Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a shooting method, device, equipment and computer-readable storage medium. Background Art

[0002] The terminal can be equipped with multiple shooting lenses, but when shooting, generally only one of the lenses is selected for shooting.

[0003] However, the shooting lens selected by the user may not be able to capture the target object in the shooting picture clearly.

[0004] For example, when a user wants to take a picture of a person or scenery from a distance, he or she uses a wide-angle lens with a large field of view. However, the clarity of the distant view is limited by the wide-angle lens, resulting in unclear shots of the target object. For example, there may be a certain loss in image quality when enlarging the face area after shooting.

[0005] For example, when a user uses a telephoto lens to shoot a distant landscape, if there is a face near the lens, the face will be blurred and not clear enough.

[0006] In the related technology, after the lens recognizes the target object, special automatic exposure (AE), automatic white balance (AWB) and auto focus (AF) adjustments are performed on the area where the target object is located, and an enhancement algorithm for the target object is used to optimize the clarity of the area.

[0007] However, the optimization scheme in the related art only compensates the lens from a software perspective and cannot break through the hardware limitations of the shooting lens selected by the user, and the compensation effect is extremely limited. Summary of the invention

[0008] In order to overcome the problems existing in the related art, the present disclosure provides a shooting method, device, equipment and computer-readable storage medium, which can solve the above problems.

[0009] According to a first aspect of an embodiment of the present disclosure, a shooting method is provided, which is executed by a terminal, and the terminal is equipped with multiple shooting lenses. The method includes: determining a first focusing distance between a target object and a first shooting lens currently in use; selecting a second shooting lens according to the first focusing distance, and shooting the target object through the second shooting lens to generate a first image, wherein the shooting clarity of the target object by the second shooting lens is better than that of the first shooting lens; and replacing the area of ​​the target object in the first image with the position of the target object in the second image shot by the first shooting lens.

[0010] According to a second aspect of an embodiment of the present disclosure, a shooting device is provided, which is configured in a terminal, and the terminal is equipped with multiple shooting lenses. The device includes: a determination unit, configured to determine a first focusing distance between a target object and a first shooting lens currently in use; a shooting unit, configured to select a second shooting lens according to the first focusing distance, and shoot the target object through the second shooting lens to generate a first image, wherein the shooting clarity of the target object by the second shooting lens is better than that of the first shooting lens; a replacement unit, configured to replace the area of ​​the target object in the first image with the position of the target object in the second image shot by the first shooting lens.

[0011] According to a third aspect of an embodiment of the present disclosure, an electronic device is provided, including: a processor and a memory; the memory is used to store a computer program; the processor is used to execute the shooting method as described in the first aspect by calling the computer program.

[0012] According to a fourth aspect of an embodiment of the present disclosure, there is provided a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, the shooting method as described in the first aspect is implemented.

[0013] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0014] The present disclosure determines a first focus distance of a target object, selects a second camera lens that can take clearer photos according to the first focus distance, and replaces the corresponding position of the image taken by the first camera lens with the target object taken by the second camera lens, so that when a user uses the first camera lens to take photos, the clarity of the target object in the image is higher than expected. The present disclosure uses the second camera lens to take photos of the target object, and synthesizes the image obtained by the photo with the image obtained by the first camera lens, so that the user can obtain a higher definition image even if the user uses the first camera lens to take photos.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1The present invention is a schematic flow chart of a shooting method according to an embodiment of the present invention, and the shooting method can be performed by a terminal. The terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc., and the terminal is equipped with multiple shooting lenses.

[0027] like Figure 1 As shown, the shooting method includes:

[0028] In step S101, a first focusing distance between a target object and a first shooting lens currently in use is determined;

[0029] In step S102, a second shooting lens is selected according to the first focusing distance, and the target object is photographed by the second shooting lens to generate a first image, wherein the second shooting lens has a better shooting clarity for the target object than the first shooting lens;

[0030] In step S103, the area of ​​the target object in the first image is replaced with the position of the target object in the second image captured by the first shooting lens.

[0031] In some embodiments, the terminal is equipped with multiple shooting lenses, and the multiple shooting lenses may include: a main wide-angle lens (wide), an ultra-wide-angle lens (ultrawide), and a telephoto lens (tele).

