The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. Rather than all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. Referring to FIG. 1 , FIG. 1 is a flowchart of an image collection method according to an embodiment of the present invention. In this embodiment, the acquired image may be a facial feature of a human face, or may be an animal or plant, or other object, such as a traffic. The present invention is not limited, and the method includes the following steps: Step 101: After entering the photographing mode, determining a photographing area in the framing interface; wherein, in this embodiment, according to the electronic device (such as Different from the touch screen camera, or the non-touch screen camera, or the touch screen mobile phone with a camera function or the non-touch screen mobile phone, etc., the manner of determining the photographing area in the viewfinder interface is also different, for example, when the electronic device is a touch screen device. After the electronic device enters the photographing mode, the framing interface is displayed on the display screen of the electronic device, and the photographer touches the framing interface to select a desired photographing area, and the electronic device directly records the photographer on the framing interface. Touch track, which is the photographed area selected by the photographer; or The photographer draws a line segment on the touch screen, and the electronic device uses the line segment as a rectangular diagonal line to determine a rectangular area, which is a determined photographing area; or the electronic device takes the line segment drawn by the photographer as a radius, starting from the starting point , determine a circular area, which is the determined photographing area. When the electronic device is a non-touch screen device, the photographing area may be determined by a screen selection method, wherein the screen selection method is: dividing the screen on the electronic device into a series of regions, for example, The screen is divided into a total of 16 rectangular areas of 4*4, and each area is numbered. The photographer can input the number of the selected area through the input end of the electronic device to determine the photographing area. Of course, this embodiment can also be other screens. The division method is not limited here; or if the electronic device comes with an optional shape, for example, it can be rectangular, circular, photographer One of the shapes can be selected by typing of the electronic device, and the position and size of the shape in the framing interface can be adjusted by the selection of the electronic device to determine the photographing area.

It should be noted that the manner of determining the photographing area may be different according to the difference of the electronic device and the usage habit of the photographer, and may be other methods, which are not limited by the present invention. Step 102: Collect a location area of the subject in the framing interface;

In this step, the subject is described by taking a human face as an example, but the present invention is not limited thereto, that is, the electronic device acquires the position of the face of the subject in the framing interface by the face recognition technology, that is, the electronic device collects and is captured. The subject's eyes, nose, mouth, and the like are photographed, and based on the identified features and relationships of the subject's eyes, nose, mouth, and the like, the positional area of the subject's face in the framing interface is determined.

Wherein, the face recognition method has various determination manners, for example, a face recognition method with geometric features, and the geometric features in the method may be shapes such as an eye, a nose, a mouth, and the geometric relationship between them (such as mutual Distance between faces, etc.), face recognition method for eigenface (PCA), face recognition method for neural network, face recognition method for elastic map matching, face recognition method for line segment Hausdorff distance (LHD), support A face recognition method of a vector machine (SVM), etc., but is not limited thereto. These methods are well known to those skilled in the art and will not be described herein. Step 103: When the location area is in the photographing area, the photographing is automatically started; wherein the location area is in the photographing area, including: all coordinate points of the location area are all in the photographing area Or the partial coordinate point of the location area is at the edge of the photographing area, and the remaining coordinate points are all within the photographing area. For example, the framing interface of the electronic device is a plane coordinate, and the lower left corner of the framing interface is the origin of the plane coordinates, and M (in the normal case, M is greater than or equal to 4) specific coordinates are taken at the edges of the respective positions of the positional region. Point, the specific coordinate point, that is, the area on the coordinate axis The maximum or minimum coordinate point of the direction. When the M specific coordinate points are all located in the photographing area, the position area is located in the photographing area; or, when a minimum X value in a specific coordinate point of the position area is equal to an edge of the photographing area When the minimum X value of the specific coordinate value, the maximum X value in the specific coordinate point of the position area is less than or equal to the maximum X value of the specific coordinate value of the edge of the photographing area, or in a specific coordinate point of the position area When the maximum X value is equal to the maximum X value of the specific coordinate value of the edge of the photographing area, the minimum X value in the specific coordinate point of the position area is greater than or equal to the minimum X value of the specific coordinate value of the edge of the photographing area. And when a minimum Y value in a specific coordinate point of the location area is equal to a minimum Y value of a specific coordinate value of an edge of the photographing area, a maximum Y value in a specific coordinate point of the position area is less than or equal to The maximum Y value of the specific coordinate value at the edge of the photographing area, or the maximum Y value in the specific coordinate point of the position area is equal to the edge of the photographing area When the maximum Y value of the specific coordinate value, the minimum Y value in the specific coordinate point of the position area is greater than or equal to the minimum Y value of the specific coordinate value of the edge of the photographing area, the position area is located in the photographing area Or the location area coincides with the photographing area. It can be seen from the above technical solution that, compared with the prior art, the image collecting method provided by the embodiment of the present invention determines the photographing area as an ideal photographing area in the framing interface, and the collected position area of the photographed object is ideal. When taking a picture, the camera is taken to ensure the integrity of the captured image, thereby improving the camera efficiency and user satisfaction.

