STRUCTURE OF A CAMCORDER FOR TRACKING A PHOTOGRAPHING POSITION IN A 3D SPACE THROUGH THE PHOTOGRAPHY OF A FIXED OBJECT WITH A SUB LENS

摘要

PURPOSE: A structure of a camcorder for tracking of a photographing position in a 3D space is provided to easily compose a real image and CG(Computer Graphics). CONSTITUTION: A main lens(110) takes a photograph of a real image. A sub lens(120) takes a photograph of a sub image for a fixed object. In order that the main lens and the sub lens are synchronized, a synchronizing signal generator(130) offers a reference signal. An image output unit(160) outputs a main image or the sub image to the outside or outputs the stored main image or sub image of each storage unit(140,150) to the outside.
