1. A solid-state imaging device comprising:
- a pixel region in which multiple unit pixels are two-dimensionally arranged in a matrix; and
a timing generator configured to control application timings of a reset signal and a read signal to be supplied to the pixel region;
whereinduring a period for performing a long-time-period exposure once for a first pixel group constituted by multiple unit pixels arranged on one row of the pixel region, a short-time-period exposure is performed multiple times for a second pixel group constituted by multiple unit pixels arranged on the other row of the pixel region.

Abstract
According to an embodiment, a solid-state imaging device includes: a pixel region in which multiple unit pixels are two-dimensionally arranged in a matrix; and a timing generator configured to control application timings of a reset signal and a read signal to be supplied to the pixel region; and during a period for performing a long-time-period exposure once for a first pixel group constituted by multiple unit pixels of the pixel region, a short-time-period exposure is performed multiple times for a second pixel group constituted by multiple unit pixels different from the unit pixels of the first pixel group.

8. A solid-state imaging device comprising:
-
a pixel region in which multiple unit pixels are two-dimensionally arranged in a matrix; and a timing generator configured to control application timings of a reset signal and a read signal to be supplied to the pixel region, and, during a period for performing a long-time-period exposure once for a first pixel group constituted by multiple unit pixels of the pixel region, perform a short-time-period exposure multiple times for a second pixel group constituted by multiple unit pixels different from the unit pixels of the first pixel group; a frame buffer configured to hold one long-time-period exposure image obtained by the long-time-period exposure and multiple short-time-period exposure images obtained by the short-time-period exposure performed multiple times; and an image signal processing section configured to average the multiple short-time-period exposure images to generate one average short-time-period exposure image, and combine the average short-time-period exposure image with the long-time-period exposure image to generate an output image. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A solid-state imaging device comprising:
-
a pixel region in which multiple unit pixels are two-dimensionally arranged in a matrix; and a timing generator configured to control application timings of a reset signal and a read signal to be supplied to the pixel region; and an integral type A/D converter configured to convert an analog pixel signal inputted from the pixel region to a digital pixel signal;
wherein,during a period for performing a long-time-period exposure once for a first pixel group constituted by multiple unit pixels of the pixel region, a short-time-period exposure is performed multiple times for a second pixel group constituted by multiple unit pixels different from the unit pixels of the first pixel group, and the integral type A/D converter averages the pixel signals outputted by the short-time-period exposure image performed multiple times to convert the pixel signals to a pixel signal forming one average short-time-period exposure image. - View Dependent Claims (16, 17, 18, 19, 20)
