177 results about "Splash screen" patented technology

A splash screen is a graphical control element consisting of a window containing an image, a logo, and the current version of the software. A splash screen usually appears while a game or program is launching. A splash page is an introduction page on a website. A splash screen may cover the entire screen or web page; or may simply be a rectangle near the center of the screen or page. The splash screens of operating systems and some applications that expect to be run in full screen usually cover the entire screen.

System and method for adjusting brightness automatically

The invention provides a method for adjusting brightness automatically. The method comprises the following steps of: entering a first brightness sampling period, and acquiring a first average brightness value of a display screen during the first brightness sampling period; entering a second brightness sampling period, and acquiring a second average brightness value of the display screen during the second brightness sampling period; performing pre-brightness automatic adjustment operation; entering (2+N)th brightness sampling period, and acquiring the (2+N)th average brightness value of the display screen during the (2+N)th brightness sampling period; entering (3+N)th brightness sampling period, and acquiring the (3+N)th average brightness value of the display screen during the (3+N)th brightness sampling period, wherein N refers to the cycle index from 1; and performing post-brightness automatic adjustment operation, returning back to the step 5, and performing cyclic operation. By utilizing the method and the system, the set of brightness of the display screen can be held accurately under the condition that the external environment changes fast, and the splash screen phenomenon of a mobile terminal during the fast bright-dark switching of the external environment is avoided.
