Abstract
A distorted image generating section directly renders an image having a distortion such that a proper image can be seen when viewed through an eyepiece lens. Specifically, the distorted image generating section calculates which position a target pixel on a view screen will be displaced to by the lens, generates a ray of light that passes from a viewpoint through a pixel at a displacement destination, and uses color information obtained by ray tracing as a pixel value of the target pixel.
Claims11
An image generating device for generating an image to be observed through an eyepiece lens for enlarging a user's viewing angle, comprising:
- a distorted image generating section for rendering a display image having a distortion at a predetermined rate by acquiring a displacement destination of a target pixel on an image plane due to an image distortion caused, as the user changes a viewpoint of the user in a virtual space to a new viewpoint of the user in the virtual space, by the viewing angle enlargement features of the eyepiece lens, specifying color information in a space of a display target that corresponds to the displacement destination on a basis of the displacement destination and relative positions of the viewpoints, and using the specified color information as a pixel value of the target pixel;
- and
- an output section for successively outputting data of the display image.
A head-mounted display comprising:
- an image generating device for generating an image to be observed through an eyepiece lens for enlarging a user's viewing angle, including
- a distorted image generating section for rendering a display image having a distortion at a predetermined rate by acquiring a displacement destination of a target pixel on an image plane due to an image distortion caused, as the user changes a viewpoint of the user in a virtual space to a new viewpoint of the user in the virtual space, by the viewing angle enlargement features of the eyepiece lens, specifying color information in a space of a display target that corresponds to the displacement destination on a basis of the displacement destination and relative positions of the viewpoints, and using the specified color information as a pixel value of the target pixel, and
- an output section for successively outputting data of the display image;
- and
- a display panel for displaying the display image.
An image generating method by an image generating device for generating an image to be observed through an eyepiece lens for enlarging a user's viewing angle, the image generating method comprising:
- acquiring a displacement destination of a target pixel on an image plane due to an image distortion caused, as the user changes a viewpoint of the user in a virtual space to a new viewpoint of the user in the virtual space, by the viewing angle enlargement features of the eyepiece lens;
- rendering a display image having a distortion at a predetermined rate by specifying color information in a space of a display target that corresponds to the displacement destination on a basis of the displacement destination and relative positions of the viewpoints, and using the specified color information as a pixel value of the target pixel;
- and
- successively outputting data of the display image to a display device.
A non-transitory, computer-readable storage medium containing a computer program, which when executed by a computer, causes the computer to generate an image to be observed through an eyepiece lens for enlarging a user's viewing angle by carrying out actions, comprising:
- acquiring a displacement destination of a target pixel on an image plane due to an image distortion caused, as the user changes a viewpoint of the user in a virtual space to a new viewpoint of the user in the virtual space, by the viewing angle enlargement features of the eyepiece lens;
- rendering a display image having a distortion at a predetermined rate by specifying color information in a space of a display target that corresponds to the displacement destination on a basis of the displacement destination and relative positions of the viewpoints, and using the specified color information as a pixel value of the target pixel;
- and
- successively outputting data of the display image.
