Abstract:
A color separator circuit for performing color separation on image signals fed thereto from a solid-state image-sensing device having pixels provided with a plurality of types of color filters, comprising:a contour detector for detecting a contour of a subject sensed by the solid-state image-sensing device by recognizing variations in signals levels of the image signals fed from the solid-state image-sensing device; a first color separation filter for correcting the image signals fed from the solid-state image-sensing device by correcting each image signal based on a plurality of preceding and succeeding image signals; a second color separation filter for correcting the image signals fed from the solid-state image-sensing device by correcting each image signal based on a plurality of preceding and succeeding image signals; and a selector for selecting the second color separation filter when correcting image signals that represent a portion of an image that corresponds to the contour detected by the contour detector and selecting the first color separation filter when correcting image signals that represent a portion of the image other than the portion corresponding to the contour, wherein the first color separation filter uses a smaller number of image signals to correct an image signal than the second color separation filter.
