Abstract
A display panel driver includes first and second scaler circuits and a pixel data feeding section which feeds to the first scaler circuit first divisional image pixel data corresponding to a first divisional image and feeds to the second scaler circuit second divisional image pixel data corresponding to a second divisional image. The pixel data feeding section also feeds to the first scaler circuit first boundary pixel data corresponding to pixels in a portion of the second divisional image, adjacent to the first divisional image and feeds to the second scaler circuit second boundary pixel data corresponding to pixels in a portion of the first divisional image, adjacent to the second divisional image. The first scaler circuit performs image scaling on the basis of the first divisional image pixel data and the first boundary pixel data and the second scaler circuit performs image scaling on the basis of the second divisional pixel image data and the second boundary pixel data.
