Patent number: 9973698Abstract: A method of determining stability of a camera comprises capturing an image with the camera and then (A) determining a magnitude of motion for each region of a current sub-division of the image. A step (B) then determines a number of the magnitudes of motion not larger than a magnitude threshold associated with the current sub-division, and where the determined number is greater than or equal to a region threshold associated with the number of regions in the current sub-division, (i) determining the camera to be stable, or otherwise (ii) dividing the current sub-division of the image into a further sub-division and repeating steps (A) and (B) upon the further sub-division.Type: GrantFiled: November 24, 2014Date of Patent: May 15, 2018Assignee: Canon Kabushiki KashiaInventors: Quang Tuan Pham, Amit Kumar Gupta

Patent number: 6110347Abstract: A method for forming an indium oxide film on an electrically conductive substrate by immersing the substrate and a counter electrode in an aqueous solution containing at least nitrate and indium ions and flowing an electric current between the substrate and the couter electrode, thereby causing indium oxide film formation on the substrate, is provided. A substrate for a semiconductor element and a photovoltaic element produced using the film forming method are also provided. An aqueous solution for the formation of an indium oxide film by an electroless deposition process, containing at least nitrate and indium ions and tartrate, is also disclosed. A film-forming method for the formation of an indium oxide film on a substrate by an electroless deposition process, using the aqueous solution, and a substrate for a semiconductor element and a photovoltaic element produced using the film-forming method are further provided.Type: GrantFiled: October 15, 1998Date of Patent: August 29, 2000Assignee: Canon Kabushiki KashiaInventors: Kozo Arao, Katsumi Nakagawa, Yukiko Iwasaki

Patent number: 6006055Abstract: An image forming apparatus includes a movable image bearing member, a charging member, a developer, and an auxiliary member. The charging member contacts the image bearing member to electrically charge the image bearing member. The developer develops, with toner, an electrostatic image formed on the image bearing member using a charging operation of the charging member. The developer is capable or removing residual toner from the image bearing member simultaneously with its developing operation for the electrostatic image. The auxiliary member is disposed upstream of the charging position and downstream of a transfer position where the toner image is transferred from the image bearing member onto a transfer material with respect to a movement direction of the image bearing member.Type: GrantFiled: August 31, 1998Date of Patent: December 21, 1999Assignee: Canon Kabushiki KashiaInventor: Tadashi Furuya

Patent number: 5758038Abstract: An image forming apparatus has a plurality of image forming units for forming, on an image receiving member such as a transfer sheet, toner images of a plurality of different colors such as magenta, cyan, yellow and black. Each of the image forming units includes a photosensitive drum serving as an image carrier, a developing device for developing an electrostatic latent image carried by the image carrier to form a color toner image, and a transfer device for transferring the toner image to the image receiving member. The developing device in the image forming unit for forming on the image receiving member the toner image of an (i+1)-th color is of the type capable of simultaneously performing both development and removal of residual toner. The transfer currents T.sub.i and T.sub.i+1 employed by the transfer units which perform transfer of the toner images of an i-th color and the (i+1)-th color satisfy the following condition (1).Type: GrantFiled: July 9, 1996Date of Patent: May 26, 1998Assignee: Canon Kabushiki KashiaInventors: Masahiro Itoh, Kenichiro Waki, Hiroyuki Suzuki, Ryo Inoue
