Publication number: 20180376157Abstract: An image processing apparatus receives input of an original image that is divided into at least two partial images in a top-and-bottom direction. The image processing apparatus adds a first line number of dummy screen lines to a top portion of a partial image that is a top portion of the original image. The image processing apparatus adds a second line number of dummy screen lines to a lower portion of a partial image that is a lower portion of the original image. The image processing apparatus uses a z×z encoding process unit and performs an encoding process for each of the partial images to which the dummy screen lines have been added.Type: ApplicationFiled: August 31, 2018Publication date: December 27, 2018Inventor: Tatsushi OTSUKA

Patent number: 7652503Abstract: A semiconductor device includes an external pin, a control parameter decision circuit, and a register update circuit. The control parameter decision circuit includes a register and an output selector. The register is initialized in accordance with resetting of the semiconductor device. The output selector, according to a level value of an external input signal supplied via the external pin, selects one of a signal whose level value is set equal to a register value of the register and a signal whose level value is set opposite to the register value of the register, and outputs the selected signal as a control parameter signal. The register update circuit updates the register value of the register when a level value of the control parameter signal need be changed.Type: GrantFiled: December 26, 2006Date of Patent: January 26, 2010Assignee: Fujitsu Microelectronics LimitedInventors: Hidenari Nagata, Masanori Ishizuka, Tatsushi Otsuka

Patent number: 7533192Abstract: The invention provides a task scheduling method which can prevent overflowing of a buffer on a host system or a data encoding/decoding apparatus even when the transfer rate falls in case the compressed data and the non-compressed data are simultaneously transferred between the host system and the data encoding/decoding apparatus. In a task scheduling method, the compressed audio/video data is transferred from the buffer of the host system to an external device with a first transfer priority. The non-compressed audio/video data is transferred from the buffer to the external device with a second transfer priority lower than the first transfer priority.Type: GrantFiled: March 8, 2005Date of Patent: May 12, 2009Assignee: Fujitsu Microelectronics Ltd.Inventors: Tatsushi Otsuka, Tetsu Takahashi

Patent number: 7471722Abstract: A video encoding device capable of performing a near-real-time encoding process while restraining deterioration in image quality. A first encoding section encodes a video signal to generate a first stream and extracts stream information including space- and time- related information of the video signal. A stream buffer stores video scenes of the first stream which correspond to a partial time of the video signal. An encoding control section analyzes a code generation rate and motion information from the stream information to generate encoding control information. A second encoding section encodes the first stream read from the stream buffer, in accordance with the encoding control information, to generate a second stream. The stream buffer stores multiples video scenes of the first stream by means of which a scene change can be detected as an information rate change.Type: GrantFiled: December 29, 2004Date of Patent: December 30, 2008Assignee: Fujitsu LimitedInventors: Takahiko Tahira, Tatsushi Otsuka
