The image that S201, reception camera send, this image is that camera carries out image acquisition to camera viewing area and obtains, camera viewing area covers the area that the view field of projector and the area of camera viewing area are greater than view field, and this image comprises main process equipment display interface that view field projects and user and adopts dot pattern picture indicated by optical transmitting set.
Specifically, this S201 is camera 13 and gathers image and the process sending to main process equipment 11.Also be, main process equipment 11 can receive the image that camera sends, this image is that camera 13 pairs of viewing areas 15 carry out image acquisition and obtain, this image not only comprises main process equipment 11 display interface that view field 14 projects, and also comprises user and adopts dot pattern picture indicated by optical transmitting set 17.Unlike the prior art, the present embodiment does not limit user one and fixes on the enterprising line operate of view field 14, but can at the enterprising line operate of whole view field 15.
S202, according to this position of image determination luminous point in camera viewing area;
Specifically, after main process equipment 11 receives this image, adopt video image processing technology can know the position of luminous point in the viewing area 15 of camera 13 that user indicates.This position both may be arranged in view field 14, also may be arranged in first area 16.
It should be noted that, it will be appreciated by persons skilled in the art that above-mentioned video image processing technology can adopt existing arbitrary image treatment technology, the present embodiment does not limit.
S203, determine whether this position is arranged in first area, this first area is the region removed in camera viewing area outside view field;
If this position of S204 is arranged in first area, then adopt the operational order corresponding with first area, operation is carried out to the display interface of main process equipment and controls.
Specifically, main process equipment 11, after obtaining the position residing for luminous point, needs to determine whether this position is arranged in first area 16, if main process equipment 11 determines that the position of this luminous point is arranged in view field 14, then identical with operation control procedure of the prior art, the present embodiment does not repeat.The present embodiment can preset the operational order corresponding with this first area 16.If main process equipment 11 determines that this position is arranged in first area 16, then main process equipment 11 can adopt the display interface of operational order to main process equipment 11 of this first area 16 correspondence to control.
It is corresponding with this first area 16 that those skilled in the art can preset any operational order, thus make user once by light spot position instruction in first area 16, can perform the specific operation controlling functions corresponding with this first area 16.Be understandable that, the operational order corresponding from first area 16 can change in the setting different according to user.
For example, this operational order can comprise:
The instruction of picture amplifieroperation, the instruction of picture reduction operation, scrolling operations instruction, refresh operation instruction, rollback operation instruction, forward operation perform.
In the process of above-described embodiment specific implementation, main process equipment 11 both can determine corresponding operational order according to the positional information at luminous point place in first area 16, also can determine corresponding operational order according to the display state change information of luminous point in first area 16, corresponding operational order can also be determined according to the positional information at luminous point place in first area 16 and the display state change information of luminous point simultaneously.Wherein, the display state change information of this luminous point both can be the motion track information of this luminous point in first area 16, also can be the flashing times information of this luminous point in first area 16.
The concentrated specific implementation of determination operation instruction is provided below:
Mode one: according to the positional information at luminous point place in the first region, determines the subregion that luminous point is residing in the first region; According to the subregion at luminous point place, determine corresponding operational order.
Specifically, first area 16 is divided into multiple subregion by which one, and every sub regions all can a corresponding operational order.Main process equipment 11 can determine that luminous point is on the basis of first area 16, can also determine on which subregion of this light spot position in first area 16 further, thus can determine to adopt the operational order that this subregion is corresponding to carry out operation control to the display interface of main process equipment 11.
For example, first area 16 in Fig. 1 can be divided into top subregion, below subregion, left side subregion and the right subregion, its corresponding picture amplifieroperation instruction respectively, the instruction of picture reduction operation, upwards scrolling operations instruction, scrolling operations instruction downwards.Therefore, if main process equipment 11 determines the top subregion of luminous point in first area 16, then it can determine that the required operational order performed of user is the instruction of picture amplifieroperation, and therefore, main process equipment 11 can carry out picture amplifieroperation to its display interface; If main process equipment 11 determines the following subregion of luminous point in first area 16, then it can determine that the required operational order performed of user is the instruction of picture reduction operation, and therefore, main process equipment 11 can carry out picture reduction operation to its display interface; If main process equipment 11 determines the left side subregion of luminous point in first area 16, then it can determine that the required operational order performed of user is upwards scrolling operations instruction, and therefore, main process equipment 11 can control its display interface upwards roll screen; If main process equipment 11 determines the right subregion of luminous point in first area 16, then it can determine that the required operational order performed of user is downward scrolling operations instruction, and therefore, main process equipment 11 can control the downward roll screen of its display interface.
