摘要： According to an embodiment, a semiconductor integrated circuit includes an amplifier, an interference wave suppression unit, a coupler and a filter control circuit. The interference wave suppression unit includes a filter being controlled to be on or off. The filter is configured to suppress an interference wave component of an amplified signal to output the signal as an output signal when the filter is on. The coupler is configured to detect an input signal or the output signal. The filter control circuit controls the filter to be on when a signal level of a detection input signal or a detection output signal detected by the coupler is greater than or equal to a reference value, and controls the filter to be off when the signal level is smaller than the reference value, at arbitrary determination timing in a period of time between a transmission and a reception.

摘要： 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.

摘要： 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.
