[0013] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0015] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The terminology involved in the embodiments of this application is explained below.

[0016] The cropping box is a rectangle used to select the cropping area when cropping an image.

[0017] The image to be cropped is the image that needs to be cropped.

[0018] The image processing method and apparatus provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0019] It should be noted that the image processing method provided in this application can be executed by electronic devices such as mobile phones, tablets, laptops, PDAs, and in-vehicle electronic devices. Some embodiments of this application use electronic devices as the executing entity to illustrate the image processing method provided in this application.

[0020] The image processing method provided in this application can be applied to scenarios where images are cropped.

[0021] Figure 1 This is a schematic flowchart of an image processing method provided in some embodiments of this application. The image processing method includes the following steps: Step 101: Receive drag input for the first vertex of the first cropping box; wherein, the first cropping box includes multiple vertices, and the first vertex is any vertex of the first cropping box; In some embodiments of this application, the first cropping frame can be a rectangle. The first cropping frame has four vertices, and the first vertex can be any one of the four vertices.

[0022] Step 102: In response to drag input, determine the number of vertices of the first cropping box located outside the first image; In some embodiments of this application, the first image in the embodiments of this application can be a convex quadrilateral that has been processed from a certain image, such as horizontal scaling, vertical scaling, rotation, etc.

[0023] In some embodiments of this application, in step 102, when dragging the first vertex of the first cropping frame causes the first cropping frame to have vertices located outside the first image, the number of vertices of the first cropping frame located outside the first image is determined. When the first cropping frame has vertices located outside the first image, the number of vertices of the first cropping frame located outside the first image may be 1, 2, or 3.

[0024] In some embodiments of this application, when cropping an image using a cropping box, if a user drags a vertex of the cropping box, the drag point needs to move with the user's finger or a touch device such as a stylus, causing the cropping box to extend beyond the image area. To confine the cropping box within the image area, all cropping box vertices extending beyond the image area need to be translated into the image area. Due to factors such as the number of cropping box vertices outside the image area, the position of the drag point, the orientation of the cropping box vertices outside the image area relative to the image area, and the shape of the image area, there are many scenarios where the cropping box extends beyond the image area.

[0025] This application categorizes scenarios where the cropping box extends beyond the image area into two types: Type 1: only one cropping box vertex is located outside the image area; Type 2: two or three cropping box vertices are located outside the image area. Different cropping box adjustment strategies are configured for Type 1 and Type 2 scenarios respectively.

[0026] Figure 2 This is a schematic diagram showing that the number of vertices of the cropping frame located outside the image is 1, according to some embodiments of this application; Figure 3 This is a schematic diagram of a cropping frame with two vertices located outside the image, provided in some embodiments of this application. Figure 4 This is a schematic diagram of a cropping frame located outside the image with 3 vertices, provided in some embodiments of this application.

[0027] exist Figures 2 to 4 In the diagram, point P is the drag point. Figure 2 In the image 201, the number of vertices of the cropping box 202 located outside the image 201 is 1; Figure 3 In the image 201, the number of vertices of the cropping box 202 located outside the image 201 is 2; Figure 4 In the image 201, the number of vertices of the cropping box 202 located outside the image 201 is 3.

[0028] Step 103: Adjust the first cropping box according to the cropping box adjustment strategy corresponding to the quantity to obtain the second cropping box; wherein, all four vertices of the second cropping box are located inside the first image; In some embodiments of this application, step 103 may include: when the number of vertices of the first cropping frame located outside the first image is 1, adjusting the first cropping frame according to the positional relationship between the second vertex, the intersection point, and the vertices of the first image to obtain a second cropping frame; wherein, the second vertex is the vertex of the first cropping frame located outside the first image, and the intersection point is the intersection of the diagonals of the first image.

[0029] In some embodiments of this application, the positional relationship between the vertex of the first cropping frame located outside the first image, the intersection of the diagonal of the first image, and the vertex of the first image can be such that the intersection of the vertex of the first cropping frame located outside the first image and the diagonal of the first image is located in the diagonal quadrant of a certain vertex of the first image, or that the intersection of the vertex of the first cropping frame located outside the first image and the diagonal of the first image is not located in the diagonal quadrant of any vertex of the first image, that is, the intersection of the vertex of the first cropping frame located outside the first image and the diagonal of the first image is not located in the diagonal quadrant of any vertex of the first image.

[0030] In some embodiments of this application, adjusting the first cropping frame to obtain the second cropping frame based on the positional relationship between the second vertex, the center point, and the vertices of the first image may include: when the second vertex and the center point are respectively located in the diagonal quadrants of the third vertex, adjusting the second vertex to the position of the third vertex to obtain the second cropping frame; wherein the third vertex is any vertex of the first image.