It should be noted that, in which one, the number of the subregion that first area is divided is more, operational order that then can be corresponding more, but the accuracy of user operation may decline to some extent, therefore, those skilled in the art rationally can arrange position and the number of subregion, thus can corresponding operational order as much as possible, the operating accuracy of user can not be reduced again.
Mode two: obtain luminous point motion track information in the first region; According to motion track information, determine luminous point direction of motion in the first region; According to the direction of motion of luminous point, determine corresponding operational order.
Specifically, which two determines corresponding operational order based on the direction of motion of luminous point.This mode requires user's mobile light spot position in first area 16.Main process equipment 11 can obtain the motion track information of luminous point in first area 16, thus this motion track information can determine luminous point direction of motion in the first region, and then according to this direction of motion, can determine corresponding operational order.
For example, if main process equipment 11 determines that the direction of motion of luminous point in first area 16 is for from bottom to top, then can determine that corresponding operational order is the operational order of main process equipment 11 display interface of rolling downwards; If main process equipment 11 determines that the direction of motion of luminous point in first area 16 is for from the top down, then can determine that corresponding operational order is the operational order of main process equipment 11 display interface of scrolling up; If main process equipment 11 determines that the direction of motion of luminous point in first area 16 is for from left to right, then can determine that corresponding operational order is the operational order of main process equipment 11 display interface of sliding left; If main process equipment 11 determines that the direction of motion of luminous point in first area 16 is for from right to left, then can determine that corresponding operational order is the operational order of main process equipment 11 display interface of sliding to the right; If main process equipment 11 determines that the direction of motion of luminous point in first area 16 is hoop, then can determine that corresponding operational order is the operational order refreshing main process equipment 11 display interface.
Mode three: determine luminous point flashing times in the first region in preset time range; According to the flashing times of luminous point, determine corresponding operational order.
Specifically, which three based on user control optical transmitting set 17 carry out on first area 16 luminous point flicker realize.Main process equipment 11 can determine that luminous point is in preset time range, such as, in 5s, and the flashing times in first area 11.Different flashing times, operational order that can be corresponding different, therefore, main process equipment 11 according to the flashing times of luminous point, can determine corresponding operational order.
Such as, main process equipment 11 determines that luminous point glimmers 2 times in 5s, then can determine that corresponding operational order is the instruction of picture amplifieroperation, if determine, in 5s, luminous point glimmers 1 time, then can determine that corresponding operational order is the instruction of picture reduction operation.
It should be noted that, those skilled in the art can sets itself time range as required, and it is long that this time range can not set, with the problem avoiding operating delay larger.
Mode four: according to the positional information at luminous point place in the first region, determines the subregion that luminous point is residing in the first region, and, according to the motion track information of luminous point in subregion, determine the direction of motion of luminous point in subregion; According to subregion and the direction of motion of luminous point in subregion at luminous point place, determine corresponding operational order.
Specifically, which four mode one and mode two is combined to realize.Which is by corresponding for a kind of direction of motion in a sub regions operational order.Main process equipment 11 can determine the subregion at luminous point place, and the direction of motion of luminous point can be determined according to the motion track information of luminous point in subregion, thus can according to the subregion at luminous point place and luminous point the direction of motion in subregion, determine corresponding operational order.
For example, if main process equipment 11 determines that the subregion at luminous point place is the top subregion in first area 16, and determine that the direction of motion of luminous point in this top subregion is from left to right, then can determine a kind of operational order, if main process equipment 11 determines that the subregion at luminous point place is the right subregion in first area 16, and determine that luminous point is hoop at this by the direction of motion in the subregion of limit, then can determine another kind of operational order.
Mode five: according to the positional information at luminous point place in the first region, determines the subregion that luminous point is residing in the first region, and, determine the flashing times of luminous point in preset time range in subregion; According to subregion and the flashing times of luminous point in subregion at luminous point place, determine corresponding operational order.
Specifically, which four mode one and mode three is combined to realize.Which is by corresponding for a kind of flashing times in a sub regions operational order.Main process equipment 11 can determine the subregion at luminous point place, and according to the flashing times of luminous point in preset time range in subregion, thus according to the subregion at luminous point place and flashing times, can determine corresponding operational order.
For example, if main process equipment 11 determines that the subregion at luminous point place is the top subregion in first area 16, and determine that luminous point glimmers 2 times in 5s in this top subregion, then can determine the first operational order, if main process equipment 11 determines that the subregion at luminous point place is the right subregion in first area 16, and determine that luminous point glimmers 4 times in 5s in this top subregion, then can determine another kind of operational order.
To be understandable that, the combination of subregion and direction of motion in mode four, or the combination of subregion and flashing times in mode five, to make first area 16 can corresponding more operational order.
