Abstract

Motion blur periods (bf) are detected () from gradation differences (g) between a first image signal (d) and a second image signal (d), gradation differences (g) between the second image signal (d) and a third image signal (d), and results of the detection of transition periods (h) in the gradations of the second image signal (d), and the second image signal (d) is corrected () only during the detected motion blur periods (bf). Transition periods (h) are deemed to occur when, for example, the absolute value of a gradation change in the second image signal is greater than a first predetermined threshold value (S) and less than a second predetermined threshold value S(<S). Motion blur in the image signal can be detected without increased circuit size, and accordingly, the detected motion blur can be reduced.
