Patent number: 9615031Abstract: An imaging unit is configured to capture images of a subject. A sensor is configured to detect brightness. A first detector is configured to detect whether or not a period during which a predetermined brightness has been detected by the sensor continues for a first period of time. A second detector is configured to detect whether or not a period during which the predetermined brightness has been detected by the sensor continues for a second period of time shorter than the first period of time. A determiner is configured to determine a circumstance where the imaging unit captures images of the subject in a daytime in a specific state where light is temporarily cut off, based on a first detection result by the first detector and a second detection result by the second detector.Type: GrantFiled: August 25, 2015Date of Patent: April 4, 2017Assignee: JVC KENWOOD CORPORATIONInventors: Hidehiro Katoh, Takashi Sueda

Patent number: 8072505Abstract: Light from an object is converted by an imaging device into an electric signal carrying an object image. A video signal is generated by a video signal processor based on the electric signal. A human face is detected by a face detector if a human is contained in the image, based on the video signal. An on-screen signal is generated by an on-screen generator for either a first or a second menu window each for use in selection among imaging modes. The first and second windows are used when no face and the face is being detected, respectively. The on-screen signal is supplied to a screen which displays one of the windows. The generator is controlled by a controller based on information, supplied by the detector, indicating whether the face is contained in the image, so that the on-screen signal is generated for the first or the second window.Type: GrantFiled: July 15, 2009Date of Patent: December 6, 2011Assignee: Victor Company of Japan, Ltd.Inventors: Atsushi Sugita, Hidehiro Katoh

Patent number: 7525572Abstract: A shake sensor outputs an analog shake detection signal representative of a shake of a camera body. An amplifier operates for amplifying the analog shake detection signal to generate an analog amplification-resultant signal. The analog shake detection signal and the analog amplification-resultant signal are converted into a digital shake detection signal and a first digital amplification-resultant signal, respectively. A signal value represented by the digital shake detection signal is amplified on a digital basis to generate a second digital amplification-resultant signal. A decision is made as to whether or not the signal value represented by the first digital amplification-resultant signal remains greater than a predetermined reference value during at least a prescribed time interval. One is selected from the first and second digital amplification-resultant signals in response to the result of the decision. A shake corrective signal is generated in response to the selected signal.Type: GrantFiled: March 22, 2004Date of Patent: April 28, 2009Assignee: Victor Company of Japan, Ltd.Inventors: Hidehiro Katoh, Yutaka Ichinoi
