Abstract:
An image processing apparatus comprising:correction means for performing gradation correction of odd- and even-numbered pixels neighboring in a predetermined scanning direction of an image represented by an input image signal using correction information, and selection means for selecting the correction information for use by the correction means from a plurality of types of correction information having different characteristics, wherein one of the plurality of types of correction information represents a downward convex correction characteristic curve, and at a given signal level of the input image signal where the correction information that represents the downward convex curve changes stepwise, another of the plurality of types of correction information changes in correspondence with the stepwise change at the given signal level of the input image signal, and the correction information selected by said selection means for performing the gradation correction of the odd-numbered pixels is different from the correction information selected for the even-numbered pixels.
