Disclosed are examples for adjusting screen brightness based on screen content being presented on a display screen of a mobile device. The described examples may determine a time at which the screen content is to be evaluated. The screen content is categorized based on the evaluation. A category of the screen content may be input into a machine learning algorithm that may be used to determine whether a screen brightness adjustment is appropriate. If a screen brightness adjustment is appropriate, a degree of the screen brightness adjustment may be determined.

A system, method, and computer-readable medium are disclosed for reducing halo artifacts of static images on a computer display. A multimedia stream is received that includes graphical images which are moving and static images as displayed on the computer display.
