Patent number: 8284306Abstract: An image signal processing unit includes a frame rate conversion circuit performing double frame rate conversion on an input image signal from a first frame frequency to a second frame frequency. When performing frame rate conversion with the motion correction process, a motion vector is determined between a first frame image and a third frame image, and three interpolation frame images are formed through the motion correction process to the first frame image based on the motion vector, and are inserted between the first and third frame images so as to establish the second frame frequency. When performing frame rate conversion without the motion correction process, an interpolation frame image same as the first frame image is inserted between the first and second frame images, and an interpolation frame image same as the second frame image is inserted between the second and third frame images.Type: GrantFiled: August 3, 2009Date of Patent: October 9, 2012Assignee: Sony CorporationInventors: Takaya Hoshino, Shinichiro Miyazaki, Seiko Imai

Patent number: 8213504Abstract: The present invention provides an image display apparatus capable of suppressing deterioration in picture quality resulting from precision of detection of a motion vector at the time of performing a predetermined video signal process to improve picture quality. In consideration of reliability in detection of a motion vector mv by a motion vector detector 44, a video signal process in an interpolation section 45, an imaging blur suppression processor 13, and an overdrive processor 10 is performed. Concretely, the video signal process is performed so that a degree of the video signal process rises as reliability increases and, on the other hand, a degree of the video signal process falls off as the reliability decreases. In the case of performing the video signal process using a motion vector, even when a motion vector lies out of a motion vector search range (block matching range), the video signal process according to the motion vector detection precision can be performed.Type: GrantFiled: February 20, 2008Date of Patent: July 3, 2012Assignee: Sony CorporationInventors: Shinichiro Miyazaki, Ichiro Murakami, Toru Nishi

Patent number: 7324742Abstract: Apparatus to suppress image deterioration in a data, broadcast thereby providing a display with quality, wherein a video signal separated from a reception signal by a demultiplexer is outputted to a converter section through an MPEG decoder section. When the video signal is a data broadcast and in a 480I signal format, a CPU controls a converter section to perform size-scaling on the video signal and to convert it into a 480p signal format. A data processing section generates a video signal having a 480p signal format of a corresponding character or figure, under control of the CPU, on the basis of a data signal. A synthesizer section synthesizes together the two video signals processed by the converter section and data processing section and inputs the synthesized signal to a D/A converter. The D/A converter converts an input video signal into an analog signal and outputs it to a display unit.Type: GrantFiled: June 21, 2002Date of Patent: January 29, 2008Assignee: Sony CorporationInventor: Shinichiro Miyazaki
