Publication number: 20100171862Abstract: In the beginning, display screens were monochrome, and a video artist was limited to specifying the brightness of a pixel. With the advent of color display screens, the artist could specify the color and brightness of a pixel. With this invention, the artist can now additionally specify the direction from which that color and brightness can be seen. I anticipate a single pixel being capable of displaying different colors in different directions at the same time. This invention also describes a camera capable of capturing this directional information.Type: ApplicationFiled: January 5, 2010Publication date: July 8, 2010Inventor: Earl Alexander Culham

Publication number: 20030103157Abstract: The invention makes a suitable selection from zoom modes and lens elements so thin that the thickness of each lens group can reduced, thereby slimming down a zoom lens with great thoroughness and, hence, an electronic image pickup system. The electronic image pickup system a zoom lens and an electronic image pickup device located on the image plane side of the zoom lens. The zoom lens comprises, in order from the object side, a first lens group G1 comprising two lens components and having generally negative power and a second lens group G2 comprising two lens components and having generally positive power. The focal length of the zoom lens can be varied by varying the air separation between the first lens group G1 and the second lens group G2. The zoom lens should satisfy at least one of conditions (a) to (n).Type: ApplicationFiled: April 3, 2002Publication date: June 5, 2003Applicant: OLYMPUS OPTICAL CO., LTD.Inventors: Masahito Watanabe, Toru Miyajima, Shinichi Mihara, Yuji Miyauchi, Toshihide Nozawa, Hisashi Goto

Patent number: 6536960Abstract: In a digital camera having a half mirror retractable out of the optical path and an optical viewfinder receiving light reflected from the half mirror, the sensitivity of an image-sensing device is set as specified by the user. When a relatively high sensitivity is specified, an image to be recorded is shot with the half mirror operated as a quick-return mirror, and, when a relatively low sensitivity is specified, an image to be recorded is shot with the half mirror kept in the optical path. A sensitivity that cannot be coped with simply by changing the position of the half mirror is set by adjusting, in conjunction therewith, the output gain of the image-sensing device.Type: GrantFiled: December 7, 2000Date of Patent: March 25, 2003Assignee: Minolta Co., Ltd.Inventors: Hiroaki Kubo, Yasuhiro Morimoto

Patent number: 6535248Abstract: A camera of the present invention is selectively operable in a normal mode or a macro mode and includes a macro mode alarm device. When the operator of the camera selects the macro mode on a normal/macro mode switch while seeing a subject through an optical finder, a controller feeds an alarm control signal and an LCD (Liquid Crystal Display) control signal to the macro mode alarm device and an electronic finder, respectively. In response, the macro mode alarm device causes a light emitting element disposed in an optical finder to glow or blink, urging the operator to use the electronic finder in place of the optical finder. In addition, the controller turns on power supply to the LCD of the electronic finder so as to allow the operator to use the electronic finder immediately.Type: GrantFiled: June 2, 1998Date of Patent: March 18, 2003Assignee: Fuji Photo Film Co., Ltd.Inventor: Koki Hatakeyama

Publication number: 20020158973Abstract: A system controller controls a solid-state image sensor, and performs read-out at a predetermined subsampling ratio. In the event that the size of the image-taking area and the subsampling ratio do not agree, the system controller executes image size conversion processing with a digital processing unit, and converts the image size to an image size corresponding to a request from a peripheral device unit. Also, the system controller performs changing of the image-taking area following ending of the reading out from the solid-state image sensor, thereby obtaining normal frame signals. Accordingly, even in the event that zooming is performed by changing the subsampling ratio, zooming operations can be performed with an arbitrary zooming ratio, and reading out of the image-taking information is made to be suitable.Type: ApplicationFiled: April 26, 2002Publication date: October 31, 2002Inventor: Yuichi Gomi
