Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The method is limited by optical limitation, under the condition that the pixel size and the aperture are larger and larger, the depth of field of short-distance shooting is shorter, the image quality around a lens is more obviously reduced, and when a main camera shoots an image of a short-distance scene, the problems of inaccurate focusing and unclear shooting are often caused.

Therefore, the embodiment of the present disclosure provides a shooting scheme, which at least provides one shooting mode: and (4) a full-image clear shooting mode. The image without blurring effect can be shot in the full-image clear shooting mode. The method comprises the steps of obtaining depth-of-field information and distance information of a scene to be shot, and judging whether the scene to be shot is a close-range plane shooting scene according to the depth-of-field information and the distance information; and responding to the planar shooting scene with the close distance to be shot, and switching to a full-image clear shooting mode to shoot so as to shoot a full-image clear image in the planar shooting scene. The method has the advantages that the shooting mode without blurring effect can be automatically selected for the screen shooting scene, the clear image of the whole image can be obtained in the plane scene, better shooting effect is achieved, and complicated operation steps caused by manual switching of a user are avoided.

The embodiments of the present disclosure will be described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is a flowchart illustrating a photographing method according to an exemplary embodiment of the present disclosure, provided with a full-view clear photographing mode for photographing an image without blurring effect, the method including the steps of:

in step 102, obtaining depth information and distance information of a scene to be shot, wherein the depth information comprises a distance between at least one shot object and another shot object;

in step 104, judging whether the scene to be shot is a close-range plane shooting scene according to the depth information and the distance information;

in step 106, in response to that the scene to be shot is a close-range plane shooting scene, switching to the full-image clear shooting mode for shooting.

The shooting method provided by the embodiment can be implemented by software, or by a combination of software and hardware, or by hardware, and the related hardware can be composed of two or more physical entities, or can be composed of one physical entity. For example, the method of the embodiment can be applied to an intelligent terminal with shooting capability, and the intelligent terminal is at least provided with a full-image clear shooting mode for shooting images without blurring effect. The intelligent terminal may be a device such as a PC, a tablet computer, a notebook computer, and a desktop computer, or a portable device such as a smart phone, a smart camera, and a PDA (Personal Digital Assistant), or a wearable device such as a smart band and a smart watch.

In the embodiment of the present disclosure, at least one shooting mode is configured: and (4) a full-image clear shooting mode. The full-image-definition shooting mode is used for shooting a full-image-definition image, and particularly shooting an image without blurring effect in a close-range mode.

The inventor finds that in some scenes, the user may desire to take a picture with blurring effect, while in some scenes, the user may desire to take a clear picture, and the user can only manually select different cameras to achieve different shooting purposes, which obviously has low efficiency. To this end, in another embodiment, a depth of field shooting mode is also provided. The depth-of-field shooting mode is used for shooting a locally blurred image. Depth of Field (DoF) generally refers to an object distance range in which a camera lens can clearly image a scene to be photographed, an area within the object distance range is called in-focus, an area outside the object distance range is called out-of-focus, the in-focus is a clear image, and the out-of-focus can be a clear image or a blurred image according to the Depth of Field (or Depth of Field), for example: for deep depth of field, clear images can be formed in focus or out of focus; for shallow depth of field, a sharp image can be formed in focus and a blurred image can be formed out of focus.

It should be understood that other capture modes may also be provided, and need not be described herein.

Regarding the full-view clear photographing mode/depth-of-field photographing mode, in one example, a photographing mode corresponding to one camera or a plurality of cameras may be used, and for example, the depth-of-field photographing mode may be obtained in combination with two cameras. Further, a wide-angle camera (ultra wide) can be used to obtain a depth-of-field shooting mode in combination with a main camera (wide), and a main camera or a wide-angle camera can be used to obtain a full-image clear shooting mode in combination with the main camera. The main camera may also be referred to as a standard camera. The wide-angle lens is a photographic lens with a focal length shorter than that of a standard lens, a visual angle larger than that of the standard lens, a focal length longer than that of a fisheye lens and a visual angle smaller than that of the fisheye lens. The wide-angle lens is divided into two types, namely a normal wide-angle lens and an ultra wide-angle lens, and is not limited herein. For example, if the scene is a planar shooting scene in a text mode, a wide-angle lens effect or a wide-angle lens assisting a main shooting lens effect can be used for enhancing, and image fusion is performed; if the scene is a blurring scene (depth-of-field shooting scene), the wide-angle lens and the main shooting lens are combined, and the depth information is input to the image fusion module to achieve the main body prominent blurring effect. By means of the methods, the problem of difficult focusing can be solved and a clear image can be obtained by close-range shooting.

