摘要： An image-processing apparatus includes an integration section to integrate an image signal in more than one unit of horizontal synchronization period; an interpolation section to carry out an interpolation on the basis of integration values output by the integration section in order to generate integration values corresponding to a predetermined number of sampling positions set in advance during at least one period of flickers appearing on a screen under a fluorescent lamp; a normalization section to normalize an integration value output by the interpolation section or to normalize a difference value between integration values output by the interpolation section as integration values for adjacent fields or frames, respectively; a frequency analysis section to extract a spectrum of normalized integration value or difference values output by the normalization section; and a flicker inference section to infer a flicker component from the spectrum extracted by the frequency analysis section.
