Patents by Inventor Ming-Fon Chien

Ming-Fon Chien has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8952882
    Abstract: Adjust a backlight of a display device according to image loading and edge statistics of an input image. When the input image is a dark scene and includes relatively more edges, a luminance of the backlight would be controlled according to the image loading of the input image and compensated the backlight for showing details of the input image clearly. When the input image is a dark scene with negligible edges, the luminance of the backlight would be controlled by image loading with no or few compensation for lowering the power consumption. When the input image is a bright scene, or when the input image includes no edge or only negligible edges, minimum compensation is applied to the backlight for lowering the power consumption.

  • Patent number: 8217888
    Abstract: A method for processing images in a liquid crystal display is provided. The method includes the steps of: acquiring a backlight index according to an image; adjusting a backlight according to the backlight index; acquiring a reference gray level according to the adjusted backlight, wherein the reference gray level lies in between a first gray level boundary and a second gray level boundary; transferring a gray level of the image into a corresponding output gray level according to the backlight index when the gray level of the image lying in between the reference gray level and the first gray level boundary; and transferring the gray level of the image into another corresponding output gray level according to a linear relationship when the gray level of the image lying in between the reference gray level and the second gray level boundary.

  • Publication number: 20110075043
    Abstract: In one aspect, the present invention relates to a method of processing images. In one embodiment, the method includes the steps of processing an image having a plurality of image pixels expressed in grey level values, GLIN(i), of n bits in a RGB color domain so as to obtain the maximum gray level value among the gray level values of all RGB colors of the plurality of image pixels, determining a color shift compensation coefficient, ?M, according to the maximum gray level value of the image, and transforming the image into an output image having grey level values, GLOUT(i), that satisfies the relationship of GLOUT(i)=?M×GLIN(i)?N.
