S1, when cursor is positioned at the broadcast window P of player and translation functions key and is activated, follow the trail of the track of cursor in broadcast window P;
S2, at broadcast window P when video window O in the broadcast window P overlaps, and when the video window O in the broadcast window P showed the partial video image of intercepting on original video figure, the partial video image that video window O is shown was followed the track of cursor and translation.
Overlap with video window O in the broadcast window P at broadcast window P, and when the video image that video window O shows is partial video image on the raw video image, this moment is because the not change of the size of broadcast window P and video window O, but the area of the upper video image that shows of video window O has diminished relatively before, so being the video image that video window O shows, the visual effect that the video image that shows on the video window O brings to the user has been exaggerated than original image, so can realize by the way of playing the partial video image on the raw video image at video window O the amplification to the video image of video window O broadcast, like this, use the user of technique scheme provided by the present invention, in the situation of the frame size constancy of the video window O in broadcast window P, after the raw video image that shows in the video window O with broadcast window P (referring to not through amplifying also the not video image through dwindling) amplifies, when wanting the video image of demonstration in the translation broadcast window P, (for example: pin Ctrl can activate first the translation functions key, pin simultaneously left mouse button), then, the video image that shows in the mode translation broadcast window P by the translation cursor, thereby the video image that the video window O in the broadcast window P does not show is moved to video window O to be shown, compared with prior art, when watching the video image that does not show in the video window O under the state that amplifies among the present invention, need not to reduce first video after amplifying, also need not again to pull out again a rectangular area, more convenient so operate, and then solved prior art and have function singleness, the technical matters of troublesome poeration.
When the translation functions key was activated in the present embodiment, its trigger pip of sending can be used as the translation instruction, and for example: can be triggered when namely being activated Ctrl and left mouse button, the trigger pip of sending is as the translation instruction.Because the position of cursor is to be controlled by mouse, when arranging like this, clicks by left mouse button, just can confirm the video image that shows in the video window O is carried out translation.Certainly, in the time of also right mouse button and/or other buttons can being triggered in the present embodiment, the trigger pip of sending is as the translation instruction.
Can use following provided by the present inventionly overlap with video window O in the broadcast window P at the broadcast window P of player as shown in Figure 2 in the present embodiment, and show the method for taking from the partial video image on the raw video image in the situation of the frame size constancy of video window O, the video image that shows in the video window O is amplified demonstration, then, after the video image amplification that shows in the video window O, re-use the partial video image that shows in the said method translation video window O provided by the present invention, also can use the method that provides in the prior art with after the video image amplification that shows in the video window O, re-use the video image after amplifying in the said method translation video window O provided by the present invention.
The video image that the translation video window shows after being dwindled by raw video image:
Method of video image processing in the present embodiment, further comprising the steps of:
When the video window O that shows raw video image is less than or equal to broadcast window P, make video window O with and the video image of interior demonstration all follow track translation under the constraint of broadcast window P of cursor.
The video window O that shows raw video image is less than or equal to two kinds of situations of broadcast window P existence, the one, it is broadcast window P and video window O overlaid that video window O equals broadcast window P, the one, broadcast window P is greater than video window O, at this moment, video window O with and the video image of interior demonstration all reduced with same ratio, so translation this moment video image need to be with video image and in the lump translation of video window O, but, because the video image that this moment, video window O showed is raw video image, the video image that video window O shows is whole pixel regions corresponding to raw video image at pixel region corresponding to raw video image.
In the present embodiment video window O with and the track translation under the constraint of broadcast window P of all following cursor of the video image of interior demonstration comprise that the Geometric center coordinates of the long limit of video window O and long limit that broadside is no more than broadcast window P and broadside or video window O is limited in the broadcast window P or the track of cursor is limited in the broadcast window P.
This design so that the user when translation video window O, can video window O thoroughly not shifted out broadcast window P because of maloperation, thereby affect normally watching of video image.
In the present embodiment, the track of cursor is the track of cursor translation in video window O, make in this method of video image processing video window O with and the video image of interior demonstration all follow the method for track translation under the constraint of broadcast window of cursor, may further comprise the steps:
According to the corresponding relation between the coordinate of the track of the coordinate of video window O before the translation in broadcast window P, cursor and predefined track and video window O, calculate the coordinate of translation rear video window O in broadcast window P, and with the position translation of video window O to the corresponding position of the coordinate that calculates;
The pixel data that the extract real-time raw video image is corresponding, and in video window O, play out corresponding video image according to pixel data.
