Abstract: In a sound output device, a sound input unit acquires a sound signal reproduced by a reproduction device. A beat extractor extracts a beat component of the sound signal based on a spectrogram, and generates a beat waveform having information of a beat timing and a beat intensity. An output signal generator amplifies the sound signal with the beat waveform being a gain, using the beat timing and beat intensity which the beat waveform has. A sound output unit outputs the beat enhanced sound signal as a sound by performing D/A conversion on the beat enhanced sound signal.

Abstract: Provided is a torque detection apparatus including a base portion, a drive portion, and a detection portion. The drive portion includes a rotor having a main axis in a direction of a first axis, and a stator configured to rotate the rotor around the main axis. The detection portion includes a strain body and a detection element. The strain body includes a first end portion to be fixed to the base portion and a second end portion to be fixed to the rotor, and is arranged concentrically with the rotor. The detection element is provided to the strain body so as to detect a strain of the strain body around the first axis with respect to the base portion.

Abstract: A mobile device including a solar battery having a light-receiving surface provided on a casing of the mobile device, an illuminance detector that detects an illuminance of light incident on the casing, an output section that outputs a state of light incident on the light-receiving surface of the solar battery, and a controller that controls the output section based on the illuminance detected by the illuminance detector.

Abstract: A replacement area is set within an image expressed with captured image data. A pixel area with image content that can be processed without greatly altering the entire image content, for instance, may be designated as the replacement area. Replacement image data are generated by executing processing for replacing all of or part of the pixel data in the replacement area with insertion image data. The insertion image data are image data containing text, graphics or the like, such as an advertisement, a message or a translation. Consequently, various types of information can be provided in the replacement image data, a message from the user can be incorporated in the replacement image data, or better user convenience can be assured through the replacement image data.
