METHOD AND APPARATUS FOR RAPID IMPROVEMENT OF SMOG/LOW-LIGHT-LEVEL IMAGE USING MAPPING TABLE

摘要

Disclosed are a method and apparatus for rapid improvement of a smog/low-light-level image using a mapping table. The method and apparatus provide a clear image by enhancing visibility fast with respect to a smog/low-light-level image, of which visibility is low due to impurities in the air. The apparatus includes: an inversion input unit; a lowest brightness image conversion unit; an atmospheric brightness value calculation unit; a transmission rate LUT calculation unit; a low-pass filter processing unit; a transmission rate allocation unit; a restored-image generation unit; and an inversion output unit. According to the present invention, the method and apparatus for rapid improvement of a smog/low-light-level image using the mapping table enable an embedded processor to operate in real time due to an extremely small amount of computation compared to the conventional technique.
