Title:
SOLID-STATE IMAGE PICKUP DEVICE DRIVE METHOD AND SIGNAL PROCESING METHOD
Document Type and Number:
Japanese Patent JP2988557
Kind Code:
B2
Abstract:
PURPOSE: To reproduce a picture even under a strong light incidence condition by which a signal reaches a saturation level so as to extend the dynamic range.
CONSTITUTION: Pulse application electrodes G1-G4 are connected to a transfer gate 4 forming each bit and the electrodes G1, G3 among them are connected to a read gate 2. A high level pulse is applied to the electrodes G1, G3 for a prescribed time interval and the signal charge stored in a photo diode 1 is read by a vertical transfer section 3 for a time resulting from subtracting the pulse interval time from a field period. Succeedingly, the signal charge stored in the photo diode 1 is read by the vertical transfer section 3 for the pulse application interval and the signal charge is added to the signal charge read precedingly. Thus, the signal charges to be summed in the vertical transfer section 3 are transferred one by one line sequentially to a horizontal transfer section 5 for the transfer period and the charge is outputted from an output section 6.