The track of cursor can be the track of cursor translation in video window O, also can be the track of the regional translation of cursor between video window O and broadcast window P, is preferably the track of translation in video window O.Corresponding relation between the coordinate of track and video window O is in advance artificial setting, and be preferably: the coordinate Complete Synchronization of track and video window O, like this, in the translation process, the coordinate of video window O is relative static with cursor each other.
In the present embodiment method of video image processing, make the video image that shows in the video window O follow the track of cursor and the method for translation may further comprise the steps:
The mapping point of pixel region on pixel region corresponding to raw video image corresponding to partial video image that video window O is shown followed the track of cursor and changed;
Pixel data corresponding to pixel region that extract real-time is limited by the mapping point after changing, and in video window O, play out with mapping point according to pixel data and to follow the trail of accordingly video image.
Because video window O display part video image, so video image is in magnifying state, simultaneously, because video window O overlaps each other with broadcast window P and is relative static, so can by the partial video image that shows in the mode translation broadcast window P of translation cursor, show thereby the video image that the video window O in the broadcast window P does not show is moved to video window O.
The raw video image that shows in the amplified video window O:
Shown in 1a among Fig. 1 and 1c part, in the present embodiment at broadcast window P when video window O in the broadcast window P overlaps, make the method for the interior partial video image of video window O demonstration raw video image in the broadcast window P, may further comprise the steps:
S01, receive the trigger pip by the peripheral hardware input, and determine enlargement factor according to trigger pip, enlargement factor is amplified the multiple that shows for the video image that will show in the video window O;
S02, calculate the mapping point of pixel region in pixel region corresponding to raw video image corresponding to partial video image that the video image after the amplification shows according to enlargement factor in video window O;
Pixel data corresponding to pixel region that S03, extract real-time mapping point limit, and in video window O, play out corresponding partial video image according to pixel data.
The present invention can be by peripheral hardware (for example: the roller of roll mouse and/or the left button of clicking the mouse, right button, roller, pressing keys) mode, in the situation of the frame size constancy of input broadcast window P and video window O, the video image that shows in the video window O is amplified the multiple that shows, and then can amplify demonstration to the video image that shows in the video window O according to enlargement factor, need not to adopt the method for prior art in video window O, to pull out a rectangular area, as seen, the present invention not only inputs enlargement factor can be more accurate, and operation is also more convenient.
Dwindle that video window O shows by the partial video image on the raw video image:
Shown in 1c among Fig. 1 and 1e part, in the present embodiment, this method of video image processing, further comprising the steps of:
S04, receive the trigger pip of peripheral hardware input, and determine minification according to trigger pip, minification is for dwindling the video image that shows in the video window O multiple of demonstration;
S05, video window O show be the partial video image time, calculate the mapping point of pixel region in pixel region A corresponding to raw video image corresponding to partial video image that the video image after dwindling according to minification shows in video window O;
Pixel data corresponding to pixel region that S06, extract real-time mapping point limit, and in video window O, play out corresponding partial video image according to pixel data.
Among the present invention when video window O show be the partial video image time, when being pixel region R corresponding to the partial video image that shows of video window O less than pixel region A corresponding to raw video image, be described this moment, the partial video image that video window O shows still is in the state of amplification, for example: after 10 times of raw video image amplifications, dwindle again 2 times, at this moment, the partial video image that video window O shows still is in and amplifies 5 times state, so the pixel region E of the part correspondence that the video image after dwindling shows at video window O is still less than pixel region A corresponding to raw video image.
Because the partial video image that the present invention shows in can also realizing in the situation of the frame size constancy of video window O video window O dwindles demonstration, so that the user is when using player to watch video image, can in the situation of the frame size constancy of video window O, arbitrarily amplify, dwindle the partial video image that shows in the video window O, for example: in amplification process, the multiple that amplifies is too large, can also will dwindle again through the video image that amplifies, thereby the video image amplification effect that obtains wanting, so use more convenient.
