Embodiment
The present invention proposes a kind of method that image scaling shows that realizes, and is applied to comprise the mobile device of touch-screen and Gravity accelerometer, if Fig. 1 is the method process flow diagram, comprising:
Step 101: detect the upset of mobile device, obtain the angle [alpha] that mobile device overturns centered by X-axis and the angle beta overturning centered by Y-axis; Wherein said X-axis is on screen, to pass through the straight line of a certain position, and Y-axis is the straight line vertical with X-axis.
Step 102: dwindle or amplify the image on touch-screen according to described α and/or β, and showing in viewing area.
If user wants the screen position of the mobile device controlled to touch, can adopt longly by the mode of touch-screen, to send and dwindle or amplify idsplay order, touch-screen obtains the input position of this instruction, and this input position is set to initial point.Or, user can adopt the mode of pressing specific keys to send to dwindle or amplify idsplay order, the point that can set in advance is in this case set to initial point, considers the finger needing near user, and certain point of screen that closes on so button can be used as initial point.Straight line parallel with touch-screen upper and lower side frame and by initial point is set to X-axis, and straight line parallel with touch-screen left and right side frame and by initial point is set to Y-axis.
In addition, can function be set middle increase is set, such as all or part of, open or closing function, such as the function of dwindling or amplifying.When opening reduction capability, with the head of a household, by touch-screen or while pressing specific keys, send and dwindle idsplay order; When opening enlarging function, with the head of a household, by touch-screen or while pressing specific keys, send amplification idsplay order.
When user sends while dwindling idsplay order, the method that mobile device adopts the present invention to propose, can by user's finger according to point centered by point, the angle of overturning of take is parameter, and whole screen display is mapped to near the region this central point.It is parameter that the area size of mapping be take the angle of upset, and the region that angle is larger, the flip angle of take is Parameter Mapping of upset is just less, reaches the object that user can be touched want the region controlled.Particularly, when downscaled images, above-mentioned steps 102 can be: the length X of image is converted into X * cos β; Or, the width Y of image is converted into Y * cos α.
For fear of image, show too small and affect operation, can arrange two groups for the max-thresholds of flip angle, being designated as coordinate and shining upon corresponding flip angle threshold alpha max1and β max1and corresponding flip angle threshold alpha is shone upon in viewing area max2and β max2, α wherein max2> α max1, β max2> β max1.When the flip angle of mobile device is less than α max1and β max1time, along with the increase of flip angle, image is more and more less, and viewing area is also more and more less, and viewing area can show whole image simultaneously; When flip angle meets and exceeds α max1and β max1time, along with the increase of flip angle, image no longer dwindles, and viewing area is still more and more less, and now viewing area can not show whole image simultaneously, need to increase in viewing area scroll bar and reach and control object; When flip angle meets and exceeds α max2and β max2time, image and viewing area all no longer dwindle.It should be noted that, flip angle α and β are without synchronous variation.
Concrete, above-mentioned steps 102 can comprise:
As β < β max1time, the horizontal ordinate X0 of pixel is converted into X0 * cos β, the lateral length P of viewing area is reduced into P * cos β, show the pixel after transforming;
Or, as α < α max1time, the ordinate Y0 of pixel is converted into Y0 * cos α, the longitudinal length Q of viewing area is reduced into Q * cos α, show the pixel after transforming;
Or, work as β max1≤ β < β max2time, the horizontal ordinate X0 of pixel is converted into X0 * cos β max1, the lateral length P of viewing area is reduced into P * cos β, in viewing area, horizontal scroll bar is set, show the pixel after transforming;
Or, work as α max1≤ α < α max2time, the ordinate Y0 of pixel is converted into Y0 * cos α max1, the longitudinal length Q of viewing area is reduced into Q * cos α, longitudinal scroll bar is set in viewing area, show the pixel after transforming;
Or, as β>=β max2time, the horizontal ordinate X0 of pixel is converted into X0 * cos β max1, the lateral length P of viewing area is reduced into P * cos β max2, in viewing area, horizontal scroll bar is set, show the pixel after transforming;
Or, as α>=α max2time, the ordinate Y0 of pixel is converted into Y0 * cos α max1, the longitudinal length Q of viewing area is reduced into Q * cos α max2, longitudinal scroll bar is set in viewing area, show the pixel after transforming.
Referring to accompanying drawing, lift specific embodiment the present invention is described in detail.
In the present embodiment, mobile device centered by X-axis towards user side to upset α, simultaneously centered by Y-axis towards the user β that overturns; For ease of showing, diagram comes the movement decomposition of the upset centered by X-axis and Y-axis to be described.
