Conversion between HDR and SDR can be performed either on a “live” signal, using a hardware/software signal processor, or in post-production using editing or colour correction (grading) software. This conversion may be done mathematically, using an algorithm which takes the numerical values of each image pixel and calculates new values, based either on preset functions, or functions with user controls to modify the conversion.
The ORION-CONVERT algorithm takes a novel three step approach to HDR <> SDR conversion, with a simple and intuitive set of user controls.
Because the ORION-CONVERT is mathematically defined, it is mathematically invertible.
