Patent ID: 8259138

Claim:
An image display method in which one field of an image is constructed by plural subfields weighted in brightness, and performing dynamic image coding and static image coding for controlling light emission and light non-emission of a pixel every each subfield is performed to display gradation, the dynamic image coding and the static image coding are different, the method comprising the steps of: detecting movement in the image; and identifying at least three separate pixel areas within the image, the three separate pixel areas including a transition area of pixels positioned between a dynamic image area of pixels and a static image area of pixels; dividing the transition area into a plurality of smaller transition areas, each of the smaller transition areas having a width of two or more pixels along a boundary of the dynamic image area and the static image area; determining, for each of the smaller transition areas, a respective first probability of selecting dynamic image coding and a respective second probability of selecting static image coding, wherein the respective first probability and second probability of each of the plurality of smaller transition areas are different than the respective first probability and second probability of the other smaller transition areas; and coding the pixels in each of the smaller transition areas by selecting the dynamic image coding based on the respective first probability and selecting the static image coding based on the respective second probability, the respective first and second probabilities defined for each of the smaller transition areas based on a distance from the pixels in each of the smaller transition areas to a) pixels in the dynamic image area and b) pixels in the static image area.
