Video game machine, gaming image display control method and display mode switching control method

Abstract

A video game machine includes a monitor which permits three-dimensional viewing, a virtual camera controller which selectively provides on-screen presentation in 2D display mode in which two virtual cameras for capturing images are matched with each other and in 3D display mode in which the two virtual cameras are set to achieve a prescribed distance therebetween, an image display controller which generates a 3D image presented on the monitor from image data acquired by the two virtual cameras, a display mode switching processor which repositions the two virtual cameras from the positional relationship in one display mode to the positional relationship in the other in a stepwise fashion. Switching between the 2D and 3D display modes is smoothened and stimulation of a player's eyes or brain caused by a sudden change between states with or without stereoscopic effect is suppressed.

Description

technical field [0001] The present invention relates to a video game device for selectively switching game images to two-dimensional display and three-dimensional display (stereoscopic display) and displaying them on a screen, a game image display control method, and a display mode switching control method. Background technique [0002] Various technical solutions for displaying 3D images on a display screen have been proposed in the past. The display method of 3D images is generally a parallax barrier method, and there are known glasses-based methods using polarizing materials, liquid crystal shutters, and glasses, and parallax-panorama methods and lenticular lens methods that are non-glasses-based methods. In addition, in recent years, proposals have been proposed that can switch display techniques between 2D images and 3D images. That is, Patent Document 1 (Japanese Patent Publication No. 3973525) describes a mobile phone having a monitor realizing a liquid crystal panel...

Problems solved by technology

[0003] In the device described in Patent Document 1, it is necessary to create in advance the content of 3D video data received from a web site or mail through a special mobile phone, that is, video data for 3D stereoscopic display.

In addition, Patent Document 1 also describes a built-in processing unit that converts one 2D image that has already been created into image data for 3D stereoscopic display. However, even if one 2D image is converted into image data for 3D stereoscopic display, only Simulate 3D images

In addition, Patent Document 1 only describes obtaining 3D video data from the outside, or forming a simulated 3D image from a single 2D image, and there is no description about the relationship between the two cameras.

In particular, there is no mention of the subject of switching between 2D display and 3D stereoscopic display
