  • Patent number: 11159764
    Abstract: A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.

  • Patent number: 11153526
    Abstract: Techniques for detecting epileptic triggers in video content by storing a first sequence of frames of a video stream in a first buffer. The technique can further comprise generating a second sequence of subframes and storing the second sequence of subframes in a second buffer. The technique can further comprise generating average intensity values for the second sequence of subframes in the second buffer and calculating intensity changes between consecutive subframes in the second sequence of subframes based on the average intensity values. The technique can further comprise determining that a number of intensity changes between consecutive subframes in the second sequence of subframes exceeds an oscillation threshold and tagging the frames in the first buffer corresponding to the subframes in the second buffer as hazardous.

    Abstract: A projection display apparatus includes a motion deblurring circuit, an image processing circuit, a color managing circuit, an image projection display device and a multi-axis shifting device. The motion deblurring circuit receives an input video signal with the first resolution and processes it to reduce a motion blur. The image processing circuit receives the input video signal processed by the motion deblurring circuit, and converts it into a plurality of the output video signals with the second resolution. The color managing circuit receives the output video signals with the second resolution, separates the color of the output video signals, and outputs it. The projection device including a digital micro display component has a native resolution with a second resolution, and displays the output video signals. The multi-axis shifting device shifts the output video signals outputted from the image projection display device onto a projection screen with a control timing signal.

  • Patent number: 11057675
    Abstract: A media streaming device is provided that includes a media streaming module, a super capacitor and a protection module. The media streaming module provides the media stream. The super capacitor has a first terminal coupled to a power-supplying path and a second terminal coupled to a ground terminal. The protection module includes a current limiter and a disabling unit. The current limiter receives a power signal and performs current-limiting to generate a fixed-current power to charge the super capacitor and supply power to the media streaming module through the power-supplying path. The current limiter further detects a voltage of the first terminal of the super capacitor. The disabling unit disables the media streaming module when the voltage of the first terminal of the super capacitor is not higher than a voltage threshold value, and enables the media streaming module when the voltage is higher than the voltage threshold value.

  • Patent number: 10924717
    Abstract: A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, “virtual reality” picture-dominance effect not previously obtainable in such theaters. The invention uses a zero-gain or nominal-gain curved screen to accommodate a wide-screen presentation, and a digital projector capable of delivering fourteen foot-lamberts or more of light to the screen. It can support any theatrical aspect ratio for presentation, including 2.76:1. To eliminate image distortion, the invention uses mapping software to correct the image for the geometry of the auditorium and the shape of the screen. This correction is established for every aspect ratio displayed in the auditorium in which the invention is installed, and aspect ratios can be changed to display content with different aspect ratios during a program. The images delivered to viewers through the invention deliver the full benefit of the native aspect ratio in which they are displayed.
