Changing every pixel color value on the screen

Question

Hi Support Team,

We need to make color adjustments on the fly.
For example, increasing/decreasing blue by 1 on every pixel of the LCD screen

There are many images on the screen, so it wouldn't be efficient to make a change individually.
Do you have any good idea for this topic?

Best Regards,
Kangmin

Hello Kangmin,

the overall pixel color adjustment will be not a very performant approach. But you can do that by modifying the framebuffer content directly after Embedded Wizard has completed the update. For that purpose let me refer to the article Framebuffer Dump Data.

Alternatively: In case you want to make some color adjustment, maybe your display controller provides some gamma correction.

Best regards,

Manfred.
