Abstract: A solid-state imaging device includes pixels 2 arranged two-dimensionally on a semiconductor substrate 1. In a predetermined area in each pixel is formed a light-sensitive area 3 for receiving incident light 11, and each pixel includes a photoelectric conversion portion 4 for converting the incident light into a signal charge. In at least some of the pixels, the center of the light-sensitive area is offset from the center of the pixel when seen from directly above a principal surface of the semiconductor substrate. Each pixel further includes a light-path change member 12a and 12b for deflecting incident light traveling toward the center of the pixel so as to be directed toward the center of the light-sensitive area. Thus, a solid-state imaging device simultaneously realizing the miniaturization of pixels and a high image quality is provided.

Abstract: 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.

Abstract: A color filter arrangement (11) is used, in which a plurality of filter units are each made of 2×2 arrangements of red (R), green (G), green (G) and blue (B) color elements. First, signal charges are added up for all pixels belonging to each of a plurality of pixel blocks made of quadratic arrangements of 3×3 of pixels, which are larger than the filter units (2×2 arrangement). Then, compressed color information for each of the pixel blocks is obtained from a result of the addition for each pixel block, taking the 2×2 arrangements of pixel blocks as large filter units.

Abstract: A solid-state image sensor includes photoelectric converters positioned either in a complementary color filter array or in the Bayer color filter array. The solid-state image sensor either adds together electric charges obtained by 9 photoelectric converters that relate to one color in each portion of six rows and six columns of the photoelectric converters so as to output a resulting electric charge as one pixel, or outputs the electric charges obtained by 9 photoelectric converters that relate to one color as 9 pixels without added together. By adding together the electric charges, the resolution of an image becomes one ninth of the case where the electric charges are not added together, and the sensitivity becomes 9 times higher than the same. The control unit not shown in the drawing determines a time length for photoelectric conversion assuming that the electric charges are not added together. If the determined time length is longer than a predetermined threshold, the actual time length for photoelectric conversion is reduced to {fraction (1/9)} of the determined time length, and an image is generated based on the resulting electric charges that are outputted after the electric charges stored in the photoelectric converters are added together.
