Please refer to the system block diagram that Fig. 1 is the portable electronic devices 10 applying crested image projection method of the present invention.Crested image projection method of the present invention is mainly used in portable electronic devices 10, such as the portable electronic devices etc. of intelligent mobile phone, flat computer, notebook computer or other support screen touch-control input functions, but the present invention is not as limit.
As shown in Figure 1, portable electronic devices 10 of the present invention comprises display module 11, picture detection module 12, picture acquisition module 13 and image projection module 14, and display module 11 and other each modules are electrically connected.In one embodiment of this invention, display module 11 can be touch-control display panel, and picture detection module 12, picture acquisition module 13 and image projection module 14 each can be perform the system tool of specific function, application program or hardware chip, but the present invention is not as limit, aforementioned each module also can be the two above combination arbitrarily in hardware, software and firmware.
In addition, portable electronic devices 10 of the present invention also comprises processing unit and storage element (not shown), processing unit (such as CPU (central processing unit)) sends instruction to perform the operating system or application program that are stored in storage element (such as internal memory or hard disk), and shows corresponding display frame by display module 11; This display frame can be the system interface of operating system or the program interface of application program.In one embodiment of this invention, operating system can be the windows system (such as windows8) of Microsoft, but the present invention is not as limit.Because aforementioned processing unit and storage element are the inner common necessary assembly of electronic installation, do not add to repeat at this.
Picture detection module 12 in order to judge the input cursor in display frame position whether cover by the input area (such as dummy keyboard or blank handwriting area) opened.Picture detection module 12 can the real-time status of detection display picture, confirms the position of input cursor at present, and after input area is opened, judges to input cursor whether be transfused to region and cover.In one embodiment of this invention, picture detection module 12 can according to the coordinate parameters of location of pixels each in display frame, the respective coordinates in region occupied by the position and the input area that obtain input cursor mutual comparison, so as to judging whether the input area opened covered the position of input cursor, but the present invention is not as limit.
Picture acquisition module 13 can according to the testing result of picture detection module 12, determines to carry out picture acquisition around the position whether for input cursor.When input the position of cursor be transfused to region cover time, picture acquisition module 13, namely input the position of cursor for reference point, captures the regional area picture around the position inputting cursor.In other words, captured in the present invention regional area picture must comprise the position of input cursor.
And in order to keep the position inputting cursor to move to outside regional area picture because user continues input characters, picture acquisition module 13 can change along with the position of input cursor, the regional area picture that real time acquisition is new, the position of the input cursor after changing with correspondence; That is, regional area picture moves along with the position inputting cursor and changes, and makes the position of input cursor continue the same position place remained in regional area picture.
Image projection module 14 is used to Projection Display regional area picture in display frame.The regional area picture that image projection module 14 can capture according to picture acquisition module 13, upgrades the regional area picture of institute's Projection Display, reflects image content corresponding at present in real time to change in response to text event detection situation.
Please refer to the process flow diagram that Fig. 2 is crested image projection method of the present invention.It is noted that, though below coordinate the portable electronic devices 10 shown in Fig. 1 for example illustrates crested image projection method of the present invention, but the present invention is not as limit, any portable electronic devices with similar framework or function all can apply crested image projection method of the present invention.As shown in Figure 2, crested image projection method of the present invention comprises step S1 to step S4.Each step of the method will be described in detail below.
Step S1: open input area in display frame.
When user to click in the system interface of display frame or Application Program Interface can a certain position (such as data folder or filename block, text-only file content part or arbitrary text event detection block) of input characters time, an input cursor can be shown in this position, confirm the position of current text event detection with assisted user; Now system judges that user has the demand of text event detection, therefore can automatically open and show input area in display frame, so that user utilizes this input area to perform text event detection operation.
Step S2: judge whether the position of the input cursor in display frame is transfused to region and covers.
After input area is opened, picture detection module 12 can judge whether input area covered the position of input cursor.If judge, the position of input cursor has been transfused to region and has covered, then continue to perform step S3; If the position of input cursor is not transfused to regions shield, then display frame keeps current state, and continues to perform step S2 to detect the relative position between the position of input cursor and input area in real time.
Below please also refer to Fig. 3 A and Fig. 3 B.Fig. 3 A is the schematic diagram representing primary importance P1 and second place P2 in display frame A; Fig. 3 B is the schematic diagram that the primary importance P1 that the present invention is directed in Fig. 3 A performs when clicking input.As shown in Figure 3A, suppose that shown by current display frame A, person is a file management interface; When user wants to revise the title of each file data folder in interface, only need to click corresponding file data folder position, aforementioned input cursor can be occurred, modify for user's amendment.Below for the primary importance P1 in Fig. 3 A and second place P2, carry out aid illustration method of the present invention.
As shown in Fig. 1, Fig. 3 A and Fig. 3 B, when the primary importance P1 that user clicks in Fig. 3 A presss from both sides the title of Music to revise file data, picture detection module 12 judges that input area K does not cover the position of the input cursor O that residence occurs, represents that the position of input cursor O is directly shown on display frame A; Now user can watch current text event detection state, and picture detection module 12 can continue to detect display frame A.
Step S3: the regional area picture around the position of acquisition input cursor.
