摘要： Random pollution of output signals with logic noise caused by video signal processing is prevented and a high quality image video signal with reduced random noise is output. A signal processor includes a digital signal processor (DSP) which processes a digital signal resulting from analog to digital conversion of an analog signal stored in a pixel unit, an output circuit which outputs a signal resulting from signal processing by the DSP, and line memory which is disposed between the output circuit and the DSP and stores a digital signal output from the DSP for a shorter period than the horizontal scanning period. The output circuit reads the signal stored in the line memory in sync with the beginning of a read-out timing in the horizontal scanning period.

摘要： In a pixel unit, cells are arranged in rows and columns two-dimensionally. Each of the cells accumulates signal charge obtained by photoelectrically converting light incident on photoelectric conversion section and outputs a voltage corresponding to the accumulated signal charge. On the cells, W, R, G, and B color filters are provided. Analog signals output from the W pixel, R pixel, G pixel, and B pixel are converted into digital signals by an analog/digital converter circuit, which outputs a W signal, an R signal, a G signal, and a B signal separately. A W signal saturated signal quantity is controlled by a saturated signal quantity control circuit. Then, a signal generator circuit corrects the R signal, the G signal, and the B signal using the W signal, the R signal, the G signal, and B signal output from the analog/digital converter circuit and outputs the corrected R, G, and B signals.

摘要： A pixel section outputs R, G and B signals which are obtained by photoelectrically converting light incident on R, G and B pixels. An adding section determines a prescribed area in which a certain pixel is set as a central pixel, and adds the R, G and B signals from the central pixel and peripheral pixels arranged on the periphery of the central pixel in the prescribed area in order to produce an addition signal. A ratio calculating section calculates an average value of each of the R, G and B signals, and a ratio coefficient of the average value of each of the R, G and B signals to a total value of the average values. An RGB generating section generates a new R signal, G signal and B signal by using the addition signal and the ratio coefficients calculated by the ratio calculating section.

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.
