Color smear correcting apparatus
First Claim
1. A color smear correcting apparatus comprising:
- means for outputting a discriminating signal representing whether one of the states of a parent picture and a son picture of a video signal output from a single frame sequential imaging apparatus corresponds to either a moving picture or a still picture; and
means for independently setting a color smear correction on said parent picture and the color smear correction on said son picture, when one of said states is judged to be a moving picture on the basis of said discriminating signal.

Abstract
In the color smear correcting apparatus of the present invention, the states of a parent picture and son picture of a video signal from a frame sequential imaging apparatus are discriminated and the color smear correction on the parent picture and the color smear correction on the son picture are independently set. Or, in the color smear correcting apparatus of the present invention, whether a moving picture or a still picture is discriminated on a parent picture and son picture of a video signal output from an endoscope apparatus including a frame sequential imaging apparatus and the color smear correction on the parent picture and the color smear correction on the son picture are independently set.

4. A color smear correcting apparatus comprising:
-
means for outputting a discriminating signal representing different levels in which one of a parent picture and a son picture of a video signal output from an endoscope apparatus including a single frame sequential imaging apparatus corresponds to either a moving picture or a still picture; and means for independently setting a color smear correction on said parent picture and the color smear correction on said son picture on the basis of said discriminating signal.
