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 an accumulation period to be shorter in combination mode than in individual mode (see Vsub in each mode in FIG. 6).

摘要： A driving method is applied to a solid-state imaging apparatus having photoelectric conversion portions, transfer portion for reading out signal charges, and an excess charge draining portion for draining charges exceeding a saturation charge amount that is set by a reference voltage. One of driving modes is selected from a full pixel mode in which accumulated signal charges are detected individually for each pixel and a pixel mixing mode in which signal charges of a predetermined number of pixels are mixed to be detected. In the full pixel mode, the draining portion is supplied with the reference voltage having the same value during a charge accumulation period and a read transfer period for read transferring charges. In the pixel mixing mode, the draining portion is supplied with the reference voltage having a low level during the charge accumulation period and the reference voltage having a high level during the read transfer period. An appropriate driving for the pixel mixing mode can be performed by avoiding a limitation of a substrate voltage, without deteriorating the spectral characteristics, the sensitivity, nor the linearity.

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.
