Abstract: A measurement apparatus obtains a reference signal from reference light modulated at a first frequency and a measurement signal from measurement light reflected by a target object modulated at a second frequency along with movement of the target object in addition to the modulation at the first frequency, and processes the reference signal and the measurement signal to measure a position of the target object. Synchronized detection units multiply the measurement signal by a signal synchronized with the reference signal and output signals having the second frequency and harmonic components. Decimation filters filter, at a decimation frequency, the signals output from the synchronized detection units to attenuate the harmonic components.

Abstract: A medium storing a program for display control. When the program is executed by a computer realized in a mobile terminal, the mobile terminal operates as follows. An area-information storing unit stores information on a first display area of an external display device and a second display area of a built-in display. A screen-data production unit acquires content to be displayed, and produces screen data corresponding to the first display area. An entire-image display unit divides the screen data into partial areas each corresponding to the second display area, adds to the entire screen data area-display data indicating the extent of each partial area and a corresponding identifier, and displays the screen data on the external display device. On receipt of an identifier, a partial-image display unit extracts a portion of the screen data for a partial area corresponding to the identifier, and displays the portion on the built-in display.
