  • Publication number: 20250008236
    Abstract: A conversion apparatus includes a pixel array unit in which a plurality of first pixels that generates gradation signals indicating amounts of incident light and a plurality of second pixels that generates event signals are two-dimensionally disposed, a reading unit configured to read the gradation signals and the event signals from the pixel array unit, and a control unit configured to change an output data rate of the gradation signals and an output data rate of the event signals, wherein a first pattern for outputting the gradation signals at a first output data rate and outputting the event signals at a second output data rate and a second pattern for outputting the gradation signals at a third output data rate different from the first output data rate and outputting the event signals at a fourth output data rate different from the second output data rate are switched.

  • Publication number: 20240312210
    Abstract: An imaging device includes a pixel portion that includes a plurality of unit pixels and is configured to detect as an event signal a change in a light intensity of each of the unit pixels, an event readout portion configured to read out the event signal from the pixel portion, an output portion configured to output, regarding at least one region relating to the event signal of the pixel portion, motion information relating to motion of the at least one region, and a determination portion configured to determine a predicted region after a change in the at least one region, the predicted region being predicted based on the motion information. The event readout portion is configured to read out the event signal from a unit pixel included in the determined predicted region.

  • 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.
