Next, referring to FIG. 1, in step S103, it is determined that one of the inputs of the continuous pattern 204 is a non-closed area input. That is, when the continuous graphic 204 does not surround the image 202 displayed by the display 200, but an arc-shaped gesture graphic is formed on the display 200, it is determined that the input of the continuous graphic is a non-closed area input. The curved gesture graphic is, for example, a semi-circular arc. In the step of determining that the input is a non-closed area input, first, a minimum outer boundary of the continuous graphic 204 is determined according to the relative coordinates of the starting point 204a, the ending point 204b of the continuous graphic 204 and the graphic connecting point 204c on the display 200 (steps) S105). 3A to 3B and FIGS. 3A' and 3B', when the continuous graphic 204 is directly input on the display 200, the start point 204a, the end point 204b of the continuous graphic and all the graphic connection points 204c are respectively given on the display 200. Relative to a landmark of display 200, a minimum boundary 306 (shown in Figure 3A') is defined based on all coordinates on continuous pattern 204, this minimum outer boundary enclosing a minimum image area including continuous graphics 204/304 308. The shape of the minimum outer boundary 306 is, for example, a rectangle.

The sub-region 308a further includes at least one central sub-region 308b located at a geometric center point of the image region 308. In the embodiment of Figs. 3A' and 3B', an example of dividing the image area surrounded by the minimum outer boundary into three-by-three is divided. However, the present invention is not limited to the above-described division of the image area into three-by-three aliquots. That is, the image area enclosed by the minimum outer boundary can be equally distinguished according to the developer's own definition.

Next, in step S109, a first sub-region and a second sub-region where the start point 204a and the end point 204b are respectively located, and a plurality of third sub-regions where the partial graphic connection point 204c near the end point 204b are located are determined. Following the step S111, it is determined that the input of the continuous pattern 204 is a non-closed area input. Referring to FIG. 3A and FIG. 3A′, the start point 304a of the continuous pattern 304 is located in the first sub-area IA, and the end point 304b is located in the second sub-area IIIC, and the graphic connection point 304c near the end point 304b is located in the third time. In the regions IIIC and IIIB, the first region IA, the second region IIIC, and the third region IIIC, IIIB are not adjacent to each other, and it is determined that the input of the continuous pattern is the non-closed region input.

In addition, in an embodiment, referring to FIG. 3B and FIG. 3B′, determining the input condition that the input of the continuous graphic is a non-closed region further includes: when the secondary region 308a of the graphic connecting point is distributed, the center is not included. In the area 308b, it is determined that this input is a non-closed area input.

Referring to FIG. 1 and FIG. 2B, after step S103, step S113 is performed to perform an image rotation operation of the image 202 on the display 200. In step S113, performing an image rotation operation further includes: in step S115, determining a pattern forming direction 210 of the continuous pattern 204 from the starting point 204a through the graphic joint point 204c to the end point 204b, that is, the net direction formed by the continuous pattern. 4 is a schematic diagram showing a pattern forming direction of a continuous pattern according to an embodiment of the present invention. FIG. 5 is a schematic diagram showing a pattern forming direction of a continuous pattern according to still another embodiment of the present invention. Referring to FIG. 4, in an embodiment, the continuous graphic 404 is composed of a starting point 404a, an ending point 404b, and n graphic connecting points 404c. According to the continuous graphic 404, the starting point 404a passes through the graphic connecting points 404c1, 404c to 404c (n-2). ), 404c(n-1), 404cn, etc., the order of the n graphics connection points 404c reaching the end point 404b, and the formation direction of the two adjacent two points on the continuous pattern 404 can be obtained to obtain a continuous graphic 404 pattern formation. The direction is clockwise. Referring to FIG. 5, in this embodiment, although the continuous graphic 504 is not a smooth gesture track, the method for determining the graphic forming direction of the continuous graphic 404 may be applied to the continuous graphic of FIG. 5 according to the above FIG. At 504, the pattern forming direction of the continuous pattern 504 can be obtained as an inverse clock direction.

Then, in step S117, the image rotation operation of the image 202 displayed on the display 200 is performed in accordance with the graphic formation direction 210. That is, the image forming direction 210 of the continuous pattern 204 is a rotation direction, and the image 202 displayed by the display 200 is rotated. That is, when the formation direction of the continuous pattern 204 is the clockwise direction, the image 202 displayed by the display 200 is rotated clockwise by a predetermined angle. And this predetermined angle is, for example, a 90 degree angle. The method of rotating the image is, for example, rotating the image 202 by using the geometric center point of the image area 308 surrounded by the minimum outer boundary 306 as the central axis of rotation. In another embodiment, the image is rotated, for example, by rotating the image 202 with the geometric center point of the image 202 as the central axis of rotation. 2A to 2C, according to the input tool, that is, the finger, the pattern of the continuous pattern 204 formed on the display 200 forms the direction 210, and the geometric center point of the image 202 is the central axis of rotation, clockwise The image 202 is rotated at a 90 degree angle (as shown in Figure 2C).

In addition, when the user directly forms a graphic start action on the display 200, the graphic connection action after the start of the graphic start operation, and the input of a continuous graphic 204 of the final graphic end point action, the starting point on the continuous graphic is captured. The information of the end point and the graphic connection point is performed, and the image processing steps S103 to S113 shown in FIG. 1 are performed, and the image rotation processing operation in step S117 is triggered while the graphic end point operation is operating. That is, in the image rotation processing operation of the present invention, the user does not need to perform any image operation confirmation operation in addition to continuous graphic input, and only needs to directly input the continuous graphic on the display (ie, continuous graphic The input is a non-closed area input), and at the same time as the end of the graphic end, the image rotation operation is performed corresponding to the direction in which the continuous pattern is input.

In summary, in the present invention, a continuous graphic is directly formed on the display as an input, and according to the information of the input continuous graphic, whether the continuous graphic conforms to the non-closed area input and the pattern forming direction of the continuous graphic, and then completes At the same time as continuous graphic input, image rotation processing is performed on the image displayed on the display.
