After starting output of an audio guidance at a first volume, a control portion judges whether or not an image of a user is contained in image data, and also judges whether or not a cover has been opened, such that if no image of the user is contained in the image data and the cover is in a closed state, the control portion maintains the volume of the audio guidance at a first volume, whereas even if no image of the user is contained in the image data, when the cover is opened, the control portion changes the volume of the audio guidance to a second volume.

A semiconductor integrated circuit device with a balun which is formed above a conductive semiconductor substrate and which includes a dielectric film, an unbalanced line for transmitting an unbalanced signal, and balanced lines for transmitting a balanced signal. The unbalanced line is placed opposite to the balanced lines via a nano-composite film that is a region of the dielectric film. The nano-composite film, interposed between the unbalanced line and the balanced lines, has a relative permittivity higher than that of other regions of the dielectric film. This allows suppression of electromagnetic coupling of transmission lines or passive elements other than the balun, thereby providing a semiconductor device with a wide-band and small-size balun.