If the position of the input cursor judged in display frame in abovementioned steps S2 is transfused to regions shield, now picture acquisition module 13 to input the position of cursor for reference point, can capture the regional area picture around the position inputting cursor in display frame.In one embodiment of this invention, picture acquisition module 13 is the positions inputting cursor is a picture center, and then the regional area picture (such as a rectangle block scope) in an acquisition setting range, but the present invention is not as limit, the position such as inputting cursor also can be picture proximal edges position.
Step S4: project regional area picture in display frame.
Image projection module 14 can by picture acquisition module 13 in abovementioned steps S3 the regional area picture around the position of input cursor that captures, Projection Display, in display frame, watches the text event detection state of the position of contiguous input cursor at present for user.
Below please also refer to Fig. 4 A and Fig. 4 B.Fig. 4 A is the schematic diagram that the second place P2 that the present invention is directed in Fig. 3 A performs when clicking input.Fig. 4 B is the schematic diagram that the position of input cursor O changes regional area picture A1 after movement.
As shown in Fig. 1, Fig. 3 A and Fig. 4 A, in one embodiment of this invention, when the second place P2 that user clicks in Fig. 3 A presss from both sides the title of Data03 to revise file data, position due to occurred input cursor O has been transfused to region K and has covered, picture acquisition module 13 can capture the regional area picture A1 around the position of input cursor O, and via image projection module 14 Projection Display in display frame A.Image projection module 14 can produce a Projection Display block B herein, in order to show this regional area picture; And Projection Display block B can be presented in the residual picture region R of display frame A except input area K (being such as positioned at the top of input area K), to avoid Projection Display block B to cover input area K, hinder the input operation of user.And the position inputting cursor O is the picture center being positioned at regional area picture A1.
And for example shown in Fig. 1 and Fig. 4 B, when moving when inputting cursor O and performing the process of text event detection along with user (such as increase or delete word content), picture acquisition module 13 can capture new regional area picture thereupon, and is shown in Projection Display block B via image projection module 14.Therefore, regional area picture A1 can move along with the position of input cursor O and change, and makes the position inputting cursor O remain at the picture center of regional area picture A1.
In addition, crested image projection method of the present invention also comprises step S5: close regional area picture.
When picture detection module 12 judges that the position of input cursor is no longer transfused to regions shield (such as user change the position of input cursor or input cursor shifted out input area institute range of defilade outer), represent that user directly can see the position of input cursor in display frame, therefore picture detection module 12 can notify that image projection module 14 closes regional area picture.In addition, when user terminates input action, regional area picture also can be closed thereupon.For example, when after closedown input area, input cursor can not be transfused to regions shield naturally, and therefore image projection module 14 along with the closedown of input area, can close regional area picture in the lump; In addition once after the text event detection of user operated (such as pressing input validation key), the input cursor in display frame can disappear, and now regional area picture also can be closed automatically.
Please refer to the process flow diagram that Fig. 5 is another embodiment of crested image projection method of the present invention.As shown in Figure 5, in the present embodiment, the step S4 of crested image projection method of the present invention also comprises step S41 to step S43.Each newly-increased step of the method will be described in detail below.
Step S41: judge the residual picture region whether existed in display frame beyond input area.
Because regional area picture needs to be projected in display frame, and regional area picture will be avoided covering input area as far as possible, if input area occupies whole display frame or screen resolution is too small, may cause regional area picture cannot Projection Display smoothly.Therefore, after step S3 has captured regional area picture, picture detection module 12 can first detect the display frame of opening input area, judges the residual picture region whether existed in display frame except input area, for this regional area picture of Projection Display.
Step S42: judge whether residual picture region has enough projector spaces.
If there is the residual picture region beyond input area in display frame, then picture detection module 12 then can judge whether this residual picture region has enough projector spaces.Projection Display due to regional area picture is in order to assisted user watches the situation of current text event detection, if the regional area picture that projects out too small, easily cause the inconvenience of user on the contrary.Therefore, judge whether residual picture region has enough projector spaces by picture detection module 12, to determine this regional area picture that whether projects.Enough projector spaces described herein adjust according to setting difference.
For example, for Fig. 4 A, residual picture region R needs the Projection Display block B in the complete display Fig. 4 A of energy, just can be identified to have aforementioned enough projector spaces; If residual picture region R is less than the size of Projection Display block B, then assert that residual picture region R does not possess enough projector spaces.
Step S43: the suitable projected position in selection residual picture region is with the regional area picture that projects.
After having enough projector spaces in confirmation residual picture region, picture detection module 12 can notify image projection module 14, makes image projection module 14 can select a suitable projected position in residual picture region, with the regional area picture that projects.For example, for Fig. 4 A, watch this regional area picture for the convenience of the user, the display position of Projection Display block B should be positioned at the nearly middle position of display frame as far as possible, but the present invention is not as limit.
By design of the present invention, even if user is when performing text event detection operation, the position of input cursor is subject to input area and covers, still by inputting the regional area image projection of the position of cursor, learn the situation of current text event detection, the text event detection operation of user can not be affected, to provide text event detection effect more easily because of the unlatching of input area.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to appending claims of the present invention.