2 is a flowchart of a second method for image capture according to an embodiment of the present invention. The image capture method includes the following steps: Step 201: After entering a photographing mode, determine a framing interface. The photographing area; the method for determining the photographing area in the framing interface, and the shape of the photographing area are described in detail in the above embodiments, and details are not described herein again. Step 202: Collect a location area of the object in the framing interface; The method for collecting the location area of the object in the framing interface is described in the foregoing embodiment, and details are not described herein. It should be noted that the shape of the location area of the captured object may be any shape of the location area available in the existing image acquisition technology, and details are not described herein.

Step 203: Determine whether the location area is located in the photographing area; if yes, go to step 204; if no, go to step 205.

The determining whether the location area is located in the photographing area, and generally, by comparing the M coordinate points selected in the edges of the position area in each direction, are all located in the photographing area corresponding to The edge coordinate points in each direction, or part of the coordinate points are located at the edge of the photographing area, and the remaining coordinate points are all judged in the photographing area.

Step 204: Automatically start photographing; Optionally, in another embodiment, the method may further include: sending a photographing instruction before the photographing area is in the photographing area, and the photographing is automatically started. The sending a photographing instruction may be sending a photographing instruction by using a voice, for example, the voice may be “OK, taking a photo”, or “OK, automatically taking a photo after three seconds”, or sending a photographing instruction by voice. N seconds to start taking a picture, where N is less than or equal to 10 seconds, for example,

"OK, send a photo instruction, and wait for 4 seconds to start taking a photo"; or send a photo indication through the second light; wherein the second light and the first light are lights of different colors. Step 205: Determine a moving direction of the object to be photographed; wherein, determining a moving direction of the object to be photographed, generally has the following three modes: One way is: first calculating a center coordinate point of the position area and the photographing a central coordinate point of the region, and then determining a relative position of the central coordinate point of the positional region and a central coordinate point of the photographing region, and determining a moving direction of the subject according to the relative position. Another way is: selecting a specific coordinate point in each direction on the location area; and a specific coordinate point in each direction corresponding to the photographing area; wherein, in this embodiment, for the graph composed of edges The specific coordinate point is at least a coordinate point of each vertex of the graphic, and for a circle or an ellipse, the specific coordinate point is at least: a parallel X axis and a Y axis, and the circular or elliptical shape The tangent point of each point. The specific coordinate point is the maximum coordinate point or the minimum coordinate point of each direction of the area on the coordinate axis. Then, determining a relative position of a specific coordinate point in each direction on the position area and a specific coordinate point in each direction corresponding to the photographing area; determining a moving direction of the subject according to the relative position.

For example, if it is determined that a certain vertex of the location area (such as the front of the rectangle to the upper left vertex, etc.) does not enter the photographing area, the determined moving direction is: Move to the lower left direction. The voice of the prompt can be "Your upper right exceeds the photographing area, please move to the lower left direction", etc. Of course, other situations and so on, different voice files can be played for each different situation. Of course, in this embodiment, there is another case that when the photographing area is completely located in the position area, it is required to prompt the direction of the subject to be away from the lens. Of course, the photographing area in the framing interface may also be prompted to be re-determined. , or increase the object distance. For example, the voice prompting the subject may be "farther from the lens" or the like; after that, it is determined whether the re-acquired location area is within the photographing area, and if the location area is within the photographing area, The photographing is automatically initiated; otherwise, the subject continues to be prompted to move away from the lens until the location area is within the photographing area. It should be noted that the foregoing is only an example. When the location area is not in the photographing area, the manner of determining the moving direction of the object to be photographed may be other manners, which is not limited herein.