[0032] Among them, the main wide-angle lens is usually the most commonly used lens for terminals, adapting to most application scenarios and able to meet most of the users' shooting needs; the field of view of the ultra-wide-angle lens is larger than that of the main wide-angle lens, but the relative focusing distance is smaller than that of the main wide-angle lens; the field of view of the telephoto lens is smaller than that of the main wide-angle lens, but the focusing distance is greater than that of the main wide-angle lens.

[0033] In some embodiments, in the default photo mode, the magnification is 0.5 to 1 times for the ultra-wide-angle focal length, the magnification is 1 to 3 times for the wide-angle focal length, and the magnification is above 3 times for the telephoto focal length; or, the magnification is 0.5 to 1 times for the ultra-wide-angle focal length, the magnification is 1 to 5 times for the wide-angle focal length, and the magnification is above 5 times for the telephoto focal length.

[0034] It should be noted that the above embodiment is only an illustrative example of the present disclosure and cannot limit the present disclosure. In fact, the focal length corresponding to the magnification can be flexibly set according to needs.

[0035] In some embodiments, the terminal may determine the first focus distance according to the image distance of the image of the target object presented by the first shooting lens.

[0036] The first focusing distance refers to the distance from the target object to the presented image.

[0037] Different shooting lenses correspond to different focus ranges. When a target object is within the focus range of the shooting lens, the shooting lens can focus on the target object, and the captured image has a higher definition.

[0038] In some embodiments, the target object may include a human face.

[0039] In general, users hope that the faces in the captured images are clearer, so the target object may include the face, so that during the shooting process, when the terminal recognizes the face, the method proposed in the present disclosure is executed, so that the face in the captured image is clearer, giving the user a better experience.

[0040] In some embodiments, the target object may also include an object within a range area selected by a user.

[0041] The user can select a range area on the preview image by clicking, selecting a frame, etc., and identify the range area or the object within the range area as the target object.

[0042] The user can select the content of interest to make the content of interest clearer in the captured image.

[0043] In some embodiments, the terminal can determine whether the first focusing distance of the target object is within the focusing range of the first camera lens. If it is within the focusing range of the first camera lens, it indicates that the first camera lens is able to focus on the target object, and the clarity of the target object in the captured image is relatively high. At this time, there is no need to select the second camera lens; if the first focusing distance of the target object is outside the focusing range of the first camera lens, it indicates that the first camera lens is unable to focus on the target object, and the clarity of the target object in the captured image is relatively low. If the user zooms in on the target object area, the image quality of the target object will be greatly lost.

[0044] In some embodiments, when it is determined that a first focusing distance of the target object is outside the focusing range of a first shooting lens, a second shooting lens is selected according to the first focusing distance, and the target object is photographed by the second shooting lens to generate a first image, wherein the shooting clarity of the target object by the second shooting lens is better than that of the first shooting lens.

[0045] In some embodiments, the first focus distance of the target object is within the focus range of the second shooting lens.

[0046] In this case, the second shooting lens can focus on the target object, and the image of the target object captured by the second shooting lens must be clearer than that captured by the first shooting lens outside the focus range.

[0047] In some embodiments, the first focus distance of the target object is outside the focus ranges of the first photographing lens and the second photographing lens, but closer to the focus range of the second photographing lens.

[0048] In this case, although neither the first camera lens nor the second camera lens can focus on the target object, since the target object is closer to the focusing range of the second camera lens, even if neither the first camera lens nor the second camera lens can focus, the image of the target object obtained by the second camera lens is still clearer than the image of the target object obtained by the first camera lens.

[0049] In some embodiments, the area of ​​the target object in the first image is replaced with the position of the target object in the second image captured by the first shooting lens.

[0050] Since the image of the target object captured by the second camera lens will be clearer, the area where the target object is located in the first image can be replaced with the corresponding position in the image captured by the first camera lens through image synthesis, so that the user can obtain a clearer image of the target object when shooting with the first camera lens.

[0051] The present disclosure uses a second camera lens to shoot a target object, and after shooting, replaces the relatively clear target object area captured by the second camera lens with the corresponding position of the image captured by the first camera lens used by the user through image synthesis, so that when the user uses the first camera lens to shoot an image, the target object can have better clarity, thereby improving the user experience.

