  • Patent number: 11950028
    Abstract: A projector has a projection optical system including a projection lens and a processing device. The processing device makes the projection optical system project a correction image having a rectangular shape. The number of correction points arranged on a first side out of two sides connecting to a vertex located the farthest from the projection lens when projected on a projection surface out of four vertexes of the correction image is larger than the number of correction points arranged on a side different from the two sides. The processing device receives an operation of moving first correction point included in the correction points arranged on the first side, and makes the projection optical system project an output image obtained by applying a distortion correction based on the operation to an input image.

  • Patent number: 11418840
    Abstract: Techniques are disclosed for recognizing aspect ratio errors in image frames of a video and reporting the same. An aspect ratio checker application receives a video that includes multiple image frames and identifies aspect ratio changes in those image frames using a first differential of a time series that includes determined positions of the top, bottom, left, and right of content regions within the image frames. In particular, the aspect ratio checker may identify aspect ratio changes based on non-zero points of the first differential, and the aspect ratio checker further determines aspect ratios of content regions within image frames corresponding to the non-zero points of the first differential. In addition, the aspect ratio checker may generate and display a report indicating the determined aspect ratios and image frame ranges associated with those aspect ratios.

  • Patent number: 11393366
    Abstract: An example calibration device includes a projector projecting a first light region including a first area onto and extending over a border of a non-patterned touch mat. A camera captures a first image of the first light region. A processor establishes a first set of four corner coordinates of the touch mat. The projector projects a second light region including a second area onto the touch mat. The second area is smaller than the first area. The camera captures a second image of the second light region. The processor performs a perspective transformation of the second image using the first set of corner coordinates and a resolution of the second light region to get a second set of four corner coordinates of the touch mat in a coordinate plane of the projector. The processor aligns the first and second set of four corner coordinates.
