Method and device for video enhancement, and electronic device using the same

A device for video enhancement, applied to an electronic device, comprising:

• a parameter obtaining unit, configured to obtain a current brightness of a display panel of the electronic device when a video is playing in the display panel;
• a parameter comparison unit, configured to compare the current brightness of the display panel with a target brightness;
• an effect determination unit, configured to determine an effect of video enhancement according to a comparing result of the parameter comparison unit;
• and
• a video enhancement unit, configured to process the video according to a video enhancement corresponding to the effect of video enhancement,
• wherein, before comparing the current brightness with the target brightness, the parameter obtaining unit is further configured to determine the target brightness according to a usage habit of a user, by:
• obtaining an expected brightness predetermined basing on an input instruction when the video is playing;
• storing the expected brightness associating with a light intensity of an environment in which the electronic device is currently located;
• and
• determining the target brightness that is corresponding to the light intensity to be a half of the expected brightness.

An electronic device, comprising one or more processors, a video codec, a memory;

• and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors;
• and when the one or more programs are executed the processor performs a method for video enhancement, which comprises:
• obtaining a current brightness of a display panel of the electronic device when a video is playing in the display panel;
• determining a target brightness according to a usage habit of a user, comprising:
• obtaining an expected brightness predetermined basing on an input instruction when the video is playing;
• storing the expected brightness associating with a light intensity of an environment in which the electronic device is currently located;
• and
• determining the target brightness that is corresponding to the light intensity to be a half of the expected brightness;
• comparing the current brightness with the target brightness;
• determining an effect of video enhancement according to a comparing result of the current brightness and the target brightness;
• and
• processing the video, by adjusting at least one parameters of images of the video, according to a video enhancement corresponding to the effect of video enhancement.
