Abstract
An imaginary plane and a projection plane are set on both sides of three-dimensional image data to be parallel to each other. A plurality of projection rays are projected from the imaginary plane onto the projection plane. Sampling points for pixel values are set on each projection ray. Pixel values at the sampling points are interpolated by using the three-dimensional image data. The maximum value, integral value, standard deviation, and the like of such interpolated pixel values on the projection rays are projected on the projection plane when the sampling points are set, constant sampling periods are set, but the sampling start points are determined by using random numbers for the respective projection rays. With this operation, the phases of the sampling points on all the projection rays are set to be different from each other, thereby preventing moire, on a projected image, which occurs when interpolated pixel values periodically vary.