Dwindle the raw video image that video window O shows:
Shown in 1a among Fig. 1 and 1b part, method of video image processing in the present embodiment, further comprising the steps of:
Reception is by the trigger pip of peripheral hardware input, and determines minification according to trigger pip, and minification is for all dwindling the video image that shows in video window O and the video window O multiple of demonstration with same ratio;
When pixel region corresponding to video image that shows at video window O is pixel region corresponding to raw video image, dwindle video window O according to minification, determine video window O contracted position coordinate;
The step of contracted position coordinate is: being that the height of minification and current video window O is long-pending with the reduced height of video window O frame, is the amassing of width of minification and current video window O with the reduced width of video window O;
The pixel data that the extract real-time raw video image is corresponding, and in the video window O that dwindles, play out corresponding video image according to pixel data.
When pixel region R corresponding to video image that shows at video window O is pixel region A corresponding to raw video image, the shown video image of video window O is raw video image, at this moment, raw video image is dwindled demonstration, namely dwindle the raw video image that video window O shows, at this moment, the frame size that only need to dwindle video window O, need not to change pixel region corresponding to video image that shows at video window O, for example minification is 1/2 o'clock, 1/2 before the frame of video window O is of a size of and dwindles.At this moment, minification m can be set to 1/k, k is greater than 1, when being set as backward (or downwards) scroll wheel, inductor produces a trigger pip, k increases 1 or 0.1, the value that is minification diminishes, can think the video image after dwindling is dwindled demonstration again this moment, and during (or upwards) scroll wheel, inductor produces a trigger pip forward, it is the value increase of minification that k reduces 1 or 0.1, when the value of k was reduced to 1, when continuing forward (or upwards) scroll wheel, inductor produced a trigger pip, then be considered as enlargement factor n and increase to 2 or 1.1 from 1, if when continuing forward (or upwards) scroll wheel, inductor produces a trigger pip, then enlargement factor n increases 1 or 0.1.
Shown in 1b among Fig. 1 and 1f part, method of video image processing in the present embodiment, further comprising the steps of:
Reception is by the trigger pip of peripheral hardware input, and determine enlargement factor according to trigger pip, enlargement factor is in the situation of the frame size constancy of broadcast window P, and the video image that shows in video window O and the video window O is all amplified the multiple that shows with same ratio;
Pixel region corresponding to video image that shows at video window O is pixel region corresponding to raw video image and video window O during less than broadcast window P, according to enlargement factor amplified video window O, determines that video window O amplifies position coordinates; The step of amplifying position coordinates is: the height of video window O frame is enlarged into enlargement factor long-pending with the height of current video window S shown in 1f part among Fig. 1, the width of video window O is enlarged into the amassing of width of enlargement factor and current video window S;
The pixel data that the extract real-time raw video image is corresponding, and in the video window that amplifies, play out corresponding video image according to pixel data.
The current video window refers to the video window of the last time before zooming in or out, and for example: amplify if want that video window is carried out the 5th, then then for after the 4th amplifies, the 5th is amplified video window before to the current video window.
When the pixel region corresponding to video image that can show at video window O according to said method be pixel region corresponding to raw video image, the video window O after will dwindling and all again amplify with the video image that same ratio dwindles with video window O.
In the present embodiment, this method of video image processing, further comprising the steps of:
When video window O less than broadcast window P or part when shifting out broadcast window P, Fill Color between video window O and broadcast window P;
And/or, when the border of video image O moves into video window P, Fill Color between the border of video window O and video image.
The color of filling is preferably ColorKey look (Transparent color) or black, also can fill other colors outside the black such as blueness, green, certainly, dwindle in the present embodiment and also can make broadcast window P in the process of video window O along with video window O and dwindling of video image and scaled down.
As shown in Figure 1, in the present embodiment, the method for the mapping point of pixel region in pixel region A corresponding to raw video image that the partial video image that calculating shows in broadcast window is corresponding may further comprise the steps:
S0201, judge whether cursor is positioned at video window O;
S0202, when cursor is positioned at video window O, pixel with cursor in the pixel region pointed or that point to the geometric center place of video window O is as the constant point in position, calculate the mapping point of pixel region R in pixel region A corresponding to raw video image corresponding to partial video image that in video window O, shows according in the video image after the enlargement factor amplification, perhaps
Pixel in the pixel region that points to the geometric center place of video window O is as the constant point in position, calculates the mapping point of pixel region in pixel region A corresponding to raw video image corresponding to partial video image that the video image after dwindling according to minification shows in video window O.
