Abstract
Provided is a display device for executing processing of enlarging a predetermined region (200) of an image rightward by as much as 0.25 pixels with a first pixel (251) as a reference, and processing of reducing the predetermined region (200) rightward 0.25 pixels with a seventh pixel (257) as a reference, to thereby control the predetermined region (200) to be shifted rightward. The image is thus shifted while changing a magnitude of the predetermined region (200) so that an enlarged amount and a reduced amount per one step are smaller than 1 pixel, thereby making it possible to shift the image while changing the magnitude of the image without giving a visually unnatural impression. The display device can be applied to processing using digital signals because a lighting state of each pixel is controlled. The shift of the image can be easily performed without executing pixel conversion processing or the like. The shift is performed while changing the magnitude of the image, which suppresses blurring of the entire image as compared with a structure for shifting the image without changing the magnitude of the image.
