摘要： A display device prevents the display screen from flickering even when the display mode changes automatically. The display device has plural modes, a viewing environment detector that detects the ambient brightness and changes the mode based on the detected ambient brightness, a screen brightness calculator that calculates the brightness of the display screen in each mode based on the average brightness of video data in one frame, and a screen brightness merger that, when the mode changes, gradually changes the brightness of the display screen from the brightness of the display screen before the mode change to the brightness of the display screen after the mode change.

摘要： Conventionally, there has been a danger that CCD saturation may occur because of the influence of the shot noise and the environment light if a higher resolution of a distance image showing the distance to an object present in a target space and a higher frame rate are achieved when the distance image is estimated by the TOF method, and the distance accuracy may degrade. An emission frequency selecting unit (7) receives light (S2) reflected from the object when a light source does not emit light and selects illumination light (S1) having an emission frequency insusceptible to the environment light according to the frequency analysis of the reflected light (S2). An image creating unit (6) selects a light source emitting the illumination light having the optimum emission frequency from among prepared light sources (9A to 9N), receives reflected light of the illumination light from the selected light source, and creates the distance image showing the distance to the object. The environment light can be mitigated during light reception, and the noise influence on the distance accuracy can be mitigated when a light-receiving element unit (2) exhibiting higher resolution is used.
