There is provided an image processing apparatus, an image display and an image processing method which are capable of preventing an unnatural change in image quality to image processing. A luminance distribution detecting circuit detects a luminance distribution as the histogram distribution of YUV signals. A gain calculating circuit and a gain limiter detect a gain variation on the basis of luminance distribution data. The gain limiter limits the gain variation to a gain variation threshold or less. The gain limiter and a delay circuit carry over the gain variation of a portion exceeding the gain variation threshold to the next image frame so as to modify the gain variation. A gamma correction circuit performs image processing (contrast control) on the YUV signals on the basis of the gain variation modified.
