  • Patent number: 11119320
    Abstract: Systems and methods are provided for controlling and/or modifying operation of a red, green, blue (RGB) laser assembly for creating images in mixed-reality environments. Initially, the lasers in the RGB laser assembly operate in a low power or non-emitting state. Then, the lasers emit laser light to illuminate a pixel or a group of pixels. This illumination occurs for a period of time spanning less than 15 nanoseconds. By causing the lasers to emit laser light only during this short period of time, the resulting laser light is structured with a reduced spatial coherence level. Once the time period elapses, then the lasers again return to the non-emitting state. This process repeats for each pixel such that the lasers generate pulsed emissions. By operating the lasers with a reduced spatial coherence, undesired visual artifacts can be reduced or eliminated within the target display area.

The detection unit detects an object other than the projection image, which included in the captured image data, based on the captured image data and the projection image data. The projection unit switches projection image for each line or for each block, by scanning. The image capturing unit starts sequential image capturing from a region of the projection surface, in which switching is completed, during a period when at least switching of the projection image is performed.

  • Patent number: 10554939
    Abstract: A projection system includes an invisible light projector, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The invisible light projector emits pulsed invisible light to project the measurement pattern. The image generator generates the image data based on an image captured in accordance with a timing for the pulsed light emission.

    Abstract: A method for replacing image data in a destination region that is divided into sub-pieces along one or more cutting paths, which start and end at two different points on the border, and finding replacement data for the sub-pieces. The cutting paths may be determined as a function of the type of image structured at the start and the end points. The cutting paths may also be determined as a function of the area of the sub-pieces and the lengths of the cutting paths. Optionally, the destination region may be determined by a spot detection algorithm. Further optionally, the spot detection algorithm may comprise calculation of a high pass filter, or detection of areas of luminosity and border-to-volume ratios.
