MOBILE TERMINAL DEVICE, DISPLAY CONTROL METHOD AND PROGRAM

摘要

The purpose of the present invention is to acquire the position of a viewer without increasing the cost of a TV set including a TV housing and a remote controller and increasing restrictions on design due to a distance sensor and a camera provided therefor, and to allow for the adjustment of image quality of an image displayed on the display device on the basis of the acquired position of the viewer. A mobile terminal device (2) includes an imaging unit, a display unit, and a transmission unit. The imaging unit can capture an image of at least a portion of a display screen of the display device. The display unit can display an image captured by the imaging unit. When a calculation image (T) required for calculating the distance from the display screen to the mobile terminal device is included in the captured image, the transmission unit transmits, to the display device, adjustment information for adjusting the image quality of the display screen on the basis of the distance (L) calculated using the captured image.
