Patent number: 9179065Abstract: An image processing apparatus includes: an imaging device; a main memory that stores motion picture data acquired by the imaging device; a motion picture compressing unit that compresses the motion picture data stored in the main memory; a still image frame acquiring unit that acquires a still image frame at arbitrary timing from the motion picture data acquired by the imaging device; a line memory that stores still image data that is a part of the still image frame acquired by the still image frame acquiring unit; and a still image compressing unit that performs a compression process of the still image data stored in the line memory. The still image compressing unit compresses the still image data in real time. The main memory stores the motion picture data and stores compressed data that is compressed in real time by the still image compressing unit.Type: GrantFiled: August 13, 2013Date of Patent: November 3, 2015Assignee: JVC KENWOOD CorporationInventors: Norio Kurashige, Takashi Kiyofuji, Kouji Tanaka

Patent number: 6295316Abstract: An automatic equalization system includes an analog-to-digital converter for periodically sampling an analog signal representative of digital information in response to a sampling clock signal, and for converting every sample of the analog signal into a corresponding digital sample to convert the analog signal into a corresponding digital signal. A first device operates for detecting a phase error of the sampling clock signal in response to a correlation between samples of the digital signal generated by the analog-to-digital converter. A second device operates for controlling a frequency of the sampling clock signal in response to the phase error detected by the first device. A variable filter operates for subjecting the digital signal generated by the analog-to-digital converter to a variable filtering process to convert the digital signal generated by the analog-to-digital converter into a filtering-resultant signal. The filtering process corresponds to a waveform equalization process.Type: GrantFiled: May 20, 1998Date of Patent: September 25, 2001Assignee: Victor Company of Japan, Ltd.Inventors: Junichiro Tonami, Takashi Kiyofuji

Patent number: 5301027Abstract: In a method of superimposing data of a character (mark) on video data, the superimposed video data being subjected to a data compression processing for extracting video data within each of blocks from one frame of the superimposed video data and for data-compressing the extracted video data, the blocks forming one frame, the each block including a predetermined number of two-dimensionally arranged pixels of the superimposed video data, a position of the character superimposed on the video data with respect to a lump of the blocks, where the character is to be imposed, is determined such that the number of blocks over which the character spreads is minimized when a size and a shape of the character or the mark are unchanged.Type: GrantFiled: March 23, 1993Date of Patent: April 5, 1994Assignee: Victor Company of Japan, Ltd.Inventors: Takashi Kiyofuji, Hiroshi Yamada, Kohsuke Kinoshita, Toshihiko Monma

Patent number: 5293225Abstract: A color camera apparatus comprises an image pickup element having a stripe/mosaic type color filter and photo-electrically converting an arriving optical image so as to obtain at least a signal including a brightness component and a color component multiplexed with each other. And, the apparatus comprises an A/D converter for digitizing above multiplexed signal, and a brightness signal processing circuit which separates the brightness component from the multiplexed signal and carries out an aperture correction by means of a delay element having a delay amount corresponding to two horizontal scanning period. And further, the apparatus comprises a color signal processing circuit which separates the color component from the multiplexed signal so as to obtain two line-sequential color difference components through a predetermined arithmetic procedure.Type: GrantFiled: May 28, 1992Date of Patent: March 8, 1994Assignee: Victor Company of Japan, Ltd.Inventors: Hiroshi Nishiyama, Shozo Yokoyama, Masanori Kubota, Takashi Kiyofuji, Mamoru Miyashita
