Patent number: 8786730Abstract: Calculating a gain setting for a primary image sensor includes receiving a test-matrix of pixels from a test image sensor, and receiving a first-frame matrix of pixels from a primary image sensor. A gain setting is calculated for the primary image sensor using the first-frame matrix of pixels except those pixels imaging one or more exclusion regions identified from the test matrix of pixels.Type: GrantFiled: August 18, 2011Date of Patent: July 22, 2014Assignee: Microsoft CorporationInventors: John Tardif, Seshagiri Panchapagesan

Patent number: 7450162Abstract: A digital camera 10 includes a CCD imager 14. When an interval photographing or an animation photographing is selected, an object is photographed by the CCD imager 14 for a plurality of times, and compressed image data is generated each photographing by each photographing. The generated compressed image data is stored in a temporary area of an magnetooptical disk 42. Upon completion of photographing the desired number of frames, the generated respective compressed image data are converted into a moving image file, and moved to a proper recording area of the magnetooptical disk 42. Frame rate information is written in the moving image file. Upon reproducing, firstly, the frame rate information is detected, the compressed image data of each frame is reproduced in accordance with this information. The moving image that moves at a desired speed is displayed on a monitor 30.Type: GrantFiled: April 9, 2001Date of Patent: November 11, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Masahiro Shioji, Junya Kaku

Patent number: 6456795Abstract: In a multifunction camera, an area selector is used both as an operation key in a first selection mode for selecting the focus detection area of the focus detection device, and as an operation key in a second selection mode for selecting the function setting of the camera. A mode selector is provided which is settable at three positions including a local position, wide position, and lock position. The focus detection area selected at the local position is locked when the mode selector is set at the lock position and has been moved from the local position to the lock position, whereas the wide position is locked when the mode selector has been moved from the wide position to the lock position.Type: GrantFiled: August 20, 2001Date of Patent: September 24, 2002Assignee: Minolta Co., Ltd.Inventors: Junko Nagahata, Hiroshi Ueda, Akihiko Fujino, Rika Noguchi, Tatsuya Suzuki

Patent number: 6295415Abstract: A camera having a magnetic recording circuit for recording information in a magnetic recording part of a film at each of photographing frames of the film is arranged such that, in an automatic exposure bracketing mode or an AE lock mode, information indicating that printing be performed under the same condition is recorded at each of the frames photographed in the above-stated mode.Type: GrantFiled: May 29, 1996Date of Patent: September 25, 2001Assignee: Canon Kabushiki KaishaInventors: Ritsuo Kashiyama, Toshifumi Ohsawa

Patent number: 6144804Abstract: A camera which has a visual line detection device to detect the visual line of a photographer, and which inhibits visual line detection and automatic focus adjustment operations when these operations are unnecessary. Visual line detection may be inhibited, for example, when a manual focus lens is used in the camera, or when a self-timer mode is being used and the photographer is not observing the camera viewfinder. In these types of situations, the visual line detection, focus detection region selection based upon the visual line detection result and focus adjustment action based upon the visual line detection result are inhibited, thereby preventing useless consumption of electric power, and preventing focusing on undesired objects.Type: GrantFiled: March 25, 1996Date of Patent: November 7, 2000Assignee: Nikon CorporationInventor: Hideya Inoue

Patent number: 5832321Abstract: In a camera of the present invention, when a shutter button is depressed half, a focusing and a photometry are executed. If the shutter button is held in a state of being depressed half, the results are retained. In this case, if an MF button is depressed, the photometry result is retained while the MF button 48 is being depressed, even if the shutter button is released. When the shutter button is depressed half again, only the photometry is performed.Type: GrantFiled: June 28, 1996Date of Patent: November 3, 1998Assignee: Fuji Photo Optical Co., Ltd.Inventors: Tatsuo Saito, Shigenori Goto
