A projector assembly having a projecting device and a display screen with a film. The display screen is changeable from between opaque and transparent and the projecting device selectively rear projects an image onto the film such that the image is visible to a user generally from the front side of the screen. When the projector is off or the projection of images is otherwise stopped under predetermined conditions, the screen becomes transparent to provide the user a clear view through the display screen. When the projector is off power is simultaneously applied to the film which becomes transparent. A control device coordinates the application of power with the image projection, such that when the projected image is removed the screen becomes clear to see through the display screen, and when the projected image returns the screen becomes opaque for viewing the image.

Disclosed herein are a method and apparatus for normalizing the size of content in a multi-projection theater and a computer-readable recording medium. The method may include receiving theater parameters stored in a database, computing the scale factor of an image project on a main screen based on the received theater parameters, controlling the image projected on the main screen by incorporating the computed scale factor into the image, and controlling an image projected on a sub-screen so that the height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.

The present invention provides a structure of short-throw ambient light rejecting screen, which comprises a base and an optical structure device disposed on the base. The optical structure device includes a plurality of optical structure parts. Each of the plurality of optical structure parts includes a first side, a second side, and a base part. The first side and the base form a first angle for reflecting a light source. The second side and the base form a second angle for absorbing a light source. The base part is a length on the base confined by first side and the second side. The first angle is 20˜40 degrees. The second angle is 70˜90 degrees. The length on the base part is 250˜350 um. By adjusting the first angle, the second angle, and the length on the base part of each optical structure part, the height of the optical structure part can be maintained constant. In addition, the differences between the incident projection angles can be reduced as well. By improving the process yield, the appearance of the scrolled screen can form a neat cylinder.

Provided herein are systems and methods to configure an immersive theater environment by moving one or more screens. A movie screen can be provided with one or more actuators coupled to the movie screen, wherein the one or more actuators are configured to move the movie screen in a plurality of directions including, for example, up, down, left, right, back, forward, pitch, roll, and yaw. This system can include a processor coupled to the actuator, wherein the processor is configured to control the movement of the one or more actuators, synchronize cinema content for movement of the movie screen, process cinema content for metadata cues indicating movement of the movie screen, and track positions of the movie screen.

The present image generator visually suppresses a gap between two adjacent reflective surfaces of a reflective display. The image generator comprises memory and a processor. The memory stores position of the gap on the reflective display. The processor analyses a stream of images to be displayed on the reflective display and determines corresponding lighting data alongside the gap. The processor further controls at least one lighting unit located behind a seam inserted in the gap based on the determined lighting data.

The present disclosure relates to the technical field of digital projection display, and discloses a projection method and a projection apparatus. The method includes: acquiring a target object image; identifying attribute information of a target object based on the target object image; acquiring preset projection content based on the attribute information of the target object; acquiring a projection path; and projecting a projection screen based on the preset projection content and controlling the projection screen to move along the projection path. In this way, the projection is more flexible and more pertinent.