[0052] In some embodiments, the minimum focusing distance of the lens may be used to determine whether the target object can be focused by the shooting lens, so as to determine a second shooting lens with higher shooting clarity.

[0053] Generally, different shooting lenses have different focus ranges, and there is no overlap in the focus ranges. Therefore, it can be considered that when the first focus distance corresponding to the target object is greater than the minimum focus distance of the shooting lens, the shooting lens can obtain a clearer image, and the closer the minimum focus distance of the shooting lens is to the first focus distance, the clearer the image is.

[0054] In some embodiments, the selecting the second shooting lens according to the first focusing distance includes: when the minimum focusing distance of the first shooting lens is greater than the first focusing distance, the minimum focusing distance of the selected second shooting lens is less than the first focusing distance and the target object is within the field of view angle of the second shooting lens; when the minimum focusing distance of the first shooting lens is less than the first focusing distance, the minimum focusing distance of the selected second shooting lens is less than the first focusing distance but greater than the minimum focusing distance of the first shooting lens and the target object is within the field of view angle of the second shooting lens.

[0055] The following will be Figure 2 and Figure 3 The embodiment of the present invention specifically introduces how to select the second shooting lens.

[0056] Figure 2 It is a schematic diagram showing a method of selecting a second shooting lens according to a first focusing distance according to an embodiment of the present disclosure.

[0057] like Figure 2 As shown, terminal 210 has three shooting lenses, namely lens 1, lens 2, and lens 3. The minimum focusing distances corresponding to the three lenses are shown in the figure, from near to far, they are the minimum focusing distance of lens 1, the minimum focusing distance of lens 2, and the minimum focusing distance of lens 3, that is, the minimum focusing distance of lens 1 is smaller than the minimum focusing distance of lens 2, which is smaller than the minimum focusing distance of lens 3.

[0058] in, Figure 2 3 possible positions of the target object are shown in the figure, position 1 is between the minimum focusing distance of lens 1 and the minimum focusing distance of lens 2, position 2 is between the minimum focusing distance of lens 2 and the minimum focusing distance of lens 3, and the first focusing distance of position 3 is greater than the minimum focusing distance of lens 3.

[0059] When the first shooting lens selected by the user is lens 3, and the position of the target object is at position 2, the minimum focusing distance of the first shooting lens is greater than the first focusing distance. Without considering the field of view angle, the second shooting lens selected according to the first focusing distance can be lens 1 and lens 2 whose minimum focusing distance is less than that of position 2. Among them, since the minimum focusing distance of lens 2 is closer to position 2 than the minimum focusing distance of lens 1, if lens 2 is used, the image of the target object captured will be clearer than the image of the target object captured with lens 1.

[0060] When the first shooting lens selected by the user is lens 1, and the position of the target object is at position 3, the minimum focusing distance of the first shooting lens is less than the first focusing distance. Without considering the field of view angle, the second shooting lens selected according to the first focusing distance can be lens 2 and lens 3, whose minimum focusing distance is less than the first focusing distance but greater than the minimum focusing distance of lens 1. Among them, since the minimum focusing distance of lens 3 is closer to position 3 than the minimum focusing distance of lens 2, if lens 3 is used, the image of the target object captured will be clearer than the image of the target object captured by lens 2.

[0061] Of course, the above embodiment is only a specific example. According to the minimum focusing distance of the first shooting lens and the first focusing distance, there are many situations to select a suitable second shooting lens, which are not listed one by one in the present disclosure.

[0062] In some embodiments, in addition to determining the second photographing lens according to the minimum focusing distance of the plurality of photographing lenses and the first focusing distance, the second photographing lens also needs to meet the condition that the target object is included in the field of view.

[0063] Figure 3 is a schematic diagram showing a field of view angle of a shooting lens according to an embodiment of the present disclosure.

[0064] like Figure 3 As shown, the minimum focusing distances of the three lenses of terminal 210, lens 1, lens 2, and lens 3 are as follows: Figure 2 As shown, the field of view of each lens can be found in Figure 3 , the field of view angle of lens 1 with the smallest minimum focusing distance is the largest, and the field of view angle of lens 3 with the largest minimum focusing distance is the smallest.

