Abstract
The invention provides an automatic color matching method in a video playing interface. The method comprises a first step of acquiring video image data displayed on a current video playing window through a video decoding interface; a second step of converting the acquired video image data into red, green and blue (RGB) data, and performing located capture on RGB video image data in a background video image overlapping region of a control state information icon and a video playing window and a peripheral visual range through a display position of a control information display icon; a third step of quantifying the captured RGB video image data to obtain an average value, so as to obtain RGB values of a color having obvious difference from the color of the captured background video image overlapping region; and a fourth step of using the color with the RGB values newly obtained as the displaying color of the control information display icon. The invention also provides an automatic color matching system in the video playing interface. The system can dynamically display the displaying color of the control state information icon, so that the icon displayed in a foreground is obviously different from the video image displayed in the background. The system is easy to use and operate by users.
