Patent number: 8849011Abstract: A method is used for compensating a boundary of an image, in which each scan line in the image is shifted by a corresponding line shift amount. The method determines a boundary region for the image and moves each pixel in a scan line from an original position to a new position within the boundary region, in which the new position is determined according to the width of the boundary region, the original position, and a line shift amount, and the scan line is shifted by the line shift amount. Then, the method interpolates at least one pixel into the scan line according to the moved pixels for generating a compensated image.Type: GrantFiled: October 7, 2010Date of Patent: September 30, 2014Assignee: Himax Media Solutions, Inc.Inventor: Wei-Ting Suen

Patent number: 8457398Abstract: An image enhancement apparatus is provided. The image enhancement apparatus includes a global contrast curve generator, a local contrast curve generator and an image generator. The global contrast curve generator generates a global contrast curve for an input image according to a global histogram of the input image. The local contrast curve generator generates a local contrast curve for each image partition within the input image according to the global contrast curve and further a feature of the image partition. The image generator generates an output image by enhancing a contrast of each image partition according to the local contrast curve for the image partition and the input image, and merging the enhanced image partitions.Type: GrantFiled: October 27, 2009Date of Patent: June 4, 2013Assignee: Himax Media Solutions, Inc.Inventors: Wei-Ting Suen, Shing-Chia Chen

Patent number: 8345070Abstract: A method for frame rate up conversion. The method is executed by a frame rate up-converter. The frame rate up-converter receives a plurality of consecutive input video frames and detects luminance information for a current frame. The frame rate up-converter generates a first output frame according to the luminance information for the current frame and a preceding frame before the current frame and generates a second output frame according to the luminance information for the current frame and a succeeding frame after the current frame, wherein the second output frame is outputted after the first output frame.Type: GrantFiled: June 10, 2009Date of Patent: January 1, 2013Assignee: Himax Media Solutions, Inc.Inventors: Wei-Ting Suen, Ling-Hsiu Huang, Lin-Kai Bu

Publication number: 20120069038Abstract: An image display system including an adjuster, a first analysis module, a second analysis module and a brightness compensation module is disclosed. The adjuster utilizes a specific method and a depth information to adjust a processed image to generate a first image and a second image. The first analysis module analyzes the first image to obtain a first image distribution result. The second analysis module analyzes the second image to obtain a second image distribution result. The brightness compensation module adjusts brightness of the first and the second images according to the first and the second image distribution results. The adjusted first image serves as a left-eye image component and the adjusted second image serves as a right-eye image component.Type: ApplicationFiled: September 20, 2010Publication date: March 22, 2012Applicant: HIMAX MEDIA SOLUTIONS, INC.Inventors: Wei-Ting Suen, Ling-Hsiu Huang
