摘要： A pixel area of a megapixel solid-state color imaging device is divided into unit areas for pixel adding and all the pixels for the same color are added together in each unit area. Accordingly, the percentage of utilized pixels is raised to 100% and aliasing noise to low frequencies in a high-frequency video signal is greatly suppressed by a spatial LPF (low pass filter) effect of the pixel addition in the area units.

摘要： An imaging element includes a photoelectric conversion element, a readout transistor, an accumulated element, a detection transistor, and a reset transistor. The readout transistor reads a signal charge when a gate potential to be supplied to the gate terminal is changed from a first state to a second state. The detection transistor detects a voltage signal after the gate potential to be supplied to the gate terminal of the readout transistor is changed from the second state to the first state. A reset potential supplied from the reset transistor to the accumulated element has an intermediate potential between the gate potential in the first state that is supplied to the gate terminal of the readout transistor and a predetermined VDD potential.

摘要： A solid-state imaging element includes photoelectric conversion elements having a complementary or Bayer color filter array. The solid-state imaging element adds together electric charges stored in nine photoelectric conversion elements having color filters of one of multiple colors in each portion of six rows and six columns, to obtain a resulting electric charge, and outputs the resulting electric charge as one pixel. A portion for one of the colors deviates from a portion for each of the other colors by three rows and/or three columns. This pixel-addition operation produces an effect of a spatial low pass filter, thereby reducing signal components exceeding a Nyquist frequency corresponding to a target resolution. Consequently, aliasing noise in an image with the target resolution is reduced, and therefore higher image quality can be achieved, when compared with a conventional resolution reduction technique.
