Blurring a specific position of the computer screen

phùng hưng 1 Reputation point

I want to blur a position with a specified coordinate specified in its own way (x, x + h, y, y + w), but I don't know how to do this, it is related concerning the display driver and how to get frame by frame of the computer screen (as if reading frame by frame of video). Thank you everyone for watching.
