Patent ID: 7474280

Claim:
An image display apparatus, in which a current TV field period is divided into a plurality of sub-fields that are respectively given luminance weights and are arranged in order of time, and a gray-scale image for the current TV field period is displayed by coding input pixel image signals using different coding modes that are switched in accordance with an amount of movement from an image of a past TV field period to the image of the current TV field period, comprising: a first circuit unit in which a combination of sub-fields is selected for each pixel using a signal calculated from the amount of movement, and a light emission state being sustained in each pixel during the selected sub-fields; and a second circuit unit for providing an arbitrarily spaced-modulated signal used for switching between the different coding modes so that the different coding modes are interspersedly applied to input pixel image signals that correspond to an image area where the switching between the different coding modes is needed and that show a predetermined characteristic.
