After that, the user interface 202 is used to provide a plurality of intersecting virtual lines 101a-101e, so as to divide the original image 100 into a plurality of image regions 102 (as shown in step S11 in FIG. 1 ).

Please refer to FIG. 3A to FIG. 3C . FIG. 3A is a schematic diagram of an original image 100 according to an embodiment of the present description. FIG. 3B to FIG. 3C are schematic diagrams illustrating an operation screen for performing image adjustment on the original image 100 in FIG. 3A according to an embodiment of the present description. In some embodiments of this specification, the original image 100 may be a polygonal image (such as (but not limited to) a rectangle, a triangle with regular or irregular side lengths, a quadrilateral, a pentagon, etc.), a circle Shaped images, elliptical images, or images with curved edges or other shapes.

In this embodiment, the original image 100 is a rectangular image with a plurality of original image edges 103a-103d. These image areas 102 include a plurality of edge areas 102E1-102E10 and a plurality of central areas 102C1 and 102C2. Each edge region (one of the edge regions 102E1-102E10) is composed of at least one original image edge (one of the original image edge 103a-103d) and at least two virtual lines (one of the virtual lines 101a-101e) of the original image 100. ) as defined. Taking the edge area 102E1 as an example, the edge area 102E1 is a grid area defined by two original image edge lines 103a and 103d and two virtual lines 101a and 101d of the original image 100 .

Next, change the coordinates of at least one intersection point (for example, intersection point 104a) between at least one virtual line (for example, virtual line 101b) and the original image edgeline (for example, original image edgeline 103a), to obtain a deformed image edgeline 105a (such as shown in step S12 of Fig. 1).

FIG. 4A to FIG. 4B are schematic diagrams illustrating partial curve conversion steps of converting the deformed polyline 105b' into a continuous and smooth deformed image edge 105b according to an embodiment of the present specification. For the convenience of description, Fig. 4A to Fig. 4B only show the transformation of a part of the deformed fold line 105a' (for example, the straight line segment between the end point 104c and the intersection point 104a' shown in Fig. 3B) into a curve ( For example, the steps of the curved line segment between the end point 104c and the intersection point 104a' shown in FIG. 3C).

The line segment P1P0 connecting the virtual point P0 and the endpoint 104c is divided into 3 equal parts with the nodes D1 and D2, so that the line segment P1D1=line segment D1D2=line segment D2P0; and the line segment connecting the virtual point P0 and the intersection point 104a' is divided into nodes D3 and D4 P2P0 is divided into 3 equal parts, so that line segment P2D4=line segment D4D3=line segment D3P0. Connect nodes D1 and D3 and connect D2 and D4 respectively so that line segments D1 D3 and D2 D4 intersect. Then divide the line segment D1 D3 into 3 equal parts with nodes S1 and S2, so that line segment D1S1=line segment S1S2=line segment D3S2. Divide line segment D2 D4 into 3 equal parts with nodes S3 and S4, make line segment D2S3=line segment S3S4=line segment D4S4.

Select a node on both sides of the intersection of line segment D1 D3 and line segment D2 D4 as a relay point. For example, in this embodiment, the intersection of the line segment D1 D3 and the line segment D2 D4 is exactly the coincident node S2/S3. The nodes on both sides of the line segment D1 D3 and the line segment D2 D4 located at the intersection S2/S3 are nodes S1 and S4 respectively. Connect the end point 104c (P1), the intersection point 104a' (P2) and the two relay points (nodes S1 and S4), and you can get a broken line composed of the three line segments of the first segment P1S1, S1S4 and S4P2 (as in Section 4B as shown in the figure).

Next, calculate with the interpolation method, according to the relative relationship between the original image edge 103a and the two intersection points 109 and 108b of the virtual line 101d and the straight line 107, and the original pixel 106, calculate when the original image edge 103a is transformed into the deformed image edge 105a , another imaginary line 101f passing through the original pixel 106 and parallel to the original image edge 103a (refer to Figure 3A), after being adjusted in the same direction as the deformed image edge 105a and converted into a curve 101f', the intersection point 106' with the straight line 107 The coordinates (X0, Y3). Wherein, the intersection point 106' is the position after the repositioning of the original pixel 106 (refer to step S13a in FIG. 1 ). same When using similar steps, each other original pixel (not shown) in the edge regions 102E1-102E10 in the original image 100 is repositioned to obtain the deformed image 110 shown in FIG. 3C.

It is worth noting that, in the step of obtaining the deformed image edge 105a, the step S12b described in FIG. 1: converting the deformed polyline 105a' into a continuous and smooth deformed image edge 105a is not a necessary step. Therefore, in some other embodiments of this specification, the deformed image edge line obtained in step S12b described in FIG. 1 is omitted, and may be a continuous polyline connecting the two endpoints of the original image edge lines 104b and 104c and the intersection point 104a' ( That is, the deformed fold line 105a'). In other words, the deformed image (not shown) obtained by omitting the step S12b described in FIG. 1 may be a polygonal image.