In the present embodiment when cursor is positioned at video window O, be preferably with the pixel in the cursor pixel region pointed as the constant point in position, calculate the mapping point of pixel region R in pixel region A corresponding to raw video image corresponding to partial video image that video window O shows, because the position of cursor can artificially be controlled by the user, so the user can control mapping point in pixel region R corresponding to video image that the shown needs of video window O amplify by the position of control cursor, and then can zoom in or out more freely the position of the shown partial video image of video window O, be conducive to improve user's experience.
No matter whether cursor is positioned at video window O in the present embodiment, be preferably geometric center with video window O as the constant point in position, calculate the mapping point of pixel region in pixel region A corresponding to raw video image corresponding to partial video image that the video image after dwindling according to minification shows at video window O, because the geometric center of video window O is the point that location comparison is easily determined, so point to pixel in the pixel region as the constant point in position with the geometric center place of video window O, the partial video image that video image after calculating is dwindled shows in video window O is when the mapping point of pixel region corresponding on the raw video image in pixel region A corresponding to raw video image, calculating operation can be more easy, and counting yield can be higher.
The below more describes for example among the present invention the amplification that specifically how to operate to realize to the video image of playing in the video window in detail, dwindles and translation:
The process of amplifying:
During video playback, pin Ctrl, when mouse pointer (cursor) was positioned on the picture (video image that video window is shown), pointer became the magnifier shape.When unclamping Ctrl, mouse pointer recovers acquiescence and namely is reduced to magnifier shape shape before.
When mouse pointer is positioned on the picture, pin Ctrl, rotate the middle button of mouse roller forward, mouse becomes the magnifier shape with plus sige, picture is pressed the length breadth ratio geometric ratio of Set For Current and is amplified, in the process of amplifying, it is constant that the point at mouse pointer place is kept its relative position in whole video window.Mouse whenever sends a signal, and the picture length and width respectively multiply by 1.1 (this enlargement factor can artificially be set).When picture after 60 times (this number of times can artificially be set) amplified on the basis of original size, even rotate mouse roller forward, image also no longer amplifies, and mouse pointer is shown as magnifier (not being with plus sige) shape again.
The process of dwindling:
When mouse pointer is positioned on the picture, pin Ctrl, rotate the middle button of mouse roller backward, mouse becomes the magnifier shape with minus sign, picture is by current length breadth ratio Scaling, in the process of dwindling, if picture is also large than window, then to keep its relative position in whole video window constant for the point at mouse pointer place; If picture narrows down to less than window, then picture is placed in the middle.Mouse whenever sends a signal, and the picture length and width are respectively divided by 1.1 (or respectively multiply by 1/1.1).When picture after the basis of original size dwindles 24 times (this number of times can artificially be set), even rotate mouse roller backward, image also no longer dwindles again, and mouse pointer is shown as magnifier (not being with minus sign) shape.
If picture rotates, overturns, then the picture after rotation, upset is done the picture zoom operations.
Picture is exaggerated or when dwindling, shows in picture upper right corner information display area: " pin Ctrl, double-click the picture reduction ".Herein, reduction instigates video window to be back to the state that shows raw video image;
The picture convergent-divergent is only to playing effectively when inferior.
The process of translation:
During video playback, pin Ctrl, when mouse pointer was positioned on the picture, pointer became the magnifier shape.When unclamping Ctrl, mouse pointer recovers acquiescence.
Pin Ctrl, when mouse pointer is positioned on the picture, pin left mouse button, pointer becomes hand shape, drags mouse, and picture is translation thereupon.Pixel of mouse translation, then also pixel of translation of picture.Unclamp left mouse button, pointer recovers the magnifier shape.
If picture rotates, overturns, zooms in or out, then the picture after rotating, overturning, zoom in or out is done the pan operation.
Picture shows in picture upper right corner information display area during by translation: " pin Ctrl, double-click the picture reduction ".
Pan is only to playing effectively when inferior.
