ABSTRACT:
A CCD output signal processing method includes the steps of sampling a CCD output signal supplied from a CCD in synchronism with a transfer clock to thereby generate sampled CCD output data within an n-th section corresponding to one pixel (n is an arbitrary integer), expanding the sampled CCD output data to a Fourier series which has a basic waveform having aa period substantially corresponding to a reciprocal of a frequency of the transfer clock, and calculating an amplitude of the basic waveform from first-order Fourier coefficients included in the Fourier series, the amplitude of the basic waveform being a corrected amplitude of the CCD output signal supplied from the CCD. There is provided a CCD output signal processing apparatus which implements the above-mentioned method.
