  • Projection display device, projection display method, and computer program
    Patent number: 9257094
    Abstract: A projection display device according to the invention includes a separating unit that assigns X separation information for identifying a type of an image to each pixel by using a characteristic amount of the input image, a luminance detecting unit that detects a luminance of a screen, a first determining unit that determines a first target region indicating a region on which halftone processing of converting the number of gradations is performed on the input image by using the X separation information, and a halftone processing unit that executes the halftone processing that varies depending on the luminance on the first target region.

  • Image projecting apparatus, image processing method, and computer-readable storage medium
    Patent number: 9183605
    Abstract: An image projecting apparatus includes an image projecting unit configured to project received original image data on an image projection surface; an area identifying unit configured to identify an obstruction area in which different content is displayed as compared to a normal projection surface to be projected based on the original image data; and a layout modifying unit configured to modify a layout of an object included in the original image data that is projected, on the basis of the object and the obstruction area on the image projection surface.
