  • Patent number: 7755703
    Abstract: A signal processing circuit generates an image signal by performing signal processing to an imaging signal obtained through a picked up optical system that includes a lens, a diaphragm, an image sensor, and a lens barrel. A main light source detector detects a main light source contained in a picked up image of the image signal. An estimated ghost generator generates an estimated ghost based on layout information of the main light source and the imaging optical system, and structural information of the lens barrel. A matching device extracts an estimated ghost image by searching the estimated ghost in the picked up image through pattern matching. A ghost subtractor subtracts the estimated ghost image from the picked up image.

  • Patent number: 7457486
    Abstract: 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.

  • Patent number: 7358475
    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.

  • Patent number: 7349016
    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.
