Abstract
Abstract A method for driving a solid state image pickup device is provided in which charges stored in a group of photoelectric conversion elements of odd rows are first discharged or read out, and then charges stored in a group of photoelectric conversion elements of even rows are read out or discharged, thereafter, the charges stored in the group of photoelectric conversion elements of even rows are first discharged or read out and then charges stored in the group of photoelectric conversion elements of odd rows and read out or discharged.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A method for driving a solid state image pick-up device having photoelectric conversion elements arranged in a row direction, comprising the steps of: reading out, for discharging, signal charges stored in a first group of alternate rows of photoelectric conversion elements during a first field interval; reading out, for detection, signal charges stored in a second group of the remaining alternate rows of photoelectric conversion elements during said first field interval; reading out, for discharging, signal charges stored in said second group of photoelectric conversion elements during a subsequent second field interval; and reading out, for detection, signal charges stored in said first group of photoelectric conversion elements during said second field interval.
Claim 2
Independent Claim
113 words
A method for driving a solid state image pick-up device having photoelectric conversion elements arranged in a row direction, comprising the steps of: reading out, for discharging, signal charges stored in a first group of alternate rows of photoelectric conversion elements during a first field interval; reading out, for detection, signal charges stored in a second group of the remaining alternate rows of photoelectric conversion elements during said first field interval; reading out, for discharging, signal charges stored in said second group of photoelectric conversion elements during a subsequent second field interval; and reading out, for detection, signal charges stored in said first group of photoelectric conversion elements during said second field interval.
Claim 3
Dependent Claim
22 words
A method according to claim 1, wherein said solid state image pickup device includes charge coupled devices of an interline transfer system.
Claim 4
Independent Claim
111 words
A method for driving a solid state image pick-up device having photoelectric conversion elements arranged in a row direction, comprising the steps of: reading out, for detection, signal charges stored in a first group of alternate rows of photoelectric conversion elements during a first field interval; reading out, for discharging, signal charges stored in a second group of the remaining alternate rows of photoelectric conversion elements during said first interval; reading out, for detection, signal charges stored in said second group of photoelectric conversion elements during a subsequent second field interval; and reading out, for discharging, signal charges stored in first group of photoelectric conversion elements during said second field interval.
Claim 5
Independent Claim
