Spinning-display blur-free image generation hardware (granted).
According to one implementation, an image generation system includes a rotor and a motor for spinning the rotor about an axis of rotation, and a display secured to the rotor. The display includes a display surface and a display aperture, a first privacy screen situated at the display surface and having a convex curvature relative to light emitted from the display surface, and a second privacy screen situated between the first privacy screen and the display aperture and having a concave curvature relative to light emitted from the display surface. The first privacy screen and the second privacy screen are configured to substantially prevent rotational blur of an image displayed by the display surface while the display is spun by the motor and the rotor.
BACKGROUND (1) Increases in computing power have made possible the generation of richly featured virtual characters capable of simulating interactivity. The illusion of interactivity may be even greater when the virtual character appears to an observer to be independent of the image generation system producing it. For example, a spinning display may be used to generate an apparently three-dimensional (3D) image that appears to float in space. However, blurring of the floating image due to rotation of the display used to produce it may be readily detectable to the eye of a human observer, and may undesirably reduce the immersiveness of the interactive experience for the observer. SUMMARY (2) There are provided systems and methods for performing rotational blur-free image generation, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the claims.
1. An image generation system comprising: a base including a rotor and a motor for spinning the rotor about an axis of rotation; a display secured to the rotor, wherein the display includes a display surface and a display aperture; a first privacy screen situated at the display surface, the first privacy screen having a convex curvature relative to light emitted from the display surface; a second privacy screen situated between the first privacy screen and the display aperture, the second privacy screen having a concave curvature relative to light emitted from the display surface; wherein the first privacy screen and the second privacy screen are configured to substantially prevent rotational blur of an image displayed by the display surface while the display is spun by the motor and the rotor. ||
7. An image generation system comprising: a base including a rotor and a motor for spinning the rotor about an axis of rotation; a display secured to the rotor, wherein the display includes a display surface and a display aperture; a first privacy screen situated at the display surface, the first privacy screen having a concave curvature relative to light emitted from the display surface; a second privacy screen situated between the first privacy screen and the display aperture, the second privacy screen having a convex curvature relative to light emitted from the display surface; wherein the first privacy screen and the second privacy screen are configured to substantially prevent rotational blur of an image displayed by the display surface while the display is spun by the motor and the rotor. ||
13. A method for use by an image generation system having a base including a rotor and a motor for spinning the rotor about an axis of rotation, a display secured to the rotor, wherein the display includes a display surface and a display aperture, a first privacy screen situated at the display surface, the first privacy screen having a first curvature relative to light emitted from the display surface, and a second privacy screen situated between the first privacy screen and the display aperture, the second privacy screen having a second curvature relative to light emitted from the display surface, the method comprising: spinning the display, using the motor and the rotor, about the axis of rotation; emitting light from the display surface to display an image while spinning the display; restricting a first viewing angle of the light emitted from the display surface at a first lateral side of the display surface using the first privacy screen having the first curvature; and restricting a second viewing angle of the light emitted from the display surface at a second lateral side of the display surface opposite the first lateral side using the second privacy screen having the second curvature to substantially prevent rotational blur of the image being displayed by the display surface while the display is spinning.
