An HDR Image Encoding Method Compatible with LDR Image Format
Because of its excellent performance,the High Dynamic Range(HDR)display becomes more and more popular in many fields.The problem is that most of the display devices available nowadays are still for Low Dynamic Range(LDR)content only.As a result,finding a way to achieve the compatibility between LDR content and HDR content is necessary.In this paper,we provide an improved version of the JPEG-HDR model which allows typical drivers to read and display a tone-mapped image while the HDR information is carried in “sub-band marker.On the other hand,we can recover the HDR image with the help of inverse tonemapping operator(iTMO)and “sub-band marker.It is the backwards-compatible enhancement to HDR.When an application is not designed for HDR imaging,it displays only the tone-mapped image,allowing the user to have access to part of the content.When an application is designed for HDR imaging,we can recover the original HDR image by decoding process.
