Embodiment
In prior art, the application of shadow instrument projects to play content on arbitrary plane conventionally, but in a lot of situations, shows in the plane of project content and can have some chaff interferences.When carrying out projection setting at first, the specific region of avoid interference thing is selected in capital, but because in the process that projection is used, the position of possible chaff interference has some conversion, after the position of chaff interference changes, may there is the region of some projections preferably.But in existing shadow casting technique, if the position of chaff interference changes, occur that chaff interference and project content are overlapping, can only allow project content be presented on the outer surface of chaff interference, the view field of surface irregularity like this, can exist project content to show unclear problem.In addition, if it is relatively little to carry out at first the region of Projection Display, after chaff interference moves outlet than the region of current region projection preferably, according to the scheme of prior art, can only manually adjust the camera lens of projecting apparatus and the distance of view field change view field size and/thereby the position of adjusting camera lens of living adjusts view field, makes the view field of projector equipment adjust operation more loaded down with trivial details and be not easy to operation.
For the problems referred to above, the invention provides a kind of Projection Display picture adjustment methods, the method is applied in an electronic equipment, electronic equipment projects to displaying contents after the first plane, the method comprises: detect the chaff interference that whether has change in location within the scope of the setting regions of described the first plane, if had, the position after moving according to described chaff interference generates view field and adjusts order; Adjust order according to described view field and adjust the projected area of described displaying contents and/or the view field of displaying contents.
Method provided by the present invention, monitor in real time view field each object in the plane whether there is change in location, when change in location has occurred arbitrary object, may there is the plane domain of Projection Display preferably.So detecting that chaff interference position changes, the position after moving according to chaff interference is adjusted view field automatically.In method provided by the present invention, the position of chaff interference has occurred to change and has moved rear formed new region division by the movement and the chaff interference that detect chaff interference, area and the position of corresponding automatic adjustment view field, thereby thereby project content and the overlapping unsharp problem of displaying contents that causes of chaff interference are avoided, and electronic equipment determines that optimum carries out the region of projection automatically, thereby the loaded down with trivial details step of having avoided projection to adjust.In addition, the electronic equipment automatically area to regional and length and width calculates, and the projected image area of adjusting than the implementation of artificial adjustment projector lens is more reasonable, and has shortened the time that projection is adjusted.Below in conjunction with Figure of description, method provided by the present invention is further described:
As shown in Figure 1, the embodiment of the present invention provides a kind of Projection Display picture adjustment methods, below in conjunction with Figure of description, the specific embodiment of the present invention is elaborated:
The method is applied in an electronic equipment, this electronic equipment comprises projection arrangement, if because user wants to carry out projection in the little region of Area comparison, according to existing implementation, need adjustment projector lens repeatedly of user and the distance of view field, and repeatedly select just can find a suitable view field.So the method that the embodiment of the present invention provides, needs that will to carry out projection in a certain region all applicable after electronic equipment is projected to the first plane by displaying contents or detecting, the method comprises:
In this embodiment, described electronic equipment can be the device that can realize arbitrarily projection, in this embodiment for convenience of description, gives an example take described electronic equipment as projecting apparatus.
As shown in Figure 2, if projecting apparatus projects on desktop same displaying contents, because desktop can be placed with a lot of chaff interferences as shown in Figure 3 in concrete environment for use, when being placed with multiple cups on desktop.Chaff interference one, chaff interference two and chaff interference three as shown in Figure 3.User has been projected in displaying contents in the region of B, F, C and G composition according to demand.
When detecting that variation has occurred for chaff interference one and chaff interference three positions in Fig. 3, chaff interference moves the rear layout shown in Fig. 4 that formed.Electronic equipment is determined after the concrete layout after chaff interference position is adjusted, is generated view field according to the layout after adjusting and adjust order.
Chaff interference layout as shown in Figure 4 can be determined, after chaff interference position changes, can adjust the area of view field.The region of view field B, F, C and G composition from Fig. 3 is adjusted into the X region in Fig. 4.In this embodiment, because be extended to the more completely large region of a ratio after chaff interference adjustment on the basis of original view field, order so adjust described in this example the area that only need to adjust original viewing area.Corresponding view field adjusts the distance between corresponding controlling projection head and view field of order, thus make that displaying contents can be complete be presented at X region.
In concrete application, whether can detect interfering object by various ways such as image detection, ultrasound examination, infrared detection moves, in this embodiment take image detection as example, specifically detect within the scope of the setting regions of described plane and whether have the chaff interference of change in location to comprise:
