Pre-display adaptive codeword mapping for display monitor with non-ideal electro-optical transfer function

A system, comprising:

• a display monitor compatible with a video specification having a reference electro-optical transfer function (EOTF) while exhibiting an actual EOTF that deviates from a reference EOFT;
• and
• a video source subsystem configured to:
• determine an approximated EOTF representative of the actual EOTF based on user input received from a display of at least one test pattern to a user via the display monitor, the at least one test pattern to elicit input from the user based on a visual inspection of the at least one test pattern by the user;
• convert color values of each video image of a stream of video images to corresponding non-linear codewords based on the approximated EOTF;
• and
• transmit the codewords to the display monitor for display as display images representative of the video images.

A method, comprising:

• providing, from a processing system, a graphical user interface (GUI) for display to a user via a display monitor, the GUI including presentation of a set of one or more test patterns;
• receiving, at the processing system, user input based on a visual inspection of the one or more test patterns by the user;
• determining, at the processing system, an approximated electro-optical transfer function (EOTF) based on the user input, the approximated EOTF representative of an actual EOTF exhibited by the display monitor;
• and
• for each video image of a stream of video images:
• converting, at the processing system, color values of the video image to corresponding codewords based on the approximated EOTF;
• and
• providing the codewords for transmission from the processing system to the display monitor.
