Feature request: Multiply output with image for DSE correction #32

Open Simonxdd opened 1 year ago

Having the ability to multiply the image output with a user-specified image would make it possible to correct for Dirty Screen Effect (DSE) and improve screen uniformity.

I don't know if this is possible, but doing it through DWM would probably be the only way.

Actually, for a lower frequency pattern it would be more optimal to have multiple 3D luts for different regions of the display since it would be more accurate. It would be easier to create these 3d luts by just placing the colorimeter in the different regions. It would be way more time consuming for many display regions, but technically more accurate by having full color management.

For higher frequency stuff (like finer lines) it would be more optimal to take a picture of a grey slide, invert it and apply it to the display output with the correct blend mode to counter any brightness and color variations.

Idk if this is too niche to ever be implemented.
