  • Publication number: 20200380554
    Abstract: An image playback unit 11 playing back a three-dimensional spatial image including a plurality of objects, an attention object detection unit 12 detecting an object that a viewer pays attention to from the three-dimensional spatial image that is played back, an attention degree calculation unit 13 calculating an attention degree of the viewer with respect to the object, and a region evaluation unit 14 evaluating a degree of effect of an advertising display region to be disposed in the vicinity of the object, in accordance with the calculated attention degree are provided. Since an advertising display region to be disposed in the vicinity of an object having a higher attention degree from the viewer is more likely to be seen from the viewer, a degree of effect of the advertisement therein is highly evaluated. Thereby, it is possible to know the effect extent when an advertisement is presented in the advertising display region.

  • Patent number: 10277328
    Abstract: A signal processing device processes an electric field information signal indicating a polarization multiplexed optical signal in which different modulation formats are used. A first optical signal transmitted in a first polarization component and a second optical signal transmitted in a second polarization component are multiplexed in the polarization multiplexed optical signal. The signal processing device includes a generator and a compensation circuit. The generator selects the first polarization component or the second polarization component based on modulation formats of the first and second optical signals, and generates a compensation value for compensating for an electric field information signal of a selected polarization component based on the electric field information signal of the selected polarization component. The compensation circuit compensates for electric field information signals of the first and second polarization components using the compensation value generated by the generator.

  • Patent number: 10219049
    Abstract: An optical reception apparatus includes an equalization processor, an extraction unit, a first ratio calculator, and an instruction transmitter. The equalization processor suppresses fluctuations in amplitude of an electrical signal obtained by converting an optical signal including a plurality of pilot symbols subjected to BPSK modulation by an optical transmission apparatus. The extraction unit extracts the pilot symbols from the electrical signal with suppressed fluctuations in amplitude. The first ratio calculator calculates a ratio of an amplitude component to a phase component of each of the pilot symbols extracted by the extraction unit. The instruction transmitter transmits information relating to skew adjustment based on the ratio of the amplitude component to the phase component calculated by the first ratio calculator for each of different control values to the optical transmission apparatus.
