  • Patent number: 11778153
    Abstract: An imaging device is provided. The device comprises: an imaging unit in which a plurality of pixels each including a photoelectric conversion element are arranged; a signal processor configured to process a signal output from the imaging unit; and a storage device configured to store the signal output from the imaging unit and transfer the signal to the signal processor. The storage device stores a plurality of image signals output by the plurality of pixels arranged in the imaging unit as a plurality of sub-frames and then outputs a sub-frame satisfying a predetermined condition out of the plurality of sub-frames as a signal for configuring a single frame.

  • Patent number: 11159754
    Abstract: An imaging device includes an image pickup device having pixels and a correction processing unit that corrects signals output from the image pickup device, the pixels include a visible light pixel that receives light corresponding to a visible light wavelength range and an infrared light pixel that is arranged adjacent to the visible light pixel and receives light corresponding to an infrared wavelength range, and the correction processing unit includes a calculation unit that performs a first process of reducing, from a signal of the infrared light pixel, a component in the pixel signal of the infrared light pixel and based on an inflow amount of charges to the infrared light pixel from another pixel adjacent to the infrared light pixel and a second process of obtaining a signal corresponding to a difference between pixel signals of the visible light pixel and the infrared light pixel after the first process.

  • Patent number: 10972694
    Abstract: An imaging apparatus includes a pixel unit having a plurality of pixels, a signal processing unit that generates image data by performing signal processing on a pixel signal read from the pixel unit and outputs the image data on a frame basis, an information generation unit that generates time information on a frame basis, and an output unit that outputs the time information associated with one frame before the image data of the one frame is output from the signal processing unit and outputs the image data of the one frame after an end of the output of the time information ends.
