  • Publication number: 20200412903
    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.

  • Publication number: 20200186737
    Abstract: A photoelectric conversion element includes pixels that receive light and each generate charge in response to light incidence. The pixels include a first pixel that performs a first readout operation to read a reset signal and an optical signal and a second pixel on which a readout operation is performed at the same time as that of the first pixel and that performs selectively either the first readout operation or a second readout operation to read the reset signal. The photoelectric conversion element further includes, in association with each pixel, a first holding unit that holds the reset signal and the optical signal, and a first switch that controls writing to the first holding unit. A control line that controls the first switch associated with the first pixel and a control line that controls the first switch associated with the second pixel are formed of separate wirings.
