Patent number: 11451740Abstract: A video-image-interpolation apparatus is provided, which includes at least three image-layering circuits, at least three motion-estimation circuits, a motion-estimation-filtering circuit, a motion-compensated frame-interpolation circuit, and a display-control circuit. Each motion-estimation circuit performs motion estimation on a reference image-layer sequence and a reference subtitle-layer sequence that are generated from an input video signal by each image-layering circuit. The motion-estimation-filtering circuit adaptively determines the motion-estimation circuit having the smallest motion error.Type: GrantFiled: November 10, 2021Date of Patent: September 20, 2022Assignee: TERAWINS, INC.Inventors: Yu-Kuang Wang, Wen-Yi Huang, Pei-Kai Hsu

Patent number: 10616542Abstract: A multi-dimensional image projection apparatus is provided. The multi-dimensional image projection apparatus includes an image projector and an image-processing circuit. The image-processing circuit is configured to receive an input image, and perform a linearity transformation process and a first inverse image warping process on the input image according to sensor information about the multi-dimensional image projection apparatus relative to the projection surface to generate a first image. The image-processing circuit performs a matrix transformation process and a second inverse image warping process on the first image according to the sensor information to generate a second image, and generate an output image according to the second image. The image projector projects the output image onto the projection surface.Type: GrantFiled: February 12, 2018Date of Patent: April 7, 2020Assignee: Terawins, Inc.Inventors: Yu Kuang Wang, Wen Yi Huang, Pei Kai Hsu, Wei Ya Wu

Publication number: 20140022383Abstract: A surveillance system, an image compression serializer and an image decompression deserializer are disclosed. The Surveillance System includes a video camera, a coaxial cable and a central control machine. The video camera provides a real time record and has an image compression serializer which compresses a digital image, captured by the video camera, down to a specific resolution and converts the digital image of the specific resolution into a serial format. The coaxial cable couples the image compression serializer to an image decompression deserializer of the central control machine. The digital image in the specific resolution and serial format is conveyed to the image decompression deserializer to be converted into a parallel format and decompressed to be video encoded.Type: ApplicationFiled: May 22, 2013Publication date: January 23, 2014Applicant: TERAWINS, INC.Inventors: Wen-Yi HUANG, Hsi-Pang WEI, Yu-Kuang WANG

Patent number: 7432980Abstract: The present invention provides a method for reducing analog PLL (Phase-lock loop) jitter in video ADC application. The HSync/CSync is replaced with a faked HSync signal to be inputted to PLL during vertical blank period. Therefore the analog PLL will only see the faked HSync signal of fixed period as a line-lock trigger signal, while no COAST signal is required. Also, the faked HSync is fine-tuned to match with the external HSync/CSync leading edge to minimize PLL jitter.Type: GrantFiled: August 5, 2005Date of Patent: October 7, 2008Assignee: Terawins, Inc.Inventors: Cyrus Chu, Wen Yi Huang

Publication number: 20060280269Abstract: The present invention is to provide a method for designing a video and image scaler based on 2-D Finite Impulse Response (FIR) filter. First, a 2-D video/image source is sampled with sampling rate higher than Nyquist rate to obtain 2-D samples; second, zeros are padded in between the 2-D samples to get a zero padding image; third, the zero padding image is passed through a 2-D FIR filter and a scaled-up image is obtained.Type: ApplicationFiled: June 8, 2005Publication date: December 14, 2006Applicant: Terawins, Inc.Inventor: Wen-Yi Huang
