DEVICE AND METHOD FOR INVERSE TONE MAPPING USING A SINGLE LOW DYNAMIC RANGE IMAGE, RECORDING MEDIUM FOR PERFORMING THE METHOD

摘要

The present invention is an apparatus and method for optimizing an inverse tone mapping based on a single image implemented to reconstruct a high quality HDR (High Dynamic Range) image using a low dynamic range (LDR) image, for performing the above method A recording medium, comprising: inputting a low dynamic range (LDR) image into an inverse tone mapping (ITM) operator; Inputting a result value by the ITM operator into a TM (Tone Mapping) operator; Comparing the result value by the TM operator with a threshold for reading HDR luminance; And selecting a result value by a TM operator smaller than a threshold as a high dynamic range (HDR) image.
