FIG. 2 is a flow chart summarizing an image capture method according to an embodiment of the present invention. As shown in fig. 2, the image capturing method according to the embodiment of the present invention includes the following steps.
In step S201, the th image capturing unit 10 acquires a detected image of a photographic subject scene As described above, in the case where a plurality of subjects exist in the photographic subject scene, there may not be a sharp image of every of the plurality of subjects in the detected image due to the focusing ability limitation of the th image capturing unit 10, after which the process proceeds to step S202.
In step S202, the processing unit 30 determines whether a plurality of specific targets satisfying a th predetermined condition exist in the detected image, in embodiments of the present invention, the specific targets are human faces, for example, as will be described in detail below, the th predetermined condition may be that the number of the plurality of specific targets is 2 or more, further the th predetermined condition may be that a distance between two specific targets is less than a predetermined threshold distance in a case where two specific targets exist, alternatively, the th predetermined condition may be that a depth distance between two specific targets is less than a predetermined threshold depth distance in a case where two specific targets exist.
If a positive result is obtained in step S202, that is, a plurality of specific objects satisfying the predetermined condition are detected in the image, the process proceeds to step S203.
As will be described in detail below, in embodiments of the present invention, the th image of the subject scene may be the image of the subject scene acquired by the th image capturing unit 10 with of the plurality of specific targets as the focal points, the second image of the subject scene may be the image of the subject scene acquired by the second image capturing unit 20 with another of the plurality of specific targets as the focal points, and thereafter, the process proceeds to step S204.

In contrast, if a negative result is obtained in step S202, that is, a plurality of specific targets satisfying the predetermined condition of are not present in the detected image, the process proceeds to step S205.
In step S205, the processing unit 30 takes the detected image as the captured image of the photographic scene in embodiments of the present invention, the absence of specific objects in the detected image that satisfy the predetermined condition of represents only a single subject in the photographic scene, or only subjects in the plurality of subjects are subjects that need to be imaged sharp although a plurality of subjects are present, therefore, the processing unit 30 can directly take the th image capturing unit 10 to take the detected image of the photographic scene as the final captured image of the photographic scene.
As the image capturing method according to the embodiment of the present invention described with reference to fig. 2, in the case where a plurality of subjects exist in a subject scene, an image of each subject that requires sharp imaging can be obtained by judging that a plurality of specific targets satisfying the th predetermined condition exist in the detected image.
Hereinafter, to third examples of an image capturing method according to an embodiment of the present invention will be described in further detail with reference to with reference to fig. 3 to 8.
FIG. 3 is a flowchart further illustrating step example of an image capture method according to an embodiment of the invention, as shown in FIG. 3, example of an image capture method according to an embodiment of the invention includes the following steps.
In step S301, the th image capturing unit 10 acquires a detection image of a photographic subject scene As described above, in the case where a plurality of subjects exist in the photographic subject scene, there may not be a sharp image of every of the plurality of subjects in the detection image due to the focusing ability limitation of the th image capturing unit 10, after which the process proceeds to step S302.
In step S302, the processing unit 30 determines whether two specific objects are present in the detected image, in the th example of the image capturing method according to the embodiment of the present invention, whether two specific objects are present in the detected image is an example of the th predetermined condition described with reference to FIG. 2.
If a negative result is obtained in step S302, that is, if there are no two specific targets in the detection image, the process proceeds to step S308. in step S308, since there is only a single subject in the photographic scene, the processing unit 30 can directly acquire the th image capturing unit 10 the detection image of the photographic scene as the final captured image of the photographic scene.
In contrast, if a positive result is obtained in step S302, that is, two specific targets are present in the detection image, the process proceeds to step S303.
In step S303, the processing unit 30 determines the specific point on each specific target in embodiments of the present invention, the specific point on each specific target is, for example, the nose, eyes, etc. on a human face.
In step S304, the processing unit 30 acquires coordinate information of a specific point. Thereafter, the process proceeds to step S305.
In step S305, the processing unit 30 determines whether the distance between the specific points is less than a predetermined threshold distance, hi embodiments of the present invention, the processing unit 30 determines whether the distance between the noses on two faces is less than a predetermined threshold distance.
If a negative result is obtained in step S305 that the distance between the specific points is not less than the predetermined threshold distance, indicating that the distance between two faces, faces being subjects requiring no active photographing, is far, then the process proceeds to step S308. as described above, in step S308, the processing unit 30 may directly acquire the th image capturing unit 10 as the final captured image of the subject scene.
Conversely, if a positive result is obtained in step S305, i.e., the distance between the specific points is less than the predetermined threshold distance, indicating that the distance between the two faces is close enough, the two specific objects are performing the group-photo operation, and it is necessary to acquire clear images for both of the two specific objects. Then, the process proceeds to step S306.
