Patent number: 9203514Abstract: According to one embodiment, a transmission system includes a transmitter and a receiver. The transmitter includes a modulator configured to modulate transmission data at a chip rate to generate a modulation signal, and one or a plurality of light sources configured to emit visible light according to the modulation signal. The receiver includes a light receiver having one or more lines of light receiving elements to receive light in a first range including the visible light; and a demodulator configured to demodulate image data generated according to the light received by the light receiver to generate reception data corresponding to the transmission data. A following equation is satisfied ff<fm where fm is the chip rate, and ff is a frame rate of the light receiver.Type: GrantFiled: February 28, 2013Date of Patent: December 1, 2015Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Jun Deguchi, Hideaki Majima, Toshiyuki Yamagishi, Nau Ozaki, Ichiro Seto, Koji Horisaki, Masahiro Sekiya, Hideki Yamada, Yuki Fujimura

Patent number: 8879917Abstract: According to one embodiment, a transmission system includes a transmitter, and a receiver. The transmitter includes one or a plurality of light sources, a modulator, a first driver, a display, and a second driver. The one or a plurality of light sources is configured to emit a visible light whose light amount corresponds to a first drive signal. The modulator is configured to, according to transmission data to be transmitted from the transmitter to the receiver, modulate a first luminance signal indicative of an amount of the light the light source is configured to emit, to generate a second luminance signal. The first driver is configured to generate the first drive signal based on the second luminance signal. A mean of the second luminance signal during one frame in the input video signal is substantially equal to a value of the first luminance signal in the frame.Type: GrantFiled: August 30, 2012Date of Patent: November 4, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Jun Deguchi, Hideaki Majima, Yuichi Nakamura, Hisao Kawasato, Nau Ozaki, Toshiyuki Yamagishi

Publication number: 20130251375Abstract: According to one embodiment, a receiver includes an image sensor, a synchronization controller, and a data generator. The image sensor detects a visible ray having a lattice-shaped emission pattern. The synchronization controller determines whether it is necessary to generate data based on a first synchronized visible ray located at a first lattice corner of the emission pattern and a second synchronized visible ray located at a second lattice corner. The second lattice corner is an opposite corner to the first lattice corner. The data generator generates the data corresponding to a data visible ray located at a lattice point other than the first lattice corner and the second lattice corner when the synchronization controller determines that it is necessary to generate the data.Type: ApplicationFiled: August 31, 2012Publication date: September 26, 2013Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Nau Ozaki, Jun Deguchi, Hideaki Majima, Toshiyuki Yamagishi
