To synchronize the measurement frequency by a distance sensor and the imaging frequency by a camera, if necessary.SOLUTION: An information processor includes: image acquisition means for acquiring a camera image from a camera which images a real object; distance acquisition means for acquiring a distance up to the real object by measurement of a distance sensor; and control means in which, when synchronization of the imaging frequency by the camera and the measurement frequency of the distance sensor is required, the imaging frequency by the camera and the measurement frequency of the distance sensor are synchronized by changing a measurement range of the distance sensor.SELECTED DRAWING: Figure 2