Step 206, prompting the subject to move in a determined moving direction; after the moving of the subject is completed, performing step 202 again until the location area is located in the photographing area. Optionally, the manner of prompting the subject to move in a determined moving direction comprises: prompting, by the sound or the first light, the subject to move in the determined moving direction.

The moving the object to the determined direction by the sound includes: by, for example, "Please Left", "Please Right", "Please Up", "Please Down", and the like Prompting to remind the subject to move in different directions, or to remind the subject to move in the determined moving direction by a different frequency prompting sound, for example, when the positional area of the subject is far from the When the photographing area is photographed, the prompting audio frequency gradually becomes higher; when the positional area of the photographed subject is close to the photographing area, the prompting audio frequency gradually becomes lower. The moving the object to the determined moving direction by the first light comprises: reminding the subject to move in the determined moving direction by a change in a color of the light, when the subject is When moving, the first prompt light generates a different color change according to the distance between the location area and the photographing area; or, the subject is moved to the determined movement by a frequency change of the light blinking When the position of the subject is away from the photographing area, the blinking frequency of the first prompt light gradually becomes higher; when the positional area of the photographed object is close to the photographing area, the The first prompt light flashes at a lower frequency. It should be noted that the foregoing embodiment is only an example, and the voice prompt and the first light prompting manner in the embodiment of the present invention may further include other prompt forms, which are not limited herein. The sending a photographing instruction in the embodiment may be that when the location area of the subject is located in the photographing area, the photographing instruction is immediately sent, or when the location area of the subject is located in the After the photographing area, a photographing instruction is sent after a certain time, and the subject can make some expressions or posture adjustments during the period of time. The prompting mode described in this embodiment helps the subject to adjust the position through the prompt mode of human-computer interaction, and automatically takes a photo to take a high-quality photo. It should be noted that the foregoing embodiment is only an example. The prompting sound and the second light prompting manner in the sending photographing instruction according to the embodiment of the present invention are not limited to the description of the above embodiment, and the user (ie, the photographer) can set it according to the usage habit. This is not a limitation. It can be seen from the above embodiments that the image collecting method provided by the embodiment of the present invention reminds the subject to move by means of human-computer interaction of sound or light prompting until the subject of the subject is in the framing interface. When the location area is in the photographing area, it is ensured that the photographed object can still capture an ideal photograph without being able to see the framing interface, thereby improving photographing efficiency and user satisfaction. For ease of understanding, the image acquisition method of the present invention will be described below by way of specific embodiments. In this embodiment, taking a camera or a mobile phone of a touch screen as an example, when the photographer performs self-photographing, the photographer and the subject are the same person. After entering the photographing mode, the photographer draws a touch trajectory by touching the touch screen of the camera or the mobile phone, and the camera or the mobile phone records the touch trajectory as a region boundary, and the photographer forms a diagonal line at the beginning and end of the screen as a diagonal line. a rectangular area, which is used as a photographing area, or as a radius of the photographer's connection point at the beginning and end of the screen, with the starting point as the center of the circle, forming a circle, which is used as a photographing area, and then the camera or The mobile phone is fixed, the photographer enters the scenic spot as the subject, collects the facial features of the subject, and obtains a positional area by the face recognition method. Generally, the face recognition method obtained by the face recognition method takes a rectangular area as an example. However, it is not limited thereto, and the method for face recognition is as described above, and details are not described herein again. In this embodiment, the framing interface is used as a two-dimensional plane, and all coordinate points on the framing interface are used as the coordinate origin of the two-dimensional plane with the lower left corner of the framing interface, and the edge and the location of the photographing area. Each position in the photographing area may have a corresponding coordinate value, and the edge of the position area and each position inside the position area may also have corresponding coordinate values. In this embodiment, each of the position areas is selected. Specific coordinate points of the direction, in this embodiment, for the convenience of description, the specific coordinate points in each direction take the coordinate points of the four vertices of the rectangle as an example, that is, Define the upper left vertex on the position area as point A, the coordinates are (X0, Y0), the upper right vertex is B, the coordinates are (XI, Y1), the lower left vertex is C point, the coordinate is (X2, Y2), the lower right The vertex is D and the coordinates are (X3, Y3). Thus, for ease of calculation, the coordinates of the center point E of the rectangle can be recorded as (X4, Y4), where X4=( X0+X1+X2+X3 ) /4, Y4=( Y0+Y1+Y2+Y3 ) /4. Correspondingly, a specific coordinate point corresponding to each direction in the photographing area is selected, and the specific coordinate point in each direction is also taken as an example of the coordinate points of the four vertices of the rectangle, and the upper left vertex on the photographing area is defined as A' point. , the coordinates are (ΧΟ', Y0'), the upper right vertex is Β', the coordinates are (ΧΓ, ΥΓ), the lower left vertex is C' point, the coordinates are (Χ2', Υ2,), and the lower right vertex is D', coordinates For (Χ3', Υ3'), thus, for the convenience of calculation, the center point 所述 of the rectangle can be recorded, and the coordinates are (Χ4,, Υ4,), where Χ4,=( Χ0, +ΧΓ+Χ2, +Χ3, ) /4, Υ4,= ( Υ0, +ΥΓ+Υ2, +Υ3,) /4.

