ABSTRACT:
To provide a solid-state image sensor, wherein no field adjustment of timing pulse phases used in the signal processor or of signal balances is needed, and noise performance is more improved, with a simple, miniaturized and economical configuration, a solid-state image sensor (1) of the invention comprises: a CCD (2) configured on a semiconductor chip for generating a CCD signal according to an optical image focused on a sensor area thereof; an on-chip signal processor (4) configured on the semiconductor chip by way of the same fabrication process with the CCD including a noise reduction circuit for eliminating noises from the CCD signal, an AGC circuit for amplifying output of of the noise reduction circuit; and a timing pulse generator (3) configured on the semiconductor chip by way of the same fabrication process with the CCD (2) for generating timing pulses used the on-chip signal processor. The on-chip signal processor (4) of the solid-state image sensor (1) may further comprise an A/D converter for converting output of the AGC circuit into a digital signal.
