  • Patent number: 11533459
    Abstract: A projector and a brightness adjusting method are provided. The projector includes a distance sensor configured to detect a distance between the projector and a projection plane, a light source configured to provide an illumination beam, a brightness controlling circuit configured to control the light source, and a processor coupled to the distance sensor, the light source, and the brightness controlling circuit. The processor calculates according to the distance to obtain an image size of a projected image on the projection plane. The processor obtains a current value corresponding to the image size according to a color table. The processor instructs the light source to adjust a luminous flux of the illumination beam according to the current value for generating a target brightness value of the projected image. When a brightness of the projected image is excessively large, a brightness of an image beam of the projector is automatically reduced.

  • Patent number: 11523094
    Abstract: A display system for displaying a panoramic image and an operation method thereof are provided. The display system for displaying a panoramic image includes N projectors and a controller. The N projectors project N sub-images according to N image data and form a panoramic image. Each sub-image has a sub-image overlapping area, so that two adjacent sub-images of the N sub-images partially overlap, and that a first sub-image and an Nth sub-image of the N sub-images partially overlap. The controller copies a first edge image corresponding to a first edge of an original image and connects the first edge image to a second edge of the original image that is opposite to the first edge, so as to generate an extended image corresponding to the sub-image overlapping area. The controller slices an adjusted image containing the original image and the extended image to generate the N image data.

  • Patent number: 11475549
    Abstract: High dynamic range (HDR) support is provided for legacy application programs, such as games that are configured to display standard dynamic range (SDR) frames. HDR frames may be generated without modifying the legacy application program. The buffer creation process of the legacy application program is intercepted and modified before creation of the SDR format buffer so that the buffer is configured to use an upgraded SDR format having an increased bit depth compared with a conventional SDR buffer. Rather than tone mapping and quantizing rendered image data to the lower bit depth for storage in the conventional SDR buffer, the rendered image data is tone mapped and quantized for storage at the increased bit depth of the upgraded SDR buffer. Therefore, the luminance and greater dynamic range of the tone mapped data is better preserved compared with outputting conventional SDR frames.