Comparing the coordinate points of B, C, and D on the position area with the coordinates of A, B, C, and D on the photographing area, and the coordinates of the four coordinate points, when the A, B, and C The two-dimensional coordinate values of D are all within the range of the coordinate values of the A', B', C', D', or when the coordinate values of the A, B are equal to the coordinates of the A', B' When the C and D coordinate values are within the range of the coordinate values of the C' and D', or the C coordinate values are equal to the coordinate values of the A, C, and the B, When the two coordinate values are within the range of the B', D' coordinate values, the location area is located in the photographing area; when the positional areas A, B, C, and D coordinate points are all When the A, B, C, and D' coordinate points of the photographing area are equal, the position area coincides with the photographing area.

When the location area is located in the photographing area or the position area coincides with the photographing area, the camera or the mobile phone outputs a photographing instruction by voice, such as "OK, a photo taking instruction of photographing after three seconds". , the camera or the mobile phone automatically takes a picture after three seconds. Of course, in the above process, when a part of the position area (such as the coordinate A) in the position area is not in the photographing area, since the coordinate point A is a rectangle upper left At the coordinate point, the camera or mobile phone plays the voice prompt of “Top left beyond the photo area, please move to the lower right”, prompting the subject to move. If other parts are not in the photo area, the camera or mobile phone is based on In different situations, different voice prompts are played by the subject to move, and when the location area is completely located in the photographing area, a photographing instruction is output, and a camera of the camera or the mobile phone is activated to automatically take a photograph of the subject. It should be noted that the foregoing embodiment is only an example. In the embodiment of the present invention, the shape of the location area, the comparison judgment manner, and the prompting manner are not limited thereto, and may also be different according to the choice of the photographer and the camera or the mobile phone, including other The method will not be described here. It should be pointed out that when taking photos of multiple people, the electronic device can number each recognized face, and each face has a corresponding number. By comparing each face and the photographed area, it is judged whether or not In the photographing area where all the faces are entered, if the corresponding face does not enter the photographing area, the electronic device performs a corresponding voice prompt for the face that does not enter the photographing area, and the manner of the comparison judgment and the manner of the prompt are as described above. The embodiments are similar and will not be described here. It should be noted that the object to be photographed is not limited to a person but also other objects, and the shape of the location area of the collected object may be any shape of a corresponding person or object available in the existing image acquisition technology. There are no restrictions here. It can be seen from the above technical solution that the image collection method provided by the embodiment of the present invention determines the location area by means of the character recognition, and adjusts the position of the location area by the manner of human interaction of the sound and the light prompt, when the position is When the area is in the photographing area, automatic photographing is triggered to ensure the integrity of the captured image, thereby improving the photographing efficiency and the user's satisfaction.
