Fig. 1 shows the schematic flow sheet of the display state of the control terminal screen that the embodiment of the present invention one provides, and as shown in Figure 1, the process of the display state of this control terminal screen, mainly comprises the steps:

The image of the display object of step 101, acquisition terminal screen, and determine the position of target setting in image.

In this step 101, when the image obtained comprises multiple display object, occupy the position of target setting in image corresponding to the maximum display object of image area in the multiple display object comprised by image, be defined as the position of target setting in image.Occupy the maximum display object of image area and usually can be defined as the nearest object of distance terminal screen, by this processing mode, using the main display object of object nearest for distance terminal screen as terminal screen, and in this, as determining the foundation of terminal screen display state, the accuracy of determination result can be improved.

Step 102, position according to target setting, determine the parameter of token image relative position on a terminal screen.

In this step 102, determine the parameter of token image relative position on a terminal screen, namely determine the angle of facial image and the terminal screen obtained.Wherein, target setting can be determined flexibly according to the type of image, the target of mark action can be played as target setting to image in main selection image, such as, for facial image, the eyes, nose, face etc. of face can play mark action to this face, therefore, that can select in these targets is one or more as target setting, to determine the parameter of token image relative position on a terminal screen.

Step 103, the corresponding relation of display state according to the parameter area preserved and screen, determine the display state of the screen corresponding with the parameter in-scope of token image relative position on a terminal screen.

In this step 103, the corresponding relation of the display state of parameter area and screen can be pre-configured, under normal circumstances, the target setting selected is different, the parameter for token image relative position on a terminal screen then determined also may be different, therefore, the corresponding relation of the display state of this parameter area and screen can configure with reference to selected target setting, and can be configured to many groups.

The display state control terminal screen of the screen that step 104, basis are determined.

In this step 104, according to the display state control terminal screen of the screen determined, namely control terminal screen is in the display state of determined screen, particularly, when determining to obtain image, whether the display state of the screen of terminal screen is consistent with the display state of the screen determined, if inconsistent, then the display state controlling this terminal screen switches to the screen display state determined, if consistent, then the display state controlling this terminal screen is constant.

So far, the flow process of the display state of control terminal screen terminates.
