Patent ID: 8159433

Claim:
A liquid crystal drive apparatus comprising: a storage unit configured to store an enhancement correction coefficient having a value equal β+(1/2 n )×m, where n is 3 or 4, and m is an integer which is at least 0 and less than 2 n , and β is a maximum integer value which does not exceed the value of the enhancement correction coefficient; a frame memory configured to hold digital image information of a second frame located one frame before a first frame; a first computation unit configured to compute a difference between digital image information of the first frame and digital image information of the second frame; a second computation unit configured to compute enhancement image information for conducting enhancement display of an image on a liquid crystal panel on the basis of the difference between digital image information of the first frame and digital image information of the second frame, digital image information of the second frame and the enhancement correction coefficient; a third computation unit configured compute addition information by adding the digital image information of the second frame to the enhancement image information; and a drive signal generation unit configured to generate a drive signal on the basis of the addition information to drive the liquid crystal panel.