Below more detailed elaboration realizes the employed algorithm of above-mentioned functions of the present invention, and following algorithm is part preferred implementation provided by the present invention only, and the present invention can also realize with other algorithms outside the following algorithm:
In the present embodiment, the pixel region A that video window O and raw video image are corresponding is all rectangular, and both are preferably similar figures;
The method of the mapping point in the pixel region A of pixel region R correspondence on raw video image that the partial video image that the video image after calculating is amplified according to enlargement factor shows in video window O is corresponding may further comprise the steps:
S021, with one of them summit of video window O as the window initial point, determine that cursor is with respect to the coordinate figure of window initial point;
S022, with one of them summit of pixel region corresponding to the video image before amplifying as the temporary transient initial point of pixel, according to the height of the frame of video window O, width respectively with amplify before the height, the proportionate relationship between the width of pixel region corresponding to video image, determine that the position of the pixel in the cursor pixel region pointed is with respect to the coordinate figure of the temporary transient initial point of pixel;
S023, with one of them summit of raw video image as pixel benchmark initial point, determine that the temporary transient initial point of pixel is with respect to the coordinate figure of pixel benchmark initial point, and according to the coordinate figure of the temporary transient initial point of pixel with respect to pixel benchmark initial point, enlargement factor, the height of video window O, the position of the pixel in width and the cursor pixel region pointed is with respect to the coordinate figure of the temporary transient initial point of pixel, the height of the pixel region that the video image that shows at video window O before amplifying is corresponding, width calculates at least two nonadjacent vertices of pixel region R corresponding to partial video image that the video image after amplifying according to enlargement factor shows at video window O with respect to the coordinate figure of pixel benchmark initial point.
The pixel region A that video window O and raw video image are corresponding is similar figures, and both are when all rectangular, raw video image can be on video window O the complete video image that demonstrates.Certainly, video window O and raw video image can not be similar figures also, like this, video window O can play out the partial video image on the raw video image, perhaps, when video window O play raw video image, video window O did not show that the part of image can fill black.
Any one summit of video window O all can be used as the window initial point, any one summit of the pixel region A that raw video image is corresponding is as the temporary transient initial point of pixel, the coordinate figure of any two nonadjacent vertices all can be determined position and the size of a rectangle, in the present embodiment, be preferably the point in the use video window O upper left corner as the window initial point, use the point in the upper left corner of pixel region A corresponding to raw video image as the temporary transient initial point of pixel, use the coordinate of the upper left angle point of pixel region R of the part correspondence that the video image after amplifying according to enlargement factor shows in video window O and bottom right angle point to determine the position of pixel region R in pixel region A corresponding to raw video image corresponding to video image through amplification.Because point, the bottom right angle point in the upper left corner are than the point that is easier to determine, identify, so help the workload that reduces to calculate.
More elaborate the how video image in the amplified video window O of the present invention below in conjunction with Fig. 2.

That dwindles video window O demonstration has passed through the video image that amplifies by raw video image:
More elaborate the present invention below in conjunction with 1c among Fig. 1 and 1e part and Fig. 3 and how to dwindle in the video window O the video image through amplifying.
As shown in Figure 3, identical among the implication of region representation shown in A, the E and Fig. 1 among the figure, region representation shown in the D dwindles the partial video image that shows in the video window when showing, before dwindling, and pixel region corresponding to partial video image that shows in the video window; The coordinate of benchmark initial point is (0,0).
In the present embodiment, pixel region R corresponding to the partial video image that shows at video window O is during less than pixel region A corresponding to raw video image, calculate the method for the mapping point of pixel region in pixel region A corresponding to raw video image corresponding to the partial video image that in video window O, shows, be specially:
According to formula XBo=Xo-(1-m) * (X1-Xo) * Xo/[Wo-(X1-Xo)],
YBo＝Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)]，
XB1＝X1+(1-m)*(X1-Xo)-X1*Xo/[Wo-(X1-Xo)]，
YB1=Y1+ (1-m) * (Y1-Yo)-Y1*Yo/[Ho-(Y1-Yo)] calculate respectively in pixel region A corresponding to raw video image, the summit in the pixel region upper left corner that the partial video image that shows in video window O is corresponding and the summit in the lower right corner are with respect to the coordinate figure of pixel benchmark initial point; Wherein:
M is minification, 1＞m＞0, and (1/m)≤n;
XBo, YBo respectively are in pixel region A corresponding to raw video image, and the summit in the pixel region upper left corner that the partial video image that the video image after dwindling according to minification shows in video window O is corresponding is with respect to the horizontal ordinate of pixel benchmark initial point, the coordinate figure of ordinate;
XB1, YB1 respectively are in pixel region A corresponding to raw video image, and the summit in the pixel region lower right corner that the partial video image that the video image after dwindling according to minification shows in video window O is corresponding is with respect to the horizontal ordinate of pixel benchmark initial point, the coordinate figure of ordinate;
Wo, Ho respectively are the width of pixel region A corresponding to raw video image, highly.