[0065] The field of view of the selected second camera lens must include the target object. If the field of view of the camera lens does not include the target object, when the terminal is at the current position, the target object will be outside the image range captured by the camera lens, that is, the target object cannot be photographed.

[0066] For example, when the first shooting lens is lens 1, the position of the target object is at position 4. At this time, based on the judgment of the above-mentioned minimum focusing distance, the second shooting lens that can be used can be lens 2 and lens 3, among which the shooting effect of lens 3 is clearer. However, since position 4 is outside the field of view of lens 3, if lens 3 is used for shooting, the target object will not exist in the captured image. Therefore, at this time, only lens 2 whose field of view includes position 4 can be selected as the second shooting lens.

[0067] In summary, when selecting the second shooting lens, the shooting lens with higher shooting clarity can be determined based on the relationship between the minimum focusing distance and the first focusing distance, and whether the target object can appear in the image captured by the shooting lens can be determined based on the field of view of the lens and the position of the target object.

[0068] In some embodiments, the terminal further includes an optical image stabilizer (OIS), and the target object is within the field of view of the second camera lens, including: the target object is within the field of view of the second camera lens after being compensated by the OIS.

[0069] The terminal can compensate for the field of view angle through OIS to expand the field of view angle range of the lens, so that the target object can be located within the field of view angle of more shooting lenses.

[0070] For example, taking tele (telephoto lens) as an example, since the field of view of the tele lens is only the middle part of the field of view of wide (main camera wide-angle lens), such as one-third or one-fifth. Therefore, when the first shooting lens is a wide lens, the target object detected by the wide lens has a greater probability of falling outside the field of view of the tele, making it impossible to select the tele lens as the second shooting lens due to the field of view, so that the target object in the final captured image cannot achieve the ideal clarity. Therefore, in order to reduce the inability to select the shooting lens as the second shooting lens due to the field of view, an OIS device can be used to move the tele lens to perform a small amount of field of view compensation.

[0071] For example, a tilt-shift OIS motor can offset ±0.5°, which is more than one-fiftieth of the tele field of view. If a pan-type closed-loop OIS motor is used, it can compensate for larger jitters, and the maximum compensation angle can generally reach ±1.5°, which is about one-tenth of the tele field of view.

[0072] By compensating the field of view angle through OIS, the probability of the target object being within the field of view angle of the shooting lens can be increased, the probability of using the shooting method proposed in the present disclosure can be increased, and the selection range of the second shooting lens can also be increased.

[0073] In some embodiments, the multiple shooting lenses include a wide-angle lens, a main camera lens and a telephoto lens, wherein the minimum focusing distance of the wide-angle lens is smaller than the minimum focusing distance of the main camera lens, and the minimum focusing distance of the main camera lens is smaller than the minimum focusing distance of the telephoto lens.

[0074] The multiple shooting lenses of the terminal include an (ultra) wide - angle lens (ultrawide), a main camera (wide - angle) lens (wide), and a telephoto lens (tele). In some embodiments, the minimum focusing distance of the main camera lens can be 15 - 25 cm, the minimum focusing distance of the telephoto lens can be 80 - 120 cm, and the minimum focusing distance of the ultra - wide - angle lens is less than 15 cm.

[0075] Figure 4A 、 4B Figure 4C is a schematic diagram of selecting a second shooting lens according to an embodiment of the present disclosure.

[0076] The following will be combined with Figure 4A 、 4B Figure 4C to list some feasible selections of the second shooting lens.

[0077] The order of the minimum focusing distances of the three lenses from small to large is: ultrawide < wide < tele. The order of the field - of - view angles from large to small is: ultrawide > wide > tele.

[0078] As Figure 4A shown, when the first shooting lens is ultrawide, if the first focusing distance is greater than the minimum focusing distance of tele and within the field - of - view angle of tele, then using tele can obtain the clearest image of the target object. At this time, the second shooting lens can be tele; at the same time, the first focusing distance being greater than the minimum focusing distance of tele also means it is necessarily greater than the minimum focusing distance of wide. So when it is determined that the first focusing distance is greater than that of tele, but the target object is not within the field - of - view angle of tele, the wide lens can be considered. At this time, it is necessary to determine whether the target object is within the field - of - view angle of wide. If it is, the second shooting lens is wide; if not, the process ends. When the first focusing distance is less than the minimum focusing distance of tele, it is necessary to determine whether the first focusing distance is greater than the minimum focusing distance of wide. If not, it means the clearest shooting lens is the first shooting lens ultrawide, and the process ends. If it is greater, it is necessary to determine whether the target object is within the field - of - view angle of wide to determine whether to use the wide lens.

