Abstract
An interframe difference processorgenerates a difference image between frames of a sensor image, and an image processorgenerates distance information indicating a distance to a photographic subject on the basis of calculation of a difference image and a developing pattern. Thus, since a video display apparatusgenerates the difference image between the frames of the sensor image, it is possible to realize a distance measuring apparatus capable of reducing an influence of a background and generating distance information with high accuracy.
