  • Publication number: 20130341750
    Abstract: There is provided a solid-state imaging device including a plurality of pixels which are arranged in a two-dimensional array form and in each of which color separation is performed in a substrate depth direction. The solid-state imaging device includes a pixel addition section which performs addition, when pixel signals of the plurality of pixels are added up to be outputted, by setting addition regions of pixel signals of a first color component to be shifted from addition regions of pixel signals of a second color component at regular intervals.

  • Patent number: 8115153
    Abstract: A solid-state imaging device which includes a pixel unit, a plurality of pixels in the pixel unit which are two dimensionally arranged in rows and columns and each include a photoelectric conversion element and a reset element, a driver unit which sequentially applies selective scanning to each respective row of the pixel unit, a mode switching circuit, where the mode switching circuit is configured to charge a portion of the pixels in the pixel unit and to apply an intermediate voltage to a gate of each reset element in the non-charged pixels.

  • Patent number: 8023018
    Abstract: A solid-state imaging device having: (a) a pixel array with an oblique pixel pattern in which pixels are obliquely disposed, an odd-numbered row vertical signal line in an odd-numbered row vertical signal line group being connected to each column of odd-numbered row pixels and an even-numbered row vertical signal line in an even-numbered row vertical signal line group being connected to each column of even-numbered row pixels; (b) a row selector for separately selecting an odd-numbered row and an even-numbered row of the oblique pixel pattern; (c) an odd-numbered row column processing circuit group including column processing circuits and connected to the odd-numbered row vertical signal line group, for adding signals of the odd-numbered row pixels between columns; (d) an even-numbered row column processing circuit group including column processing circuits and connected to the even-numbered row vertical signal line group, for adding signals of the even-numbered row pixels in pixel columns; and (d) a column s

  • Patent number: 7570290
    Abstract: A drive method for a solid-state imaging device having an oblique pixel pattern includes the steps of: adding, separately for an odd-numbered row and an even-numbered row, x pixels in the horizontal direction and y pixels in the vertical direction, the x pixels and the y pixels having the same color, in an area having adjacent n pixels in the horizontal direction and adjacent n pixels in the vertical direction, where n is an odd number of three or greater and n?x?y; and repeatedly adding the x pixels and the y pixels while shifting the n×n area by m pixels in the vertical or horizontal direction, where m is an odd number of three or greater. The n×n area of odd-numbered rows is displaced from that of even-numbered rows by m pixels in the oblique direction in the oblique pixel pattern.

  • Patent number: 7550704
    Abstract: A solid state imaging device includes: a pixel array section in which pixels including photoelectric conversion elements are two dimensionally arranged; a vertical selector that sequentially applies selective scanning to respective rows of the pixel array section; and a controller that discharges, when a mode for reading out only pixel signals of respective rows in a given row range in the pixel array section is set by the vertical selector, charges generated in the photoelectric conversion elements in respective pixels of rows outside the row range to a pixel power supply.
