摘要： The imaging device includes a pixel including a photoelectric converter, an output line, a readout circuit unit connected to the output line, and a control unit. The readout circuit unit includes an amplifier circuit, a first switch for resetting the amplifier circuit, a sample-and-hold circuit, a second switch provided between the amplifier circuit and the sample-and-hold circuit, and a gain switching circuit. The control unit performs a first period of resetting the amplifier circuit by first switch, and a second period of connecting the amplifier circuit and the sample-and-hold circuit by the second switch. The first and second periods at least partially overlap with each other, and a timing at which the second switch transitions from an on state to an off state in the second period is later than a timing at which the first switch transitions from an on state to an off state in the first period.

摘要： An image sensor may include an image sensor pixel array, row control circuitry, and column readout circuitry. The array may include first and second sets of active pixels that are configured in different manners or controlled by the row control circuitry and column readout circuitry in different manners. The array may include optically black pixels that have photosensitive elements shield from incident light. The optically black pixels may be configured to generate first and second sets of black level signals adapted to both the first and second sets of active pixels. The corresponding sets of black level signals may be used to better reduce noise in corresponding sets of image signals generated by the first and second sets of active pixels.

摘要： A method and system for acquiring data from a pixelated image sensor for detecting charged particles. The method includes reading a pixel voltage of one or more of the multiple pixels multiple times without resetting the image sensor and digitizing the pixel into a first number of bits. The camera outputs a digitized compressed pixel voltage in a second, less, number of bits. The maximum range of the digitized compressed pixel voltage is less than a maximum range of the pixel voltage.

摘要： The present disclosure relates to a solid-state imaging device, a method for manufacturing the same, and an electronic apparatus capable of improving sensitivity while suppressing degradation of color mixture. The solid-state imaging device includes an anti-reflection portion having a moth-eye structure provided on a boundary surface on a light-receiving surface side of a photoelectric conversion region of each pixel arranged two-dimensionally, and an inter-pixel light-blocking portion provided below the boundary surface of the anti-reflection portion to block incident light. In addition, the photoelectric conversion region is a semiconductor region, and the inter-pixel light-blocking portion has a trench structure obtained by digging the semiconductor region in a depth direction at a pixel boundary. The techniques according to the present disclosure can be applied to, for example, a solid-state imaging device of a rear surface irradiation type.
