Abstract
The image signal generating apparatus for a liquid crystal display element. A corner detector detects, when an input image signal contains multiple frame images each of which includes a first image area having a first tone and including a corner portion and a second image area having a second tone higher than the first tone and being adjacent in vertical, horizontal and oblique directions to the corner portion, the corner portion in each frame image, a tone provider generates an output image signal by providing a third tone lower than the second tone to one specific pixel adjacent in the oblique direction to a vertex of the corner portion in at least one of the multiple frame images. The tone provider provides the third tone to the specific pixel when the input image signal is a moving image signal.
