A CCD output signal generating circuit includes a CCD type charge transfer device for transferring and outputting signal charges in response to the drive signal of a frequency fc, an output circuit for generating an output signal corresponding to the output signal charges from the CCD type charge transfer device, and a correlated double sampling circuit. The CDD output signal generating circuit also has a low-pass filter circuit which, having a cut-off frequency set within a range of 2.5fc to 4fc, and being connected between the output circuit and the correlated double sampling circuit, acts to filter an output signal from the output circuit before supplying the signal to the correlated double sampling circuit.
