摘要： Gray level data of boundary pixels that are adjacent to a block boundary in a photoelectric conversion section is stored. Then, a cumulative histogram regarding the number of pixels for different gray levels is produced based on the stored gray level data separately for each block, and a data table representing the correspondence between each gray level before correction and that after correction for the block to be corrected is produced so as to reduce the difference between the cumulative histograms. The data table is stored in a correction data RAM. By using the data table, the outputs of the block to be corrected are non-linearly corrected for different gray levels.

摘要： 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.

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.

摘要： A drive unit 120 sets a saturation amount in a read period in which charges generated in pixels are read to vertical CCDs to be lower in a combination mode than in an individual mode (see Vsub in count values 22 to 24 in FIG. 6). As a result, excess charges in the pixels are drained to an n-type substrate 11. The drive unit 120 also sets al accumulation period to be shorter in combination mode than in individual mode (see Vsub in each mode in FIG. 6).

摘要： 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.

摘要： An image pickup area including a plurality of pixels arranged in a two-dimensional matrix pattern, each pixel being an amplified MOS image sensor, is divided into a block A including odd-numbered columns of pixels and a block B including even-numbered columns of pixels. A horizontal signal line and an output amplifier are provided for each of the block A and the block B. Signal voltages on vertical signal lines are temporarily stored in a line memory. In the normal mode, the signal voltages of two pixels adjacent to each other in the horizontal direction are supplied from the line memory respectively to the output amplifiers. In the correction mode, a switch is closed to connect the horizontal signal lines with each other so that the signal voltage of the same pixel is supplied to the output amplifiers.
