  • Patent number: 8115858
    Abstract: A system and a method for acquiring a moving image are provided. The system includes an image capturing unit capturing two images having different exposure times at a predetermined time slot, an image storing unit storing at least one of two images which were captured at a time slot previous to the predetermined time slot and which have different exposure times, an output image generating unit generating an output image by synthesizing the two images captured at the predetermined time slot or by synthesizing any one of the two images captured at the predetermined time slot and any one of the two images captured and stored at the previous time slot, an exposure time calculating unit receiving the images captured at the predetermined time slot and setting exposure times for a next time slot, and an exposure time storing unit storing the exposure times for the next time slot.

  • Patent number: 7433104
    Abstract: A method and an apparatus for adaptively enhancing a color of an image are provided. The apparatus includes a saturation component deriving unit, a saturation enhancement function determining variable calculator, a saturation enhancement unit, and a saturation component synthesizing unit. The saturation component deriving unit derives a saturation component from an input image. The saturation enhancement function determining variable calculator determines a saturation enhancement function used to enhance the saturation of the input image based upon a predetermined reference value. The saturation enhancement unit changes the derived saturation component using the saturation enhancement function. The saturation component synthesizing unit synthesizes the changed saturation component and other components of the input image and generates an output image based upon the synthesized components.
