Abstract

The invention discloses a method and system for recognizing a target object from a background. The method comprises the steps that an image collecting unit is used for collecting a displayed image of a display unit so as to obtain first image information; the brightness of the image is adjusted; second image information of the display unit is obtained through the image collecting unit; the position, on the display unit, of the object is determined according to the first image information and the second image information. By the adoption of the method or system, interference to the object position determining process by the brightness of the display unit can be eliminated, and therefore the position of the object above the display unit can be determined accurately.

Description

technical field [0001] The invention relates to the field of object positioning, in particular to a method and system for identifying a target object from a background. Background technique [0002] With the continuous development of electronic devices, the ways of using the electronic devices are also becoming more and more diverse. In the prior art, there are new ways of using electronic equipment with a display unit. [0003] An electronic device with a display unit may be a tablet computer, a mobile phone, or other electronic devices with a screen. The tablet computer is taken as an example for description below. In the prior art, the tablet computer can be used as a board for games such as "Monopoly", and real dice are thrown on the screen of the tablet computer to play the game. During the game, a camera will be set above the display unit. The image collected by the camera is analyzed, and the image contains dice information. The process of analyzing the images co...
