An electronic camera is provided with a touchscreen. When a cameraman touches the touchscreen on a principal subject in a captured image shown on the touchscreen, the touched portion is determined and the focus and exposure are adjusted in conformity with the principal subject. When the image is designated to be stored, positional information on the principal subject as well as image information is stored into a built-in memory or a detachable external memory. For this reason, wherever the principal subject is located on the image, the image-capturing is performed with favorable results. The positional information on the principal subject is utilized for printing or reproducing the image so as to perform image tone corrections such as correction of brightness and skin pigmentation in an area including the principal subject, so that a high-quality image can be printed or reproduced.

There are provided a mobile device that is equipped with a musical composition-reproducing section and capable of curtailing the battery drain as much as possible, and a mobile device that prevents the quality of reproduced musical tones from being degraded even if the voltage level of the battery lowers. A battery voltage detector monitors an voltage level of a battery. The musical composition-reproducing section is controlled such that the number of parts of the musical composition reproduced by the musical composition-reproducing section is reduced when the monitored voltage level of the battery becomes lower than a reference value. In other forms of the invention, when the monitored voltage level of the battery becomes lower than a reference value, a first predetermined number of parts of the musical composition data are assigned to intrinsic ones of a larger second predetermined number of parts that correspond to the first predetermined number of parts of said musical composition, as well as to other ones of the second predetermined number of parts than the intrinsic ones, for reproduction of the musical composition, or the gain of a variable-gain amplifier is increased to compensate for the lowering of the volume of the reproduced parts.

A laser scanner for optically scanning and measuring an environment comprises a light transmitter having a predetermined transmission power for emitting a light beam.

The transmission power is adjustable as a function of the intensity of the reflected light beam. Furthermore, a gray-scale value of the measurement point is determined as a function of the transmission power adjusted.

An imaging unit outputs a video signal at a frame rate higher than a standard frame rate. During a zoom operation period or a period including the zoom operation period and periods before and after the zoom operation, a video signal from the imaging unit is recorded in a recording medium at a high recording frame rate. Other than this period, a video signal is recorded in the recording medium at the standard frame rate. The recording frame rate and zoom operation information is recorded as metadata in the recording medium. During reproduction, based on a set reproduction mode, thinning processing is carried out on a video signal recorded during a zoom operation, and the processed signal is output at the standard frame rate. In this way, it is possible to change a frame rate in view of a photographer's intention and assure compatibility with existing viewing and reproduction environments.
