Publication number: 20070177050Abstract: An exposure control apparatus for controlling an exposure adjustment mechanism on the basis of a captured image signal includes the following elements. A face detecting unit detects a face of a person appearing in a captured image on the basis of the captured image signal. A histogram data determining unit determines histogram data by setting a face detection region in the captured image according to detection information and detecting at least a brightness value of the face detection region from the captured image signal. A target brightness setting unit sets a target brightness range for desired brightness of the face. An exposure control amount determining unit determines, when a face is detected, an amount of control for the exposure adjustment mechanism by comparing the target brightness range with a brightness value at a peak of the histogram data or a brightness region in the vicinity of the peak.Type: ApplicationFiled: January 25, 2007Publication date: August 2, 2007Applicant: Sony CorporationInventors: Ruihua Xiao, Akira Shiga

Patent number: 7145602Abstract: An apparatus and method for controlling exposure of a digital camera with high precision by setting a proper exposure amount by emitting auxiliary light during auto-focusing, detecting the luminance level of an object, and carrying out an exposure controlling operation. The apparatus detects the luminance level of an object in an AE frame under the outside light prior to emitting the auxiliary light, and detects again the luminance level of the object in an AF frame under the auxiliary light after emitting the auxiliary light. The apparatus further performs an exposure controlling operation based on the luminance level in the AE frame when it has been determined that the exposure amount of the AF frame has increased markedly in a determining step, or based on the luminance level in the AF frame when it has been determined that the exposure amount of the AF frame has not increased markedly in the determining step.Type: GrantFiled: June 20, 2002Date of Patent: December 5, 2006Assignee: Sony CorporationInventor: Akira Shiga

Publication number: 20050062874Abstract: A digital camera with reduced shutter lag and improved exposure accuracy, and including image pickup lens optics, an iris, an image pickup, a hold/gain control circuit, a luminance level detector, an exposure control circuit, and a control circuit. The exposure control circuit discriminates, based on a luminance level supplied from the luminance level detector, whether or not appropriate exposure is performed. Then, based on the discrimination result, the exposure control circuit arithmetically operates three values of numerical aperture of the iris, shutter speed of an electronic shutter of the image pickup, and gain of the hold/gain control circuit, which are necessary for appropriate exposure. The exposure control circuit arithmetically operates iris control data, electronic shutter control data, and gain control data necessary for the arithmetically operated exposure amounts to be individually reflected on the iris, the electronic shutter of the image pickup, and the hold/gain control circuit.Type: ApplicationFiled: September 25, 2003Publication date: March 24, 2005Inventors: Akira Shiga, Toshinori Orito

Publication number: 20040116952Abstract: A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated using the secondary battery as a driving power source and used to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument held in noncontact with the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged while left clean.Type: ApplicationFiled: December 3, 2003Publication date: June 17, 2004Applicant: Olympus Optical Co., Ltd.Inventors: Tomohisa Sakurai, Shinji Hatta, Akira Shiga, Tsuyoshi Tsukagoshi, Koji Yasunaga, Masaru Karasawa, Hiroyuki Sangu, Takeaki Nakamura
