Abstract
A display gradation number acquisition unit acquires the number of display gradations of the video data during each horizontal scanning period based on a gradation histogram. A first display gradation holding period value generator generates a first display gradation holding period value based on a gradation value difference. A second display gradation holding period value generator generates a second display gradation holding period value based on the number of pixels for each display gradation. A holding period provisional value generator selects a display gradation holding period value having a larger value to generate a holding period provisional value. A holding period total value generator generates a holding period total value that is a sum of the holding period provisional value during each horizontal scanning period. A holding period optimum value generator generates a holding period optimum value of each display gradation.
