A method of determining a road surface condition includes: acquiring, when determining a condition of a road surface being in contact with a tire from a time-varying waveform of vibration of the running tire, the time-varying waveform of vibration having been detected by a vibration detecting means, a plurality of intrinsic vibration modes, from data of the time-varying waveform of vibration of the tire, using an algorithm of empirical mode decomposition; selecting an arbitrary intrinsic vibration mode from the plurality of intrinsic vibration modes; calculating a statistic amount from the distribution of feature data calculated by performing Hilbert transform on the selected intrinsic vibration mode to set the statistic amount as a feature amount; and determining the road surface condition from the feature amount and a feature amount obtained in advance for each road surface condition.

A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.
