  • Patent number: 11082617
    Abstract: An electronic device includes a power supply and a power supply circuit. The power supply circuit is configured to alternately switch a state of the electronic device between a first state to supply power to another device and a second state to receive power from said another device, and stop a switching operation of the state of the electronic device when the electronic device is off, to fix the state of the electronic device to one of the first state and the second state.

  • Patent number: 10484607
    Abstract: A shake correction control device includes circuitry to control an ON/OFF timing of horizontal synchronizing signals of an image capture element, and an ON/OFF timing of one or more drive signals used for correcting a shake of the image capture element, shift at least one of the ON/OFF timing of the drive signals used for correcting the shake of the image capture element so as to be out of a period of time during which analog/digital (A/D) conversion processing is collectively performed on pixel signals for one or more horizontal lines of the image capture element, and adjust the at least one of the ON/OFF timing of the drive signals used for correcting the shake of the image capture element with respect to the horizontal synchronizing signals based on the number of the one or more horizontal lines of the pixel signals collectively subjected to the A/D conversion processing.

  • Patent number: 9544502
    Abstract: A dark exposure control device comprises a dark exposure performing processor, an aperture-stop, and an aperture-stop driving processor. The dark exposure performing processor detects an image signal generated by an imaging device while the shutter is closed. The aperture-stop adjusts the amount of light incident on the imaging device. The aperture-stop driving processor adjusts the opening degree of the aperture-stop to smaller than the opening degree set for a main exposure while the dark exposure performing processor is operated.

  • Patent number: 8848071
    Abstract: An imaging apparatus capable of capturing a moving image with an imaging device is equipped with a first image-processing device that uses hardware to process images captured by the imaging device and a second image-processing device that processes captured images with software. The imaging apparatus includes an image-processing switching device that selectively operates one of either the first image-processing device or the second image-processing device. The imaging apparatus includes a light-detection device that detects the amount of light received by the imaging device and a sensitivity adjustment device that increases the sensitivity of the imaging device as the amount of light decreases. The image-processing switching device operates the first image-processing device when the sensitivity is lower than a predetermined value and operates the second image-processing device when the sensitivity is higher than the predetermined value.

  • Patent number: 8681231
    Abstract: A camera according to the present invention is equipped with an image sensor; an A/D converter that converts analog image-pixel signals read from the image sensor to digital image-pixel signals; an image stabilizer that comprises a coil and a movable member configured to move in a given direction while supporting the image sensor; an image stabilization controller that controls a position of the movable member at given time intervals by sending pulse drive signals through the coil; and a timing adjustment processor that shifts at least one of a rise timing and fall timing of the pulse drive signals from a signal-processing interval associated with an A/D conversion process.
