  • Patent number: 8072507
    Abstract: A method of generating a high dynamic range image corresponding to a specific scene. The method includes shooting a specific scene to generate a base image; selecting a bright area and a dark area from the base image; determining base luminance according to the base image; shooting the specific scene to generate at least a first image, wherein average luminance of a part of the first image corresponding to the bright area of the base image is less than or equal to the base luminance; shooting the specific scene to generate at least a second image, wherein average luminance of a part of the second image corresponding to the dark area of the base image is greater than or equal to the base luminance; and combining at least the first image and the second image into a high dynamic range image corresponding to the specific scene.

  • Patent number: 7911532
    Abstract: The notebook computer includes a base and an upper cover. The base has a keyboard. The upper cover includes a screen, an image pickup device and a close-up lens. The upper cover is rotatable with respect to the base such that the image pickup device is able to capture an image of a document on a working plane. After the document image is obtained by the image pickup device, a built-in image processing program performs correction on the document image so as to obtain a corrected document image.

  • Publication number: 20090262204
    Abstract: The present invention relates to a notebook computer for capturing an image of a card. The notebook computer includes a base and an upper cover. The base includes a keyboard and a fixing recess for fixing the card. The upper cover is pivotally coupled to the base and includes an image sensing device and a screen for displaying a frame. If the image sensing device is disenabled to capture the image of the card, the frame on the screen has a first luminance value. Whereas, if the image sensing device is enabled to capture the image of the card, the frame on the screen has a second luminance value greater than the first luminance value.