[0079] As Figure 4BAs shown, when the first shooting lens is wide, it is necessary to determine whether the first focusing distance is greater than the minimum focusing distance of tele. If it is, the second shooting lens is tele when the target object is within the field of view of tele. If it is not, there are two cases. When the first focusing distance is between wide and tele, the lens that takes the clearest picture is the first shooting lens wide. When the first focusing distance is between ultrawide and wide, the lens that takes the clearest picture is ultrawide. Since the field of view of ultrawide is larger than that of wide, the field of view of ultrawide must meet the condition of including the target object. Therefore, it is not necessary to determine whether the target object is within the field of view, and ultrawide can be directly selected as the second shooting lens.

[0080] like Figure 4C As shown in the figure, when the first shooting lens is tele, since tele has the smallest field of view, the target object must be within the field of view of other lenses. If the first focus distance is greater than tele, the lens that takes the clearest picture is the first shooting lens tele; when the first focus distance is between wide and tele, the second shooting lens is wide; when the first focus distance is between ultrawide and wide, the second shooting lens is ultrawide.

[0081] In some embodiments, the method also includes: determining a first coordinate position of the target object in the image corresponding to the first camera lens; determining a second coordinate position of the target object under the second camera lens based on the first coordinate position and a coordinate mapping relationship between the first camera lens and the second camera lens; photographing the target object through the second camera lens to generate a first image includes: completing focusing on the target object through the second camera lens according to the second coordinate position, and generating the first image.

[0082] Regardless of whether the user performs shooting under the first shooting lens, after recognizing the target object, the first shooting lens will determine the first coordinate position of the target object in the previewed shooting image.

[0083] Since different cameras have different installation positions and pixels, the center point of the camera lens may be offset and the coordinate system size is different. Therefore, after determining the first coordinate position, the second coordinate position of the target object under the second camera lens can be determined according to the coordinate mapping relationship.

[0084] By determining the second coordinate position, when the second shooting lens is used for shooting, the second shooting lens can focus on the target object more quickly.

[0085] In some embodiments, the second coordinate position of the target object under the second shooting lens is determined according to the first coordinate position and a coordinate mapping relationship between the first shooting lens and the second shooting lens.

[0086] For example, when the target object is a human face, the first coordinate position of the human face may be multiplied by the coordinate system ratio of the first shooting lens and the second shooting lens, and then added with the center point offset value under the two lenses to determine the second coordinate position.

[0087] In some embodiments, the method further includes: before determining a first focus distance corresponding to the target object, in response to a received shooting instruction, photographing through the first shooting lens and generating the second image; or, after photographing the target object through the second shooting lens to generate the first image, in response to a received shooting instruction, photographing through the first shooting lens and generating the second image.

[0088] That is, the shooting method of the present disclosure may have two execution stages.

[0089] In some embodiments, after the user issues a shooting command, the first shooting lens can shoot and generate a second image, and at this time, the method is executed to obtain the first image of the target object by the second shooting lens, and the final output image is obtained through image synthesis technology. In this way, after the shooting command is issued, the delay of outputting the image is high, but the power consumption of the terminal is low.

[0090] In other embodiments, when the user selects the first shooting lens and frames the area containing the target object, the second shooting lens can be used to shoot the first image and perform image synthesis in real time. That is, before the user issues a shooting command, the terminal performs image synthesis in real time based on the preview image of the first shooting lens. After the shooting command is issued, this method can obtain the final image at a faster speed, but because the terminal performs image synthesis in real time, the power consumption is relatively large.

[0091] In some embodiments, the target object includes a face, and determining a first focus distance between the target object and a first shooting lens currently in use includes: using a face detection algorithm under the first shooting lens to determine the target object and determine the first focus distance.

[0092] In some embodiments, after the user issues a shooting command, a local fusion algorithm may be used to fuse the image of the target object captured by the second camera lens with the second image captured by the first camera lens, wherein the area of ​​the target object in the first image is replaced with the position of the target object in the second image.