In step S306, the processing unit 30 controls the acquisition of the th image of the subject scene by the th image capturing unit 10 and the acquisition of the second image of the subject scene by the second image capturing unit 20. the th image of the subject scene may be the image of the subject scene acquired by the th image capturing unit 10 with of the plurality of specific targets as the focal point, the second image of the subject scene may be the image of the subject scene acquired by the second image capturing unit 20 with of the plurality of specific targets as the focal point, and thereafter, the process proceeds to step S307.
In step S307, the processing unit 30 combines the th image and the second image as a captured image of the photographic scene, for example, the processing unit 30 replaces image data of the same photographic scene coordinates in the th image with image data corresponding to the second image, and takes the th image after the replacement as the captured image.
As in the th example of the image capturing method according to the embodiment of the present invention described with reference to fig. 3, it is determined whether two specific targets requiring sharp imaging exist in a subject scene, and in the case where two specific targets exist, the two specific targets are clearly imaged by the th image capturing unit 10 and the second image capturing unit 20, respectively, and captured images of the th image capturing unit 10 and the second image capturing unit 20 are combined, thereby ensuring that a captured image including clear imaging of the two specific targets requiring sharp imaging is acquired.
Fig. 4 is a schematic diagram illustrating a distance between specific points in a th example of an image capturing method according to an embodiment of the present invention at step .
As shown in FIG. 4, in the inspection image 40 of the photographic scene acquired by the th image capturing unit 10, the processing unit 30 determines that there are two specific targets, namely, the th specific target 41 and the second specific target 42. the processing unit 30 further acquires a distance L between the th specific point 411 on the th specific target 41 and the th specific point 412 on the second specific target 42. if the distance L is smaller than a predetermined threshold distance (for example, the predetermined threshold distance is 50cm), it indicates that the th specific target 41 and the second specific target 42 are performing a group-shot operation.
Fig. 5A to 5C are schematic diagrams further illustrating a process of obtaining a captured image in th example of the image capturing method according to the embodiment of the present invention.
After determining that the th specific target 41 and the second specific target 42 are performing a group-taking operation as shown in fig. 4, the processing unit 30 controls the th image capturing unit 10 to acquire a th image 51 of the photographed scene with the th specific target 41 as a focus as shown in fig. 5A, the th specific target 41 is sharply imaged at the th image 51, and further, the second specific target 42 is not sharply imaged because the second specific target 42 is not at the th image capturing unit 10.
Meanwhile, as shown in FIG. 5B, the processing unit 30 controls the second image capturing unit 20 to acquire a second image 52 of the photographed scene with the second specific target 42 as a focus, the second specific target 42 is clearly imaged in the second image 52, and furthermore, the th specific target 41 is not clearly imaged since the th specific target 41 is not at the focus position of the second image capturing unit 20.
Thereafter, as shown in FIG. 5C, the processing unit 30 combines the th image 51 and the second image 52 as a captured image 53 of the photographic scene in the captured image 53, both the th specific target 41 and the second specific target 42 obtain sharp imaging.
Fig. 6 is a flowchart further illustrating step of a second example of an image capturing method according to an embodiment of the present invention as shown in fig. 6, the second example of an image capturing method according to an embodiment of the present invention includes the following steps.
In step S601, the th image capturing unit 10 acquires a detection image of a photographic subject scene as described above, in the case where a plurality of subjects exist in the photographic subject scene, there may not be a clear image of every of the plurality of subjects in the detection image due to the focusing ability limitation of the th image capturing unit 10.
In step S602, the processing unit 30 determines whether two specific objects are present in the detected image, in a second example of the image capturing method according to the embodiment of the present invention, whether two specific objects are present in the detected image is an example of the predetermined condition described with reference to FIG. 2.
If a negative result is obtained in step S602, that is, two specific targets are not present in the detection image, the process proceeds to step S608 in step S608, since there is only a single subject in the photographic scene, the processing unit 30 can directly acquire th image capturing unit 10 the detection image of the photographic scene as the final captured image of the photographic scene.
In contrast, if a positive result is obtained in step S602, that is, two specific targets are present in the detection image, the process proceeds to step S603.
In step S603, the processing unit 30 determines the specific point on each specific target in embodiments of the present invention, the specific point on each specific target is, for example, the nose, eyes, etc. on a human face.
Unlike the th example described above with reference to fig. 3, in the second example of the image capturing method according to the embodiment of the present invention, the th image capturing unit 10 is a depth camera that can acquire depth information, the th image capturing unit 10 acquires a detection image of a photographic scene including depth information of each specific target, and thereafter, the process proceeds to step S605.
In step S605, the processing unit 30 determines whether the depth distance between the specific points is less than a predetermined depth threshold distance, hi embodiments of the present invention, the processing unit 30 determines whether the depth distance of the noses on the two faces is less than a predetermined threshold distance.
