Touch signal, and the coordinate contained by the touch signal determines the corresponding coordinate of the handwriting trace currently inputted.
It is practical when determining the corresponding coordinate of the handwriting trace currently inputted, different sides can be used according to actual scene demand
Formula is exemplified below several ways：
Mode one：In order to quickly judge that the position of handwriting trace, can be directly to write rail whether in predetermined edge area
The starting of mark writes the coordinate of point to judge.Determine the seat that the starting of the handwriting trace currently inputted is write to point when coordinate
It is denoted as the corresponding coordinate of the handwriting trace currently inputted.
Mode two:Under certain scenes, it is contemplated that the writing style of user, usually according to from left to right or from up to down
Sequence stroke writing only can write point with the termination of handwriting trace and judge, determining will currently input when coordinate by described
The coordinate of point is write in the termination of handwriting trace, as the corresponding coordinate of the handwriting trace currently inputted.
Mode three:In order to avoid in user according to being done from dextrad or bottom-up sequence stroke writing, only to terminate book
It writes and is a little judged, it may occur however that erroneous judgement can be write point and be terminated with the starting of handwriting trace and write point to judge, determine coordinate
When the starting of the handwriting trace currently inputted write into point, and terminate and write the coordinate of point and currently inputted as described
The corresponding coordinate of handwriting trace.
Mode four：In view of the shape of the handwriting trace of input may be irregular, only write point with starting and terminate and write
Point is judged, it may occur however that erroneous judgement, so when determining coordinate, it can be by all books of the handwriting trace currently inputted
Coordinate a little is write, as the corresponding coordinate of the handwriting trace currently inputted.
Mode four：Under certain scenes, stylus or user's finger press write it is lasting to the process that stops writing is lifted
Time may be long, and the writing point contained by the handwriting trace of input is more, if with all writing points contained by handwriting trace
Being judged, the time of consuming may be relatively more, in order to improve efficiency while taking into account accuracy, the embodiment of the present invention,
It, can be by the boundary coordinate of the minimum outsourcing rectangular area of the handwriting trace currently inputted, as described when determining coordinate
The corresponding coordinate of handwriting trace currently inputted.When judgement, only with the maximum of the coordinate range of boundary coordinate and minimum into
Row judges.
The embodiment of the present invention can determine the corresponding seat of the handwriting trace currently inputted by any of the above mode
Mark, can also determine coordinate by other means, can also obtain institute by the other modes except coordinate contained by touch signal
The coordinate of the handwriting trace currently inputted is stated, the embodiment of the present invention is without limitation.
Such as in certain application scenarios, the related image capture device of terminal device, such as camera is installed in terminal and sets
Near standby, it is used for the touch screen of camera terminal equipment, when finger or Pointer contacts write region, the screen picture of shooting also can
Including the image data of finger or stylus, the embodiment of the present invention can obtain the writing currently inputted by following operation
The position of track：
Each frame screen picture write described in associated image capture device and transmitted after operation is detected is received, and is passed through
Object in the every frame screen picture of identification for triggering handwriting trace, determines the corresponding seat of the handwriting trace currently inputted
Mark, wherein the object is stylus or user's finger.
For the coordinate determined, judging the position whether when writing the predetermined edge area in region, it can be determined that
Whether identified coordinate is in the coordinate range in the predetermined edge area, if can be determined that and described currently inputting
The position of handwriting trace is in scheduled marginal zone.
In other examples, when whether judging the position in the predetermined edge area in writing region, it can also judge institute
Whether determining coordinate is in the coordinate range of target area, if it was not then can be determined that the writing rail currently inputted
The position of mark is in scheduled marginal zone.Wherein, the target area refer in the writing region except the predetermined edge area it
Outer region can specifically see Fig. 2 B and Fig. 2 C.
It is specific when judging, if the corresponding coordinate of the handwriting trace currently inputted have it is multiple, as long as any coordinate exists
In the coordinate range in predetermined edge area, or not in the coordinate range of target area, the book currently inputted can be judged
The position of track is write in scheduled marginal zone.
If it is coordinate in a coordinate range that it is coordinate that the handwriting trace currently inputted is corresponding, as long as the coordinate
Range and the coordinate range in predetermined edge area have intersection, alternatively, the coordinate range is not fully contained in the coordinate model of target area
In enclosing, it can judge the position of the handwriting trace currently inputted in scheduled marginal zone.
When the embodiment of the present invention judges that the position of the handwriting trace currently inputted is in scheduled marginal zone, show to touch
Control pen or the finger of user have been approached the edge for writing region, in order to avoid because of page turning, wiping in the operations such as the track inputted
The writing of disconnected user, can be adjusted the handwriting trace of input.And under different application scenarios, the handwriting trace that is adjusted and
Predetermined adjustable strategies will be different based on adjustment, or even the opportunity of adjustment would also vary from, and be exemplified below several answer
Use scene：
