Multi-perspective display of an image using illumination switching

Multi-perspective display via illumination switching hardware (granted).

According to one implementation, a multi-perspective image display system includes a motor configured to spin a rotor, a display screen coupled to the rotor, and a controller. The controller is configured to cause the motor to spin the display screen, using the rotor, about an axis of rotation at a spin rate, and to determine, based on the spin rate, an illumination on-time for an illumination source of the display screen. The controller is also configured to sequentially render each of multiple different perspectives of an image on the display screen during each revolution of the display screen about the axis of rotation and, concurrently with sequentially rendering each of the plurality of perspectives of the image on the display screen, to strobe the illumination source of the display screen based on the determined illumination on-time to display the multiple different perspectives of the image.

BACKGROUND (1) Increases in computing power have made possible the generation of richly featured virtual imagery capable of simulating in-person interactivity. However, the display screens with which many modern communication devices are equipped are typically designed to display a two-dimensional (2D) image from a single viewing perspective. As a result, and despite their ability to display sharp, richly featured, high definition images, interactive group activities centered on those devices, such as multi-player gaming, for example, tend to be less than optimally engaging and immersive if not limited entirely. (2) An alternative to the conventional approach to providing 2D images is to render interactive group activities using 3D imagery. However, several significant obstacles to wider use of 3D imagery in gaming and entertainment exist. For example, in order to project a 3D image, solutions often entail multiple expensive projectors, multiple sets of augmented reality (AR) headgear, and/or other complex display technology is typically required to create the illusion of a real-world 3D image. Further system complications can occur if the 3D image is to be viewed from multiple perspectives and still maintain a desirable level of realism (e.g., positioning and location of users and images, time synchronization, display performance, user comfort, environmental restrictions, etc.). SUMMARY (3) There are provided systems and methods for displaying multiple perspectives of an ima