[0031] For example, such as Figure 5 As shown, Figure 5 This is a first schematic diagram illustrating the adjustment of the first clipping frame according to some embodiments of this application. Figure 5 In the image, the four vertices of the cropping box 202 are vertices A, B, C, and D, and the four vertices of the image 201 are vertices X, Y, Z, and M. Point O is the intersection of the two diagonals XZ and YM of the image 201. Since vertex A of the cropping box 202 and point O are located in the diagonal quadrant opposite vertex X of the image 201, vertex A of the cropping box 202 is adjusted to the position of vertex X of the image 201.

[0032] In some embodiments of this application, adjusting the first cropping frame to obtain the second cropping frame based on the positional relationship between the second vertex, the center point, and the vertices of the first image may include: when the second vertex and the center point are not respectively located in the diagonal quadrants of the vertices of the first image, obtaining a first distance from the second vertex in the horizontal direction to the first image and a second distance from the second vertex in the vertical direction to the first image; translating the second vertex to the first image according to the translation method corresponding to the target distance; wherein, the target distance is the minimum distance between the first distance and the second distance.

[0033] For example, such as Figure 6 As shown, Figure 6 This is a second schematic diagram illustrating the adjustment of the first clipping frame according to some embodiments of this application. Figure 6In the image, the four vertices of the cropping box 202 are vertices A, B, C, and D, and the four vertices of the image 201 are vertices X, Y, Z, and M. Point O is the intersection of the two diagonals XZ and YM of the image 201. Vertices A and O of the cropping box 202 are not located in the diagonal quadrants of vertex X, Y, Z, or M of the image 201; that is, vertices A and O of the cropping box 202 are not located in the diagonal quadrants of any vertex of the image 201. At this point, obtain the horizontal distance from vertex A of cropping frame 202 to image 201 and the vertical distance from vertex A of cropping frame 202 to image 201. Compare the two distances to obtain the minimum distance between the horizontal and vertical distances of vertex A of cropping frame 202 to image 201. The minimum distance between the horizontal and vertical distances of vertex A of cropping frame 202 to image 201 is the vertical distance of vertex A of cropping frame 202 to image 201. Then, translate vertex A of cropping frame 202 vertically to image 201.

[0034] In some embodiments of this application, step 103 may include: when the number is 2 or 3, controlling the first side to be horizontally translated to the first image to obtain the third side, and controlling the second side to be vertically translated to the first image to obtain the fourth side; wherein, the first side is a vertical side adjacent to the first vertex, and the second side is a horizontal side adjacent to the first vertex; updating the first vertex to the intersection of the third side and the fourth side to obtain the third cropping frame; and determining the second cropping frame according to the number of vertices of the third cropping frame located outside the first image.

[0035] In some embodiments of this application, determining the second cropping frame based on the number of vertices outside the first image of the third cropping frame may include: when the number of vertices outside the first image of the third cropping frame is 0, using the third cropping frame as the second cropping frame; when the number of vertices outside the first image of the third cropping frame is 1, adjusting the third cropping frame according to the positional relationship between the fourth vertex, the intersection point, and the vertices of the first image to obtain the second cropping frame; wherein the fourth vertex is the vertex of the third cropping frame outside the first image, and the intersection point is the intersection of the diagonals of the first image.

[0036] For example, such as Figure 7 As shown, Figure 7 This is a third schematic diagram illustrating the adjustment of the first clipping frame according to some embodiments of this application. Figure 7In the image, the four vertices of the cropping box 202 are vertices A, B, C, and D, and the four vertices of the image 201 are vertices X, Y, Z, and M. Vertex A of the cropping box 202 is the drag point. When dragging vertex A, vertices B and D of the cropping box 202 are located outside of the image 201, meaning that the number of vertices of the cropping box 202 located outside the image 201 is 2. Horizontally translate edge AB to the first image to obtain edge A1B1, and vertically translate edge AD to the first image to obtain edge A2D1; the intersection of edge A1B1 and edge A2D1 is A3. Then, update vertex A of the cropping box 202 to A3. At this time, vertex B of the cropping box 202 is updated to B1, and vertex D of the cropping box 202 is updated to D1. All vertices of the cropping frame A3B1CD1 are located inside the image 201, and the number of vertices of the cropping frame A3B1CD1 located outside the image 201 is 0. Therefore, the cropping frame A3B1CD1 is the second cropping frame in this embodiment of the application.

