  • Publication number: 20060129950
    Abstract: A method of a user interface for red eye removal in a portable device includes displaying a first screen having an image and a first menu. If a user selects a first icon in the first menu, the method further includes displaying a second screen having the image after automatic red eye removal and a second menu. If the user selects a second icon in the second menu, the method further includes redisplaying the second screen having the image prior to automatic red eye removal. If the user selects a third icon in the second menu, the method further includes displaying a third screen having the image, a visual indicator for the location of manual red eye removal, and a third menu. If the user selects a fourth icon in the third menu, the method further includes redisplaying the second screen with the image after manual red eye removal.

  • Publication number: 20050063597
    Abstract: A method for indexing minimum coded units (MCUs) in a Joint Photographic Expert Group (JPEG) bit stream includes (1) entropy decoding a first MCU to determine a bit offset of a second MCU and a DC coefficient of the first MCU, wherein the first MCU immediately precedes the second MCU in the bit stream, and (2) indexing the second MCU by storing the bit offset and the DC coefficient in an index. The method may further include (3) receiving a request for the second MCU, (4) reading the index to determine the bit offset of the second MCU and the DC coefficient of the first MCU, and (5) entropy decoding the second MCU starting at its bit offset in the bit stream, wherein the entropy decoding the second MCU includes determining a DC coefficient of the second MCU using the DC coefficient of the first MCU.

  • Publication number: 20030063797
    Abstract: Smart selection and paste operations for image processing use a wide edge area for selection and masking of an object from a source image. The wide edge area, which can be designated with a brush tool, allows a user to select all of a desired object without requiring pixel-by-pixel identification of the objects edge. A masking unit operates on the edge area and designates each portion or pixel of the edge area as being foreground, background, or a combination of foreground and background. The mask unit constructs a mask and a pixel map for the selected object. The mask is an array of blending parameters, and the pixel map contains natural foreground colors generated by removing background contributions form portions designated as combinations of foreground and background. A paste operation uses the blending parameters from the mask to add background contributions from a target images to the portions of the object designated as combinations of foreground and background.
