Patent number: 10244162Abstract: A directionality control system includes: a camera; a microphone provided as a separate body from the camera; a display that displays video data captured by the camera; and a processor that computes a sound collection direction, which is directed from the microphone toward a sound position corresponding to a designated position in the video data. The processor computes the sound collection direction by using parameters including: a first height of the camera from a reference surface, a second height of the microphone from the reference surface, a third height of a computation reference point from the reference surface, the computation reference point being positioned in the sound collection direction at a position different from the sound position, a direction which is directed from the camera toward the sound position, and a fourth height of the sound position from the reference surface.Type: GrantFiled: December 4, 2017Date of Patent: March 26, 2019Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hirotaka Sawa, Toshimichi Tokuda, Shinichi Shigenaga, Shuichi Watanabe, Shojiro Matsuo, Takashi Hirabara, Tadashi Maki, Hisashi Tsuji, Teppei Fukuda, Akitoshi Izumi, Shintaro Yoshikuni, Hiroyuki Matsumoto, Kazunori Hayashi, Kosuke Shinozaki

Publication number: 20180115760Abstract: A sound and video processing system includes: a display, having a rectangular display region, that displays a video image in a circular video-image display region smaller than the rectangular display region; and a sound collector that collects sound. A processor generates emphasized audio data, in which sound is emphasized in at least one direction from a position of the sound collector toward at least one position corresponding to at least one designated location in the video image. In response to receiving designation outside the video-image display region, the processor displays a state display area or an adjustment operation area for the sound to be output from the speaker in a rectangular region which has a diagonal line extending from one of four corners of the rectangular display region to a center of the video-image display region and intersecting with a boundary line of the video-image display region.Type: ApplicationFiled: October 13, 2017Publication date: April 26, 2018Applicant: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LT D.Inventors: Hirotaka SAWA, Shinichi SHIGENAGA, Toshimichi TOKUDA, Shintaro YOSHIKUNI, Shuichi WATANABE, Tadashi MAKI, Hirokazu TASAKA, Susumu ONO, Keisuke FUJIMOTO, Shojiro MATSUO, Teppei FUKUDA, Hiroyuki MATSUMOTO, Akitoshi IZUMI, Hisashi TSUJI, Kazunori HAYASHI, Ryoichi YUGE

Publication number: 20180115759Abstract: A sound and video processing system includes: a display that displays a video image captured by the camera; a sound collector that collects sound; an input device that receives designation of at least one designated location in the video image displayed on the display. A processor generates emphasized audio data, in which sound is emphasized in at least one direction from a position of the sound collector toward at least one position corresponding to the at least one designated location. The processor displays at least one identification shape at the at least one designated location. In response to receiving re-designation of one of the at least one designated location by the input device, the processor outputs audio data in which emphasis of sound stops in a direction from the position of the sound collector toward the position corresponding to the re-designated location.Type: ApplicationFiled: October 13, 2017Publication date: April 26, 2018Applicant: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hirotaka SAWA, Shinichi SHIGENAGA, Toshimichi TOKUDA, Shintaro YOSHIKUNI, Shuichi WATANABE, Tadashi MAKI, Hirokazu TASAKA, Susumu ONO, Keisuke FUJIMOTO, Shojiro MATSUO, Teppei FUKUDA, Hiroyuki MATSUMOTO, Akitoshi IZUMI, Hisashi TSUJI, Kazunori HAYASHI, Ryoichi YUGE

Patent number: 9860439Abstract: Sound collection directionality is formed toward a location corresponding to a position designated in a video of a predetermined region which is imaged by a camera apparatus with a microphone array apparatus as a reference, and audio data is collected with high accuracy. In a directionality control system (10), a signal processing unit (33) derives a sound collection direction (?MAh,?MAv) which is directed from an installation position of a microphone array apparatus (2) toward a sound position corresponding to a position designated in video data on a screen of the display device (36) in response to a user's designation of any position in the video data displayed on the screen. The signal processing unit (33) forms sound collection directionality of audio data in the derived sound collection direction (?MAh,?MAv).Type: GrantFiled: February 14, 2014Date of Patent: January 2, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hirotaka Sawa, Toshimichi Tokuda, Shinichi Shigenaga, Shuichi Watanabe, Shojiro Matsuo, Takashi Hirabara, Tadashi Maki, Hisashi Tsuji, Teppei Fukuda, Akitoshi Izumi, Shintaro Yoshikuni, Hiroyuki Matsumoto, Kazunori Hayashi, Kosuke Shinozaki

Patent number: 9826211Abstract: A recorder receives designation of a video which is desired to be reproduced from a user. If designation of one or more designated locations where sound is emphasized on a screen of a display which displays the video is received by the recorder from the user via an operation unit during reproduction or temporary stopping of the video, a signal processing unit performs an emphasis process on audio data, that is, the signal processing unit emphasizes audio data in directions directed toward positions corresponding to the designated locations from a microphone array by using audio data recorded in the recorder. A reproducing device reproduces the emphasis-processed audio data and video data in synchronization with each other.Type: GrantFiled: December 27, 2013Date of Patent: November 21, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hirotaka Sawa, Shinichi Shigenaga, Toshimichi Tokuda, Shintaro Yoshikuni, Shuichi Watanabe, Tadashi Maki, Hirokazu Tasaka, Susumu Ono, Keisuke Fujimoto, Shojiro Matsuo, Teppei Fukuda, Hiroyuki Matsumoto, Akitoshi Izumi, Hisashi Tsuji, Kazunori Hayashi, Ryoichi Yuge

Patent number: 9516412Abstract: A directivity control apparatus controls a directivity of a sound collected by a sound collecting unit including a plurality of microphones. A beam forming unit forms a beam in a direction from the sound collecting unit toward a sound source corresponding to a position designated in an image on a display unit. A magnification setting unit sets a magnification for magnifying or demagnifying the image in the display according to an input. The beam forming unit also changes a size of the formed beam in accordance with the magnification set by the magnification setting unit.Type: GrantFiled: March 28, 2014Date of Patent: December 6, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Shinichi Shigenaga, Shuichi Watanabe, Tadashi Maki, Akitoshi Izumi, Kazunori Hayashi, Toshimichi Tokuda, Shojiro Matsuo, Hirotaka Sawa
