extraction information, and a reduced-information-amount image is generated by reducing an amount of information in the captured image in accordance with a distance from a position that a user is gazing at in the captured image. The reduced-information-amount image and the extraction information are outputted to an external device, and a composite image that has been generated based on the reduced-information-amount image and an image of a virtual space generated by the external device based on the extraction information is received.Type: GrantFiled: November 21, 2017Date of Patent: March 10, 2020Assignee: CANON KABUSHIKI KAISHAInventors: Kazutaka Inoguchi, Atsushi Hamaguchi

Patent number: 9136309Abstract: An organic electroluminescent (EL) display includes a plurality of organic EL devices for red, green, and blue subpixels, each including a first electrode on a light output side, a second electrode opposite the first electrode, and an organic compound layer including a light-emitting layer therebetween. The organic EL devices have a resonator structure between a first reflective surface closer to the first electrode than the organic compound layer and a second reflective surface closer to the second electrode than the organic compound layer. A predetermined white color is displayed by mixing the three colors such that an optical distance of the organic EL devices of each color between an emission position in the light-emitting layer and the second reflective surface is set within ±10% from an optical distance corresponding to an nth-order minimum of a curve of required current density against at least the optical distance.Type: GrantFiled: October 31, 2013Date of Patent: September 15, 2015Assignee: Canon Kabushiki KaishaInventors: Atsushi Hamaguchi, Nobutaka Mizuno

Patent number: 7259745Abstract: A method for driving a display apparatus having display memory property is provided. In the method, the display apparatus includes an electrode group composed of at least a first electrode and a second electrode. The method includes the steps of: applying a voltage for performing writing of an display image between the first electrode and the second electrode; and attenuating an absolute value of a potential difference between the first electrode and the second electrode in a term within a holding period of the display image. Thereby, the deterioration of a holding characteristic owing to the influence of a residual DC can be prevented.Type: GrantFiled: March 3, 2004Date of Patent: August 21, 2007Assignee: Canon Kabushiki KaishaInventor: Atsushi Hamaguchi
