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.
