Abstract:
A method for driving a CCD solid state imaging device comprisingan imaging section having a light receiving portion, and a vertical transfer register, a first storage section having a vertical transfer register, a second storage section having a vertical transfer register, a horizontal transfer register, and an output section, said method comprising the steps of: generating a first smear component charge in said imaging section vertical transfer register during a light receiving and storage period; transferring said first smear component charge to said first storage section vertical transfer register during a first period in a vertical blanking period; transferring a one-field amount of a signal charge of said light receiving portion, without performing a read on said light receiving portion, to said imaging section vertical transfer region during a second period; generating a second smear component charge in said vertical transfer register of said imaging section; transferring said second smear component charge from said imaging section vertical transfer region to said first storage section vertical transfer region during said second period; reading a first pixel charge and a second pixel charge from a first light receiving portion and a second light receiving portion that are vertically adjacent to one another into said imaging section vertical transfer register while applying a first and third drive pulse respectively to said imaging section vertical transfer register; mixing, in said imaging section vertical transfer register, said first pixel charge and said second pixel charge while applying a second drive pulse to said imaging section vertical transfer register during a fourth period; performing a high speed frame shift of one field amount during a fifth period; transferring said second smear component charge from said first storage section vertical transfer register to said second storage section vertical transfer register during said fifth period; adding said mixed first pixel charge and said second pixel charge to said second smear component charge during said fifth period which creates a signal plus second smear component charge; transferring said signal plus second smear component charge from said image section vertical transfer register to said first storage section vertical transfer register during said fifth period; performing a line shift during a sixth period; transferring said signal plus second smear component charge into said horizontal transfer register during said sixth period; and outputting only said second smear component charge and a picture signal containing said second smear component charge as signals from said output section.
