ABSTRACT:
A method of reading out signals for a solid-state imaging device is disclosed. In this method, the timing of a final gate transfer clock signal .phi..sub.H1 ' and the timing of a reset pulse signal .phi..sub.R are both synchronized with two clock cycles of a horizontal CCD clock signals .phi..sub.H1 and .phi..sub.H2, to combine signal charges from two horizontally adjacent pixel pairs. Accordingly, the sensitivity under a low light intensity can be enhanced in a simple and inexpensive way without modifying the structure of the solid-state imaging device or adding an external device.