[0037] For example, such as Figure 8 As shown, Figure 8 This is a fourth schematic diagram illustrating the adjustment of the first clipping frame according to some embodiments of this application. Figure 8 In the image, the four vertices of the cropping box 202 are vertices A, B, C, and D, and the four vertices of the image 201 are vertices X, Y, Z, and M. Vertex A of the cropping box 202 is the drag point. When dragging vertex A, vertices A and D of the cropping box 202 are located outside of image 201, meaning the number of vertices of the cropping box 202 located outside of image 201 is 2. Vertically translating edge AB to the first image yields edge A2B1, and horizontally translating edge AD to the first image yields edge A1D1. The intersection of edge A2B1 and edge A1D1 is A3. Therefore, vertex A of the cropping box 202 is updated to A3. At this time, vertex B of the cropping box 202 is updated to B1, and vertex D of the cropping box 202 is updated to D1. The vertex of the cropping box A3B1CD1 located outside of image 201 is A3, meaning the number of vertices of the cropping box A3B1CD1 located outside of image 201 is 1.

[0038] Vertex A3 and point O of cropping box 202 are not located in the diagonal quadrant of vertex X of image 201, nor in the diagonal quadrant of vertex Y of image 201, nor in the diagonal quadrant of vertex Z of image 201, nor in the diagonal quadrant of vertex M of image 201. That is, vertex A3 and point O of cropping box 202 are not located in the diagonal quadrant of any vertex of image 201. At this point, obtain the horizontal distance from vertex A3 of cropping frame 202 to image 201 and the vertical distance from vertex A3 of cropping frame 202 to image 201. Compare the two distances to obtain the minimum distance between the horizontal and vertical distances of vertex A3 of cropping frame 202 to image 201. The minimum distance between the horizontal and vertical distances of vertex A3 of cropping frame 202 to image 201 is the horizontal distance of vertex A3 of cropping frame 202 to image 201. Then, translate vertex A3 of cropping frame 202 horizontally to image 201.

[0039] For example, such as Figure 9 As shown, Figure 9 This is a fifth schematic diagram illustrating the adjustment of the first clipping frame according to some embodiments of this application. Figure 9 In the image, the four vertices of cropping box 202 are vertices A, B, C, and D, and the four vertices of image 201 are vertices X, Y, Z, and M. Vertex A of cropping box 202 is the drag point. When dragging vertex A, vertices A, B, and D of cropping box 202 are located outside image 201, meaning the number of vertices of cropping box 202 located outside image 201 is 3. Vertically translating edge AD to the first image yields edge A1D1, and horizontally translating edge AB to the first image yields edge A2B1. The intersection of edge A1D1 and edge A2B1 is A3. Therefore, vertex A of cropping box 202 is updated to A3. At this time, vertex B of cropping box 202 is updated to B1, and vertex D of cropping box 202 is updated to D1. The vertex of cropping box A3B1CD1 located outside image 201 is A3, meaning the number of vertices of cropping box A3B1CD1 located outside image 201 is 1.

[0040] Vertex A3 and point O of cropping box 202 are not located in the diagonal quadrant of vertex X of image 201, nor in the diagonal quadrant of vertex Y of image 201, nor in the diagonal quadrant of vertex Z of image 201, nor in the diagonal quadrant of vertex M of image 201. That is, vertex A3 and point O of cropping box 202 are not located in the diagonal quadrant of any vertex of image 201. At this point, obtain the horizontal distance from vertex A3 of cropping frame 202 to image 201 and the vertical distance from vertex A3 of cropping frame 202 to image 201. Compare the two distances to obtain the minimum distance between the horizontal and vertical distances of vertex A3 of cropping frame 202 to image 201. The minimum distance between the horizontal and vertical distances of vertex A3 of cropping frame 202 to image 201 is the horizontal distance of vertex A3 of cropping frame 202 to image 201. Then, translate vertex A3 of cropping frame 202 horizontally to image 201.

[0041] Step 104: Crop the first image using the second cropping frame.

[0042] In some embodiments of this application, in step 104, the portion of the first image selected by the second cropping frame can be cropped.

[0043] In this embodiment, a drag input is received for a first vertex of a first cropping frame; wherein the first cropping frame includes multiple vertices, and the first vertex is any one of the vertices of the first cropping frame; in response to the drag input, the number of vertices of the first cropping frame located outside the first image is determined; the first cropping frame is adjusted according to a cropping frame adjustment strategy corresponding to the number of vertices, resulting in a second cropping frame; wherein all four vertices of the second cropping frame are located inside the first image; the first image is cropped using the second cropping frame. Thus, by adjusting the cropping frame according to a cropping frame adjustment strategy corresponding to the number of vertices located outside the image to be cropped, cropping frame jumps can be prevented, ensuring that the cropped image meets the user's requirements.
