摘要： In a CMOS image sensor, current leakage after a series of noise removing operations has been completed is suppressed in a read operation for each horizontal line, thereby suppressing image noise occurring on the output display screen of the image sensor. There are provided signal storage regions for storing the signals read from the unit cells in the same row selected in the imaging area onto vertical signal lines and horizontal select transistors for sequentially selecting and reading the signals stored in the individual signal storage regions and transferring them to read horizontal signal lines. At least in the period during which the signals are read from the signal storage regions, one of the drain and source of the transistor electrically connected to the signal path between the vertical signal line and horizontal signal line is biased in the reverse direction with respect to the substrate region. Two adjacent ones of the horizontal select transistors form a pair. The horizontal select transistors in each pair share one of the source/drain regions so as to be connected to the horizontal signal line in common, and the others of the source/drain regions are connected to the vertical signal line individually.

摘要： In a pixel unit, W, R, G, and B pixels are arranged in rows and columns. The pixel unit output W, R, G, and B signals obtained by photoelectrically converting light incident on the W, R, G, and B pixels. An edge detection unit determines a specific area having a W pixel provided with a white filter as a central pixel in the pixel unit, divides the specific area into blocks including the central pixel, and detects edge information as to whether there is an edge of an image in each of the blocks. A block select unit selects a block with no edge from the edge information. A ratio calculating unit calculates the ratio coefficients of the R, G, and B signals from the selected block. An RGB signal generator generates new R, G, and B signals from the W signal of the central pixel using the ratio coefficients.
