  • Patent number: 11900571
    Abstract: For example, in order to enable an RCCB sensor or a specific optical system to perform an appropriate image correction process (distortion correction and the like), an imaging device includes an imaging element, an optical system configured to form an image on an imaging surface of the imaging element and has a characteristic in which an image formation magnification differs depending on a position in the imaging surface, a demosaic unit configured to generate color image data of at least two colors from the data output from the imaging element, and a distortion correction unit configured to correct distortion of the color image data of at least two colors generated by the demosaic unit.
    Type: Grant

  • Patent number: 10281979
    Abstract: With respect to images captured by cameras, content of which changes as time passes, an information processing apparatus determines an evaluation value with respect to content at each given time of the images according to a predetermined standard, and switches and displays an image on a display apparatus by selecting a camera image having a high evaluation value, while heightening an evaluation value of the camera image currently selected and displayed on the display apparatus for a predetermined period of time in order to prevent the image from being switched frequently.

  • Publication number: 20130329068
    Abstract: In the case of a conventional image apparatus that generates refocus image on the occasion of image display, there is a waiting time because the image apparatus generates the refocus image in response to an operation of a user and requires the time to generate the refocus image. To address this situation, an image apparatus determines ranks of targets to be in focus based on history information indicating operation history, and generates sequentially combined image data from multi-viewpoint image data obtained by capturing images from multiple viewpoints, by focusing on the targets in accordance with the determined ranks.

  • Publication number: 20040004179
    Abstract: A temperature compensating circuit includes a first circuit network 1 between an inverting input terminal of an operational amplifier 13 and an output terminal of the operational amplifier 13, and a second circuit network 2 between the inverting input terminal of the operational amplifier 13 and a reference potential. At least one of the first circuit network and the second circuit network is made of an arrangement containing a plurality of series-connected thermistor/resistor pairs in which the thermistors are connected parallel to the resistors, and the temperature compensating circuit compensates a temperature-dependent signal which is inputted into a positive phase input terminal of the operational amplifier 13, and outputs the temperature-compensated signal.
