Patent number: 7630107Abstract: A setting for white balance used by a camera during image-capturing can be reflected in a printer, thereby preventing, during printing, execution of such correction as negates an atmosphere of a light source in a recorded image in which the atmosphere has been intentionally allowed to remain. A camera used for a system of the present invention is a digital camera having a white balance process function of allowing the atmosphere of a photographing light source to remain in an image. During image-capturing, WB adaptation rate information indicative of a level of white balance correction is recorded on a recording medium as additional information. A printer reads the WB adaptation rate information for the camera via the recording medium to control white balance in accordance with the setting for the WB adaptation rate. For example, if the WB adaptation rate is less than 100%, then an AWB process executed by the printer is turned off to print the recorded image without changing its tints.Type: GrantFiled: October 25, 2005Date of Patent: December 8, 2009Assignee: FUJIFILM CorporationInventors: Koji Ichikawa, Koichi Sakamoto, Masahiko Sugimoto, Hiroshi Tanaka

Patent number: 7570883Abstract: An image pickup apparatus includes an automatic exposure controller automatically controls ISO sensitivity in response to the output signal of an exposure metering circuit, and controls the exposure so that exposure setting is determined based on the brightness values of both the central photometry area and the remaining photometry area of an imaging frame. The automatic exposure controller controls the exposure setting so that when the ISO sensitivity is set to its higher value, the weighting factor of the central photometry area is higher than that of the remaining photometry area. The automatic exposure controller further determines whether or not a light source is behind an object, and, if it is the case, reduces the adjusted exposure setting so as to increase the amount of light incident on the image pickup apparatus.Type: GrantFiled: March 21, 2007Date of Patent: August 4, 2009Assignee: Fujifilm CorporationInventor: Koichi Sakamoto

Patent number: 7400355Abstract: A received light quantity detection device where high-sensitivity pixels and low-sensitivity pixels are formed is used for photometry. It is possible to perform measurement over the low range (for example, 0[EV] through 8[EV]with a single occasion of photometry. In the case that both the high-sensitivity pixels and the low-sensitivity pixels are saturated, it is possible to perform further measurement over the high range (for example, 8[EV] through 16[EV]) by narrowing the aperture or increasing the electronic shutter speed for retried photometry with a retried photometry. This reduces the time required to calculate a correct exposure value on image pickup apparatus such as a camera.Type: GrantFiled: July 15, 2003Date of Patent: July 15, 2008Assignee: Fujifilm CorporationInventors: Masaya Tamaru, Masahiko Sugimoto, Koichi Sakamoto, Manabu Hyodo, Kazuhiko Takemura, Koji Ichikawa
