摘要： A liquid crystal drive apparatus includes: a storage unit storing an enhancement correction coefficient having (1/2n)×m below a decimal point where n is 3 or 4, and m is an integer which is at least 0 and less than 2n; a frame memory holding digital image information of a second frame located one frame before a first frame; a first computation unit computing a difference between digital image information of the first frame and digital image information of the second frame; a second computation unit computing enhancement image information for conducting enhancement display of an image on a liquid crystal panel on the basis of the difference and the enhancement correction coefficient; a third computation unit computing addition information by adding the digital image information of the second frame to the enhancement image information; and a drive signal generation unit generating a drive signal on the basis of the addition information to drive the liquid crystal panel.
