Method for video enhancement and computer device using the method

A computer device, comprising:

• a video capture module, retrieving an input image;
• a determination module, determining whether a full enhancement mode or a fast enhancement mode is implemented to the input image by the following steps, wherein the full enhancement mode processes all pixels of the input image, and the fast enhancement mode processes varied pixels of the input image:
• setting a period parameter;
• determining whether a count value for a counter is greater than or equal to the period parameter;
• when the count value is less than the period parameter, switching to the fast enhancement mode and accumulating the counter;
• and
• when the count value is not less than the period parameter, switching to the full enhancement mode and resetting the counter;
• and
• a calculation module, when the fast enhancement mode is determined to be implemented, implementing motion detection for the input image, in which enhancement coefficients of varied pixels of the input image are recalculated and updating the enhancement coefficients to an enhancement coefficient table;
• and
• an adjustment module, adjusting pixel colors of the input image based on the enhancement coefficient table and outputting the adjusted image.