As shown in Figure 3, owing to wanting multidisplay pixel to be in X-direction after dwindling: x1=(1-m) * (X1-Xo);
Want multidisplay pixel to be in Y direction after dwindling: y1=(1-m) * (Y1-Yo);
Therefore dwindling rear point (Xo, Yo) should translation on x axle negative direction, the distance of translation is:
FBx＝x1*Xo/[Wo-(X1-Xo)]；
So, XBo=Xo-x1*Xo/[Wo-(X1-Xo)]
＝Xo-(1-m)*(X1-Xo)*Xo/[Wo-(X1-Xo)]；
In like manner: dwindling rear point (Xo, Yo) should translation on the Y-axis negative direction, and the distance of translation is:
FBy＝y1*Yo/[Ho-(Y1-Yo)]；
So, YBo=Yo-y1*Yo[Ho-(Y1-Yo)];
＝Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)]；
Dwindle rear point (X1, Y1) should be on x axle positive dirction translation x1-FBx;
Therefore dwindle the point (XB1, YB1) in the rear lower right corner be
XB1＝X1+x1-FBx；
＝X1+(1-m)*(X1-Xo)-x1*Xo/[Wo-(X1-Xo)]；
Dwindle rear point (X1, Y1) should be on the Y-axis positive dirction translation y1-FBy;
YB1＝Y1+y1-FBy；
＝Y1+(1-m)*(Y1-Yo)-y1*Yo/[Ho-(Y1-Yo)]；
When partial video image shown in the video window O is dwindled demonstration, minification m is greater than 0, less than 1, and (1/m)≤n, at this moment, owing to being to dwindle through the video image that amplifies, so although video image has dwindled, but the effect that shown video image brings the user in the video window O for the video image that does not amplify still is the state that video image is in amplification, for example will amplify 6 times video image, be reduced into and amplify 2 times video image, at this moment, although video image has dwindled 3 times, but, amplify 2 times video image, for the video image that does not amplify, still be in and amplify 2 times state, so the interior shown partial video image of video window O still only is the partial video image on raw video image.
In the time of can realizing accurately the invariant position of the pixel in cursor pixel region pointed by the above coordinate figure that calculates, the partial video image that shows in the video window O is dwindled demonstration.
Because the sense organ of user's naked eyes usually can be too inaccurate, so above coordinate figure is to allow suitable error, even can carry out suitable change by above coordinate figure.Certainly, also can determine above-mentioned coordinate figure with the additive method outside the above method, for example: can set other relatively more suitable coordinate figures according to use experience.

The zoom function key can artificially be set, and zoom function key and translation functions key also can be same button.For example, zoom function key and translation functions key all can be set as Ctrl.
When the zoom function key is pressed, mode by scroll wheel just can be inputted enlargement factor or minification, for example: in wanting the amplified video window during shown partial video image, can be set as when (or making progress) rolls a roller forward, inductor produces a trigger pip, enlargement factor increases by 0.1, for example enlargement factor increases to 1.1 by 1, video image is exaggerated 1.1 times, the initial value that is to say enlargement factor and minification can be defaulted as 1, in the time of can being set as in the given time forward (or upwards) scroll wheel, inductor produces a trigger pip, enlargement factor n becomes n+0.1 or enlargement factor n are become n by n (for example 1.1) square (for example 1.21) by n (for example 1), backward during (or downwards) scroll wheel, inductor produces a trigger pip, enlargement factor n becomes n-0.1 by square root (for example 1.1) or the enlargement factor n that n (for example 1.21) becomes n by n, until n is 1 o'clock, if when continuing backward in the given time (or downwards) scroll wheel this moment, inductor produces a trigger pip, minification becomes 1-0.1 namely 0.9 or minification becomes 1/ (k+1) by 1/k or be 1/ (k+0.1) by the initial value 1 of minification, k is 1, if when continuing backward (or downwards) scroll wheel, inductor produces a trigger pip, minification continue to reduce 0.1 or k continue to increase by 0.1.The rule of correspondence between the number of times of the trigger pip that inductor sends, rotating direction and enlargement factor or the minification is Set arbitrarily artificially.
Certainly, in the present embodiment pressing keys can use press+or-number (for example: by once+enlargement factor adds 1 or 0.1) or the mode of directly inputting concrete numerical value input enlargement factor or minification.
