Title:
SOLID-STATE IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2007251352
Kind Code:
A
Abstract:

To provide a solid-state imaging device that improves image deterioration, such as color mixture and deviation in white balance corresponding to photographic conditions.

In the solid-state image pickup device 10, an output system determination part 50 determines an output system, such as the number of operations of output circuits 74, 76 and a drive frequency of one or more horizontal transfer paths 72 in an imaging part 20 corresponding to the photographic conditions, such as a photographic mode and a sensitivity mode. A plurality of vertical transfer paths 78, one or more horizontal transfer paths 72, and a plurality of the output circuits 74, 76 in the imaging part 20, are drivingly controlled, corresponding to the output system so as to generate an image electrical signal 116 by reducing a transfer speed of the one or more horizontal transfer paths 72, while dividing one imaging screen of an imaging face 20, as required. Since the output system determination part 50 determines the output system comprising the number of operations more than normal and a drive frequency lower than normal in the high-sensitivity mode, an image that does not generate deterioration, such as color mixture can be generated, while avoiding transfer deterioration, by raising the horizontal transfer efficiency without damaging high-speed performance.
