| (54) | Display state controller, display device, display state control method, program therefor, and recording medium recorded with the program |
| (57) 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.
