During solving existing projection process, user can not leave computer directly to the Projection Display of projector Picture carries out the problem of operation control, and the embodiment of the present invention proposes a kind of projection process method.

Fig. 1 is projection process embodiment of the method flow chart of the present invention.

Referring to Fig.1, the projection process method that the embodiment of the present invention proposes, specifically includes the following steps:

S11, the user object run area to be operated is determined, wherein the object run area is located in view field, described View field is the region of original projection data image.

It should be noted that the object run area in the present embodiment is targeted when being user's progress gesture or motion action , and the region being located in view field.Initial data image is the data image of initial projections.

In practical applications, initial data image is projected to corresponding view field, when user is led in view field When a certain region carries out gesture or movement, determines that the region is object run area, further realize so as to subsequent to object run The operation in area identifies.

S12, the operation according to the user in the object run area generate corresponding mark image, and the mark is schemed Target image is generated as merging with the initial data image.

Wherein, mark image is the figure for the image data shown in object run area to be differently shown or identified Picture.Target image is to operate the obtained image with corresponding display effect in object run area according to user, with specific reference to The corresponding mark image of operation of the user in object run area merges to obtain with initial data image.

It should be noted that the mark image in the present embodiment is the operation generation according to the user in object run area 's.In a specific embodiment, one picture is performed to the image data in object run area in object run area such as user The operation of underscore then generates a corresponding straight line image as mark image according to the operation, and by the rectilinear of generation The image for carrying straight line image is generated as merging with initial data image, obtains target image.

S13, Xiang Suoshu view field project the target image;Wherein, the target image is located at the view field Interior, the mark image is located in the object run area.

In practical applications, after generating target image, by the target image generated to view field's projection, to realize Display picture after view field shows user's operation, specifically, target image is located at the projected area in projection process In domain, mark image is located in object run area, to guarantee that mark image accurately for showing with the region of operation, obtains Corresponding control effect, and then realize the flexible control to projection display picture.

Projection process method provided in an embodiment of the present invention, by determine the user object run area to be operated, according to Operation of the family in object run area generates corresponding mark image, and the mark image of generation is merged life with initial data image It is projected at target image, and by the target image of generation to view field, with the display after view field shows user's operation Picture realizes the flexible control to projection display picture, enhances the experience of user.

In an alternate embodiment of the present invention where, the determination user mesh to be operated in the step S11 of above-described embodiment Operating space is marked, as shown in Fig. 2, further including steps of

If S111, detecting that infrared detection line is blocked by obstructions in the view field, the shelter is obtained The currently coordinate value in the view field.

Wherein, the infrared detection line in the present embodiment is that the infra-red ray detection device being arranged in above the view field hangs down The directly a plurality of infrared ray for being parallel to the view field that emits downwards, the entire projected area of a plurality of infrared radiation Domain.

Specifically, infra-red ray detection device can be infrared word laser emitter, infrared word laser emitter is downward It shines, forms one layer of infrared smooth surface parallel with view field in front of view field.

In practical applications, what can be emitted by real-time detection infra-red ray detection device is parallel to the more of the view field Infrared ray, with the presence or absence of part is blocked by obstructions, realizes the detection in object run area, when there are quilts in the view field When a plurality of infrared ray that shelter blocks, then according to shelter, movement routine forms multiple coordinate values in the view field, To determine the user object run area to be operated.

S112, the coordinate value obtained according to step S111, determine the user object run area to be operated.

Wherein, multiple coordinate values are shelter mobile corresponding multiple seats of continuous path formed in the view field Scale value.Specifically, the path identified according to the multiple coordinate value corresponding region in view field is object run Area.The embodiment of the present invention accurately and reliably realizes the identification in object run area by using the mode of infrared induction, and Implementation is simple.
