Solid-state imaging device, method for driving the same, and imaging device

A method for driving a solid-state imaging device comprising:

• reading a first signal corresponding to physical quantities, which have been accumulated in a first accumulation time, of pixels in a first pixel group among pixels which detect physical quantities and which are two-dimensionally arranged in a matrix in a pixel array unit;
• and
• reading a second signal corresponding to physical quantities, which have been accumulated in a second accumulation time which is shorter than the first accumulation time, of pixels of a second pixel group comprising pixels which are arranged adjacent to the pixels of the first pixel group,
• wherein,
• said reading of the physical quantities of the pixels in the second pixel group occurs in a beginning of the first accumulation time, said first and second signals read in a same frame;
• and
• a number of pixels in at least one of the first pixel group and the second pixel group is greater than a number of pixels in a pixel row.

An imaging device comprising:

• a pixel array unit in which pixels which detect physical quantities are two-dimensionally arranged in a matrix;
• a driving portion reading physical quantities, which have been accumulated in a first accumulation time, of pixels of a first pixel group among the pixels included in the pixel array unit,
• the driving portion further reading physical quantities, which have been accumulated in a second accumulation time which is shorter than the first accumulation time, of pixels of a second pixel group which are adjacent to the pixels of the first pixel group, wherein said reading of the physical quantities of the pixels in the second pixel group occurs in a beginning of the first accumulation time, said first and second pixel groups read in a same frame;
• and
• a signal processing portion configured to attain a wide dynamic range by combining signals obtained from the pixels of the first pixel group and signals obtained from the pixels of the second pixel group,
• wherein,
• a number of pixels in at least one of the first pixel group and the second pixel group is greater than a number of pixels in a pixel row.
