  • Patent number: 8494303
    Abstract: An image processing apparatus for automatically improving the contrast of an input image that is obtained from a digital camera or the like, and obtaining a sharper and clearing image. A contrast improvement unit performs a contrast improvement process on the input image by comparing an object pixel in the input image with pixels in the surrounding area. An image combination unit combines the enhanced image obtained by the contrast improvement process with the input image. The combined image is then output to a desired device such as a printer by an image output unit.

  • Patent number: 8165417
    Abstract: The invention provides a visual processing device that has a hardware configuration that does not depend on the visual processing to be achieved. A visual processing device 1 is provided with a spatial processing portion 2 and a visual processing portion 3. The spatial processing portion 2 performs predetermined processing with respect to an input signal IS that has been received as input, and outputs the result as an unsharp signal US. The visual processing portion 3 outputs an output signal OS, which is the input signal IS after visual processing, based on a two-dimensional LUT 4 that lists the relationship between the input signal IS that has been received as input and the unsharp signal US, and the output signal OS.
