Patent ID: 8482645

Claim:
A solid-state imaging device employing a plurality of unit pixels each having an opto-electric conversion section configured to convert incident light into electric charge and an electric-charge holding section configured to hold a signal voltage representing said electric charge produced by said opto-electric conversion section, said solid-state imaging device further comprising: read means for reading out a reset voltage appearing on said electric-charge holding section as a result of setting said electric-charge holding section at a predetermined voltage from said electric-charge holding section as a reset level at a reset-level read time after reading out said signal voltage representing said electric charge produced by said opto-electric conversion section from said electric-charge holding section as a signal level at a signal-level read time and for computing a difference between said signal level and said reset level in order to generate a pixel signal; and control means for controlling an operation to provide said unit pixel with a pixel driving signal driving said unit pixel but affecting a coupling phenomenon occurring in said electric-charge holding section so as to make the state of said pixel driving signal at a first reset time at which said electric-charge holding section is reset immediately prior to a transfer of electric charge from said opto-electric conversion section to said electric-charge holding section the same as the state of said pixel driving signal at a second reset time at which said electric-charge holding section is reset immediately prior to an operation to read out said reset level from said electric-charge holding section, and the state of said pixel driving signal at said signal-level read time the same as the state of said pixel driving signal at said reset-level read time.
