Patent number: 7675573Abstract: Global-adaptive deinterlacing systems and methods for reducing scintillation and feathering artifacts. Motion adaptive deinterlacing (MADI) local motion quantization thresholds are adaptively adjusted according to the amount of global motion present in the video sequence, thereby minimizing scintillation and feathering artifacts when deinterlacing the fields. A set of global motion scenarios are defined for the purpose of classifying fields, and a number of global motion indicators are used to detect on a field-by-field basis different global motion scenarios.Type: GrantFiled: January 12, 2006Date of Patent: March 9, 2010Assignee: Genesis Microchip Inc.Inventors: Eduardo Rogelio Corral Soto, Peter Swartz, Andrew MacKinnon

Publication number: 20080037627Abstract: Disclosed herein are methods and apparatus, including computer program products, implementing and using techniques for reducing mosquito noise and blockiness in an image frame of a video signal. A border of a pixel block is determined, and if the region surrounded by the border is determined to be associated with mosquito noise or blockiness, then the mosquito noise or blockiness, respectively, is reduced in the region only.Type: ApplicationFiled: June 5, 2007Publication date: February 14, 2008Applicant: GENESIS MICROCHIP INC.Inventors: Tianhua Tang, Peter Swartz, Xu Dong

Publication number: 20060251323Abstract: A method, system and apparatus for color management that directly acts upon the hue, saturation, and luminance value of a pixel instead of its U and V value. Additionally, instead of dividing the color space into uniform areas, the color space is divided into multiple user-defined regions. The detection of a pixel is based on its hue, saturation, and luminance value, so a single set of values can define the correction for an entire hue.Type: ApplicationFiled: January 24, 2006Publication date: November 9, 2006Applicant: Genesis Microchip Inc.Inventors: Andrew MacKinnon, Peter Swartz

Publication number: 20060077306Abstract: Frequency content motion detection is performed by decomposing a raw field luminance data in to a number of frequency content sub-bands, detecting motion using the raw field luminance data in parallel with the decomposing, generating a motion correction value by multiplying absolute values of the sub-bands by weighting factors, and applying the motion correction value to detected motion.Type: ApplicationFiled: September 27, 2005Publication date: April 13, 2006Applicant: Genesis Microchip Inc.Inventors: Jayakanth Suyambukesan, Peter Swartz, Xu Dong

Publication number: 20050134735Abstract: A multi-function display controller that includes a source detector unit for determining if the source of an input stream is either film originated source originated or video source originated. A source converter unit for converting the input image stream to a common signal processing format is coupled to the source detector unit. Once converted to the common signal processing format, a determination is made if the input image stream is interlaced or non-interlaced (progressive scan). If the input image stream is interlaced, a de-interlace unit converts the interlaced signal to progressive scan using either motion adaptive or motion compensated de-interlacing techniques. It should be noted that in the described embodiment, motion vectors generated for use by the motion compensated de-interlace can be optionally stored in a memory unit for use in subsequent operations, such as motion compensated frame rate conversion or noise reduction (if any).Type: ApplicationFiled: December 3, 2004Publication date: June 23, 2005Applicant: Genesis Microchip Inc.Inventor: Peter Swartz

Patent number: 5291280Abstract: A motion detector generates a field motion detection signal from information contained in adjacent fields of a two-to-one interlaced format video signal. The motion detector comprises an input for receiving the video signal from a source, a first delay for delaying the video signal at the input by one field period less one half of one scanning line period and for providing a first delayed output, a second delay for delaying the video signal at the input by one field period plus one half of one scanning line period and for providing a second delayed output, a first subtraction circuit for subtracting the first delayed output from the video signal to provide a first difference, a second subtraction circuit for subtracting the second delayed output from the video signal to provide a second difference, and a comparison circuit for comparing the first difference with the second difference and for putting out a selected one thereof having a lesser absolute magnitude as the field motion detection signal.Type: GrantFiled: May 5, 1992Date of Patent: March 1, 1994Inventors: Yves C.
