SYSTEM FOR EXTRACTING HIDDEN IMAGE USING AXIALLY DISTRIBUTED IMAGE SENSING MODE, AND METHOD FOR EXTRACTING HIDDEN IMAGE THEREOF

摘要

The present invention relates to a system for extracting a hidden image using an auxiliary distributed image sensing (ADS) technique and a method thereof. The first aspect of the present invention provides the system for extracting the image which includes a camera (10), an image extracting device (20), and a camera driving device (30). The image extracting device (20) includes an ASD module (21) which moves the camera (10) by driving the camera driving device (30) in a z axis which is an optical axis and obtains a plurality of original images photographed by the ASD technique by the camera (10).
