  • Publication number: 20230217137
    Abstract: A photoelectric conversion device includes a pixel, the pixel including an avalanche photodiode, and a signal processing circuit including a counter configured to generate a count value based on a photon incident on the avalanche photodiode during a count period, the signal processing circuit being configured to output the count value for each count period repeatedly. The pixel transitions from a first state to a second state in which a length of the count period is shorter than that in the first state in accordance with a result of determination based on the count value and a predetermined threshold value.

  • Publication number: 20220246661
    Abstract: A photoelectric conversion apparatus includes a first substrate having a pixel area, a second substrate disposed in a multilayer structure on the first substrate, and a heat dissipation structure. The second substrate includes a processing unit configured to execute a machine learning process on an image signal output from the pixel area. The heat dissipation structure is disposed in a region adjacent to or in a region overlapping the processing unit when seen in a plan view, the processing unit. The heat dissipation structure is formed on the first or second substrate by a semiconductor active region, polysilicon, a structure including a metal connection part, a TSV structure, or a cavity structure, or the heat dissipation structure is attached to the first substrate in an area other than the pixel area. When the structure is formed on the first substrate, it is electrically connected to the second substrate.

  • Patent number: 11363159
    Abstract: In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a “mixture of colors” occurs. A “mixture of colors” occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element. In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.
