Claim 5:
6. An implementation method for operating a night vision device with distance measurement function by use of component characteristic data as input data to calculate an estimated distance to a target object, comprising:
inputting a target object size, wherein size data of the target object are inputted through an operating unit and transmitted to a night vision and distance measurement system, and wherein a computing operation is done by the night vision and distance measurement system while the target object and an auxiliary mark are shown on a display;
displaying a preset distance, wherein the night vision and distance measurement system causes the auxiliary mark to show a size pattern corresponding to the size data and the preset distance;
correcting the preset distance, wherein, the preset distance is corrected through the operating unit, the size pattern shown by the auxiliary mark is adjusted by the night vision and distance measurement system based on the size data and the corrected preset distance; and
displaying an estimated distance, wherein, when the auxiliary mark and the target object have the same size pattern, the corrected preset distance is the estimated distance.
