Title:
SOLID-STATE IMAGE PICKUP DEVICE
Document Type and Number:
Japanese Patent JPH089267
Kind Code:
A
Abstract:

PURPOSE: To increase the dynamic range and also to increase the amount of charge transferred on a charge transfer path by transferring the charge generated by the photoelectric transducers arranged in two rows at both sides of each vertical charge transfer path to a horizontal charge transfer path.

CONSTITUTION: Two pairs are formed between two columns of photoelectric transducers arranged in a (4×6) two-dimensional array and a vertical CCD 3 formed between those two columns. Each photoelectric transducer is provided with a transfer gate 2 against the CCD 3 of each relevant pair. Then the transfer of the charge signal produced from each photoelectric transducer is controlled to the CCD 3 by the open/close control of the gate 2. Meanwhile a horizontal CCD 4 contains three CCD packets arranged between two CCD 3 adjacent to each other. Thus the charge generated by the photoelectric transducers which are arranged in two rows on both sides of each vertical charge transfer path is transferred to a horizontal charge transfer path through a vertical charge transfer path formed between two columns of photoelectric transducers.
