Problems solved by technology

[0003] However, when performing real-time 3D image processing, even if the von Neumann model is used, the processing load is heavy, so a more convenient expression method for specular reflection is desired.

Embodiment Construction

[0020] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] FIG. 1 is a hardware configuration diagram of an image processing device according to an embodiment of the present invention. As shown in the figure, this image processing device 10 is a game constituted by installing a DVD (Digital Versatile Disk; trademark)-ROM 25 as an information storage medium in a home game machine 46 connected to a monitor 18 and a speaker 22. device. Here, although the DVD-ROM 25 is used to provide programs and data to the home game machine 46, any other information storage medium such as a CD-ROM (Compact Disk-Read Only Memory; trademark) or a ROM (Read Only Memory) card can also be used. . In addition, the program and data may be remotely provided to the home game machine 46 via a communication network such as the Internet.

[0022] The home game machine 46 is a known computer system including a microprocessor 14 , ...

Abstract

The present invention provides an image processing device comprising a unit (62) for acquiring a light source position, a unit (64) for acquiring a visual point position and a visual line direction, a unit (66) for calculating the position of highlight provided on the surface of an object based on a visual point position, a unit (68) for calculating the intensity of highlight based on a light source position and a visual line direction, and a unit (70) for translucency-synthesizing an image representing highlight on an image representing an object based on a position calculated by the highlight position calculating unit (66) and a translucency synthesizing rate corresponding to an intensity calculated by the highlight intensity calculating unit (68).

Description

technical field [0001] The invention relates to an image processing device, an image processing method, a program and an information storage medium, in particular to a technique for expressing highlights with a relatively small processing load. Background technique [0002] A method using a von Neumann model is known as a simple method of expressing highlights (specular reflections) in three-dimensional image processing. Using the von Neumann model makes it possible to express specular reflection more easily than in the case of a method using rigorous physical laws. [0003] However, when real-time three-dimensional image processing is performed, the processing load is heavy even if the von Neumann model is used, and therefore, a more simple expression method of specular reflection is desired. [0004] The present invention is based on the above problems, and its purpose is to provide an image processing device, an image processing method, a program, and an information stor...