If a negative result is obtained in step S605 that the depth distance between the specific points is not less than the predetermined depth threshold distance, indicating that the front-rear distances of two faces, of which faces are not subjects that need to be actively photographed, are far apart, then the process proceeds to step S608, as described above, in step S608, the processing unit 30 may directly cause the -th image capturing unit 10 to acquire the detected image of the subject scene as the final captured image of the subject scene
In contrast, if a positive result is obtained in step S605, that is, the depth distance between the specific points is smaller than the predetermined depth threshold distance, indicating that the anteroposterior distances of the two faces are close enough, the two specific objects are performing the group photo operation, and it is necessary to acquire clear images for both the specific objects. Then, the process proceeds to step S606.
In step S606, the processing unit 30 controls the acquisition of the th image of the subject scene by the th image capturing unit 10 and the acquisition of the second image of the subject scene by the second image capturing unit 20. the th image of the subject scene may be the image of the subject scene acquired by the th image capturing unit 10 with of the plurality of specific targets as the focal point, the second image of the subject scene may be the image of the subject scene acquired by the second image capturing unit 20 with of the plurality of specific targets as the focal point, and thereafter, the process proceeds to step S607.
In step S607, the processing unit 30 combines the th image and the second image as a captured image of the photographic scene, for example, the processing unit 30 replaces image data of the same photographic scene coordinates in the th image with image data corresponding to the second image, and takes the th image after the replacement as the captured image.
As the second example of the image capturing method according to the embodiment of the present invention described with reference to fig. 6, it is determined whether two specific targets requiring sharp imaging exist in the subject scene, and in the case where two specific targets exist, the two specific targets are clearly imaged with the th image capturing unit 10 and the second image capturing unit 20, respectively, and the captured images of the th image capturing unit 10 and the second image capturing unit 20 are combined, thereby ensuring that a clearly imaged captured image including the two specific targets requiring sharp imaging is acquired.
Fig. 7 is a schematic diagram illustrating, at step , the depth distance between particular points in a second example of an image capture method according to an embodiment of the present invention.
As shown in fig. 7, in the inspection image 70 of the photographic scene acquired by the th image capturing unit 10, the processing unit 30 judges that there are two specific targets, i.e., the th specific target 71 and the second specific target 72, the processing unit 30 further acquires a depth distance D between the th specific point 711 on the th specific target 71 and the th specific point 712 on the second specific target 72, indicates that the th specific target 71 and the second specific target 72 are performing a composition operation if the depth distance D is smaller than a predetermined depth threshold distance (e.g., the predetermined depth threshold distance is 100cm), and thereafter, the operations performed by the processing unit 30 are as shown in fig. 5A to 5C, and a repeated description thereof will be omitted herein.

As described above, in the case where a plurality of subjects exist in the photographic scene due to the focusing capability limitation of the th image capturing unit 10, clear images of every of the plurality of subjects may not be present in the detection image.
Unlike the flows of fig. 3 and 6, whether or not there are more than two specific objects in the detected image is another example of the predetermined condition described with reference to fig. 2, in embodiments of the present invention, the specific object is, for example, a human face.
If a positive result is obtained in step S802, that is, more than two specific targets are present in the detection image, the process proceeds to step S804.
In step S804, the processing unit 30 selects two specific targets having the largest and second largest imaging areas, in this case, the two specific targets having the largest and second largest imaging areas are the specific targets closest to the -th image capturing unit 10, that is, the two specific targets having the largest and second largest imaging areas are determined as the specific targets requiring sharp imaging.
In contrast, if a negative result is obtained in step S802, that is, more than two specific targets are not present in the detection image, the process proceeds to step S803.
In step S803, the processing unit 30 further determines whether two specific objects exist in the detection image.
If a negative result is obtained in step S803, that is, if there are no two specific targets in the detection image, the process proceeds to step S808. in step S808, since there is only a single subject in the photographic scene, the processing unit 30 can directly acquire the th image capturing unit 10 the detection image of the photographic scene as the final captured image of the photographic scene.
In contrast, if a positive result is obtained in step S803, that is, two specific targets are present in the detection image, the process proceeds to step S805.
In step S805, the processing unit 30 determines whether the distance of two specific targets is less than a predetermined threshold distance. In the third example of the image capturing method according to the embodiment of the present invention, the predetermined threshold distance may be a predetermined threshold distance set for a parallel distance between specific points on each of the specific targets described with reference to fig. 3, or the predetermined threshold distance may be a predetermined threshold depth distance set for a depth distance between specific points on each of the specific targets described with reference to fig. 6.
If a negative result is obtained in step S805, that is, the distance between the two specific targets is not less than the predetermined threshold distance, that is, it indicates that the distance between the two faces is far, of which faces are not subjects requiring active photographing, or it indicates that the front-rear distance between the two faces is far, of which faces are not subjects requiring active photographing, then the process proceeds to step S808. as described above, in step S808, the processing unit 30 may directly acquire the th image capturing unit 10 as the final captured image of the photographic scene.
In contrast, if a positive result is obtained in step S805, that is, the distance of two specific targets is smaller than the predetermined threshold distance, the process proceeds to step S806.
