ABSTRACT:
A sharpness processing method and apparatus, and a storage medium storing a program, for presenting images with increased perspective or three-dimensional effect. At least two points are designated in a direction of distance on an original image displayed on a display screen. The original image is divided by lines extending perpendicular to and touching opposite ends of a vector defined by the two points. An output image in the proper perspective is obtained by applying no processing to a near view area in the original image, applying a uniformly strong blur processing to a distant view area, and processing an intermediate area in a way to increase blur gradually in the direction indicated by the vector.
