  • Method and system for achieving communication between mobile device and electronic device
    Patent number: 9559772
    Abstract: A method and a system for achieving communication between a mobile device and an electronic device are disclosed. The system includes a mobile device, having a lighting unit, which modulates light beams therefrom with a message signal by a communicating mode; a light beam receiver, connected to or embedded in an electronic device, for receiving the modulated light beams and transforming the modulated light beams into an electric signal; and a demodulator, equipped in the electronic device, for demodulating the electric signal to get the message signal. Light beams are used as media to transmit signal from the mobile device to the electronic device.
    Type: Grant

  • [Automatic contrast limiting circuit and method thereof with spatial domain infinite impulse response filter]
    Patent number: 7324165
    Abstract: An automatic contrast limiting circuit and method thereof with spatial domain infinite impulse response filter are disclosed. A spatial domain infinite impulse response filter is adapted to generate an output value of the spatial domain infinite impulse response filter related to an input signal. A peak value detector is adapted to detect the peak output value of the spatial domain infinite impulse response filter during a predetermined recording interval. A contrast evaluator is used to evaluate the required contrast value referring to a predetermined threshold value and the output value of the spatial domain infinite impulse response filter.
