AI Technical Summary

Technical Problem

Existing image generation methods lack a sense of presence due to weak relevance between avatar images and specific images, resulting in unrealistic compositions.

Method used

A method that involves detecting performer movements, generating a 3D model of an avatar, placing it in 3D space, and irradiating it with virtual illumination light based on a specific image to reflect its colors, thereby enhancing the relevance and realism of the avatar image.

Benefits of technology

Generates more realistic and immersive images by aligning the avatar's colors with the specific image, creating a stronger sense of presence.

Abstract

The objective is to provide an image generation method and image generation program that can generate realistic avatar images. [Solution] In a configuration in which an external input image captured from external video data by a capture device 112 is used as the background image, and an avatar image based on an avatar 3D model created by an avatar 3D model generation program is placed in front of the external input image to create and output a composite image, the avatar image placed in front of the external input image is an avatar image generated from an avatar 3D model that is illuminated with virtual light based on the external input image, and the color of the avatar image is changed based on the external input image.
