Image generation system, image generation method, and information storage medium

Abstract

The invention provides an image generation system, an image generation method, an information storage medium and the like. An image of a subject captured by a camera and a virtual space image can be synthesized with high quality by a simple system. The image generation system includes: an acquisition unit that acquires a first image in which a background and a subject are imaged by a camera provided in a real space, and a second image in which the background is imaged by the camera; an image generation unit that generates a virtual space image observed from a virtual camera for imaging provided at a position of the virtual space corresponding to the position of the camera; and an image synthesis unit that extracts an image of the subject by obtaining a difference image between the first image and the second image, and generates a synthesized image in which the image of the subject is synthesized in the virtual space image.

Description

technical field [0001] The present invention relates to an image generating system, an image generating method, an information storage medium and the like. Background technique [0002] Currently, a known image generating system can generate a virtual space image observed from a virtual camera in the virtual space. In the prior art, for example, the technology disclosed in Patent Document 1 realizes virtual reality (VR) by displaying an image observed from a virtual camera on an HMD (Head Mounted Display, ie, a head-mounted display). In addition, for example, the technique disclosed in Patent Document 2 synthesizes a live image and a virtual space image through a blue screen. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 11-309269 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2011-35638 [0005] In chroma key compositing using a blue screen or a green screen, there is a problem that large-scale shooting equipment for the blue screen or ...

Problems solved by technology

[0005] In chroma key compositing using a blue screen or a green screen, there is a problem that large-scale shooting equipment for a blue screen or a green screen must be installed at the installation place of the image generation system

In addition, if the quality of the image synthesis of the virtual space image and the real space image is low, the virtual space image and the real space image cannot be harmoniously blended, thereby failing to obtain a desired result
