Patent number: 8891017Abstract: A video input section acquires a video signal formed of a plurality of frames. A frame separator separates the video signal acquired by the video input section on a frame basis and distributes the separated video signals. A plurality of parallel processors perform video processing in parallel on the separated video signals corresponding to the frames separated and distributed by the frame separator. A frame combiner combines the separated video signals on which the plurality of parallel processors have performed the video processing.Type: GrantFiled: December 20, 2013Date of Patent: November 18, 2014Assignee: Seiko Epson CorporationInventor: Kazuyoshi Kegasawa

Patent number: 8878997Abstract: A visual display includes at least a first canvas configured to display a first session on the display and a second canvas configured to display a second session on the display. The first session includes first content received from a first content source and the second session includes second content having subject matter associated with the first content. The display includes a user agent configured to determine that the first content of the first session is associated with the second content of the second session and to pair the first and second canvases such that the first content and the second content are synchronized to each other.Type: GrantFiled: March 11, 2013Date of Patent: November 4, 2014Assignee: Sony CorporationInventors: Graham Clift, Brant Candelore, Kazumoto Kondo, Steven Richman, Fred Zustak

Patent number: 8704952Abstract: A video decoder that separates and analyzes analog video signals includes a hue and saturation separator and a video signal determiner. The hue and saturation separator demodulates from a component video signal chroma signal, which includes a hue signal and a saturation signal. The video signal determiner determines at least one video signal characteristic of the component video signal dependent on the hue and saturation signal. The video signal determiner may include a mode determiner that determines the encoding standard of the video signal, and a color burst determiner that determines a location of a color burst signal with the video signal. The mode determiner may include a signal lock detector, a sequence matcher, and an encoding mode selector. The color burst determiner may include an absolute value determiner and a burst position determiner.Type: GrantFiled: September 30, 2011Date of Patent: April 22, 2014Assignee: STMicroelectronics International N.V.Inventor: Ravindranath Ramalingaiah Munnan

Patent number: 8648965Abstract: An image signal processor and a method for processing an image signal thereof are disclosed. When the image signal processor executes an automatic chroma gain control (ACC), the image signal processor adjusts a variable rate of ACC gain according to a size of an input color signal to reduce a time for processing the ACC. Even if a difference between the size of the input color signal and the size of a reference color signal is large, the ACC is rapidly processed. As a result, transient phenomenon disappears from a screen.Type: GrantFiled: January 17, 2008Date of Patent: February 11, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Hye-joung Park

Patent number: 8212923Abstract: SECAM line identification in an analog television includes an accumulator that accumulates a FM demodulated output corresponding to a color reference tone for each SECAM line; a first leakage average filter receiving a first result from the accumulator; a second leakage average filter receiving a second result from the accumulator; and a line decision block comparing the first result and the second result. An apparatus for soft-decision based PAL switch detection in an analog television includes a burst locked oscillator (BLO) receiving a composite video signal as input and producing an instantaneous PAL switch signal for each line; a leakage average filter receiving the PAL switch signal and filtering noise from an output received from the BLO; and a switch detection block receiving a filtered output from the leakage average filter, and making a decision based on a sign of the filtered output of the leakage average filter.Type: GrantFiled: April 13, 2010Date of Patent: July 3, 2012Assignee: Newport Media, Inc.Inventor: Yongru Gu

Patent number: 5469218Abstract: An image signal processing device according to this invention is a device for processing an image signal. The device is arranged to input digital data corresponding to two kinds of color-difference signals in synchronism with a clock signal corresponding to a data rate of the digital data, reconstruct the inputted digital data corresponding to the two kinds of color-difference signals into digital data synchronized with a clock signal having a frequency which is an integer multiple of a color subcarrier frequency, and form digital data corresponding to a chrominance signal by using the reconstructed digital data corresponding to the two kinds of color-difference signals. Accordingly, it is possible to stably encode the two kinds of color-difference signals into the carrier chrominance signal by means of a simple construction without degrading the color-difference signals.Type: GrantFiled: July 20, 1992Date of Patent: November 21, 1995Assignee: Canon Kabushiki KaishaInventors: Yuji Sakaegi, Eiji Ohara
