  • Publication number: 20240107190
    Abstract: An analog-to-digital converter comprises: an analog-to-digital conversion unit that performs analog-to-digital conversion using ?? modulation on an image signal output from pixels; a setting unit that sets an operating frequency of the analog-to-digital conversion unit; and a generation unit that generates a clock signal having the operating frequency and supplies it to the analog-to-digital conversion unit. The setting unit sets the operating frequency based on at least one of a digital gain to be applied to the signal output from the analog-to-digital conversion unit and a shooting mode.

  • Publication number: 20240106454
    Abstract: An apparatus comprises: a plurality of analog-to-digital conversion units that performs analog-to-digital conversion using ?? modulation by comparing a signal output from a plurality of pixels to a reference voltage; and a plurality of supply units that supply one of a plurality of different reference voltages to each of the plurality of analog-to-digital conversion units. The plurality of supply units supply different reference voltages to adjacent analog-to-digital conversion units among the plurality of analog-to-digital conversion units.

  • Patent number: 11838630
    Abstract: An apparatus includes a capturing device configured to capture an image of a subject; an estimation unit configured to estimate, from the captured image of the subject, a speed of the subject at a time point of image capture of a subsequent image, the estimation being performed using a learned model generated through machine learning, and a control unit configured to, based on the estimated speed of the subject, control an image capturing operation for the image capture of the subsequent image by the capturing device.

  • Patent number: 4646533
    Abstract: In a refrigerating apparatus comprising a rotary compressor, a pressure-controlled valve is inserted in a path between a condenser and an evaporator and a reverse flow check valve is inserted between the evaporator and a suction line connected to the input port of the rotary compressor, thereby to eliminate undesirable heat load caused by undesirable flow-in of the refrigerant gas into the evaporator after the rotary compressor stops.
