  • Publication number: 20070201853
    Abstract: An adaptive fill-flash technique for digital photography that employs flash and no-flash image pairs. A flash image, captured using a flash of known characteristics and ambient light, and an ambient light image, which is taken with only ambient light, of the same image subject matter are acquired. A flash only image, computed by subtracting the known ambient light image from the flash and ambient light image, is computed. The flash only image and the ambient light image are then each white balanced to the flash light and the ambient light, respectively, to form two white-balanced images. These two white-balanced images are then added to form a white balanced image, I, in which the flash and ambient light color agree. It is also possible to reduce the hot spots in image I, and adjust flash strength.

  • Publication number: 20070057939
    Abstract: A system combines 2D and 3D modeling in rendering shapes and includes: a 3D modeling factory to generate a 3D model of selected shape parameters or features; a front face factory to generate 2D text and text effects, and some 2D shape effects; a ground plane factory to generate effects that are rendered on a ground plane of a shape; and a rasterizer/compositing engine to combine 2D and 3D effects generated by the front face factory, ground plan factory, and the 3D modeling factory.

  • Publication number: 20070006073
    Abstract: A graphics software program automatically generates a style transformation scheme for graphics. The graphics software program receives a selection of a style transformation and a semantic model describing a graphic. The graphics software program assigns style values for different objects of the graphic according to the style transformation and semantic model. A data structure is provided for a style transformation definition created to assign the style values to the objects of the graphic.

  • Publication number: 20060008171
    Abstract: A system and method for improving digital flash photographs. The present invention is a technique that significantly improves low-light imaging by giving the end-user all the advantages of flash photography without producing the jarring look. The invention uses an image pair—one taken with flash the other without—to remove noise from the ambient image, sharpen the ambient image using detail from the flash image, correct for color, and remove red-eye.
