A secondary coupled vibration occurs between a hand portion of the user and a vehicle due to an influence of a direct vibration of the vehicle. The coupled vibration differs in a deflection width, and generation timing and peak timing of a vibration depending on user's various individual conditions. A difference amount calculation unit and a user-based characteristic learning unit analyze and store a correspondence relation of an acceleration and the coupled vibration, and thereby learn a characteristic of the coupled vibration corresponding to the user. The coupled vibration corresponding to the user can be detected with high accuracy by checking the detected acceleration against a learning result. A position of an indication point indicated by the hand of the user can be recognized with high accuracy by correcting a position of a captured image itself by element of the detected coupled vibration.

A receiver receives a multiplex broadcasting wave of a terrestrial wave and a satellite wave and executes AGC. As for the terrestrial wave, only a frequency band of the terrestrial wave is extracted by a filter for the terrestrial wave, and the AGC on the terrestrial wave side is executed through an AGC loop for the terrestrial wave. As for the satellite wave, the frequency band including the terrestrial wave and the satellite wave is extracted by the filter for the satellite wave, and the AGC is executed based on the signal. As a result, the AGC on the satellite wave side is affected by a receiving condition variation of the terrestrial wave. By a frequency-analysis of the terrestrial wave signal, the receiving condition of the terrestrial wave is analyzed. According to the analyzed result, an AGC adjusting quantity on the satellite wave side is determined and the AGC on the satellite wave side is adjusted by the adjusting quantity. Thereby, the effects on the satellite wave side by the receiving condition of the terrestrial wave signal may be reduced or eliminated, and appropriate AGC can be executed to the satellite wave.