In another example, the full-view clear photographing mode and the depth-of-field photographing mode may be photographing modes corresponding to different cameras, for example, the full-view clear photographing mode is a photographing mode corresponding to a first camera, and the depth-of-field photographing mode is a photographing mode corresponding to a second camera. The first camera is a camera that can be used to capture a clear image of the entire image in a close-range shooting scene, in other words, a camera that can be used to capture an image without blurring effect in a close-range shooting scene. The second camera is a camera that can be used to capture a locally blurred image in a close-up capture scene. For example, the focal length of the first camera is smaller than the focal length of the second camera. Accordingly, when the photographing mode is switched, a lens may be switched. Specifically, the switching to the full-image clear shooting mode for shooting includes: switching to the first camera for shooting; the switching to the depth-of-field shooting mode for shooting includes: and switching to the second camera for shooting.

According to the embodiment, different cameras are adopted to shoot different scenes, and pertinence is achieved, so that the shooting effect is better. It should be understood that the full-view clear shooting mode may be one of the shooting modes of the first camera, and the first camera may also be configured with other shooting modes, and the second camera is the same, which is not repeated herein.

In one example, a wide-angle camera is configured in the terminal device, and the first camera may be the wide-angle camera. Further, a main camera is also configured in the terminal device, and the second camera may be the main camera. Accordingly, when the photographing mode is switched, a lens may be switched. Specifically, the switching to the full-image clear shooting mode for shooting includes: switching to a wide-angle camera for shooting; the switching to the depth-of-field shooting mode for shooting includes: and switching to the main camera for shooting.

This embodiment chooses more suitable camera lens to shoot for use to different scenes, reaches better shooting effect. When the image of a plane scene is shot, the problem of inaccurate focusing in close-range shooting can be solved, and a clear image can be obtained.

It should be understood that the first camera and the second camera may also be other cameras, as long as the first camera can shoot a clear picture of the whole image in a close-distance shooting scene, and the second camera can shoot a local blurred picture in a close-distance shooting scene, which is not repeated herein.

The scene to be photographed may be a scene corresponding to the finder frame. The short-distance plane shooting scene is a short-distance scene and a short-distance plane shooting scene; the short-distance three-dimensional shooting scene is a short-distance scene and is short for three-dimensional shooting scenes. The close-up scene is used to indicate that the shooting scene is currently at a close-up. For example, a close-range scene may be determined within a specified distance range based on distance information. The distance information may be a distance between the subject and a distance measuring module (e.g., a distance sensor) on the camera or the terminal. When the acquired distance information is within the specified distance range, the current short-distance scene can be judged, and when the acquired distance information is outside the specified distance range, the current short-distance scene can be judged not to be in. The specified distance range may be a range of the pre-configured object to be photographed and the camera/ranging module, and the range is small, so that the object to be photographed is characterized to be closer to the object to be photographed (the camera) within the specified distance range by using the distance information. The specified distance range can be configured according to requirements.

The embodiment of the disclosure can acquire the depth of field information and the distance information of the scene to be shot, and judge whether the scene to be shot is a close-range planar shooting scene or not according to the depth of field information and the distance information, and further judge whether the scene to be shot is a close-range stereoscopic shooting scene or not.

With respect to the depth information, the depth information may include at least one pitch. Any one object in the scene to be photographed can be taken as a photographed object. For example, an entity corresponding to any pixel point in the frame can be taken as a subject. The pitch is a distance between one subject and another subject. For example, one subject may be a near-point subject and the other subject may be a far-point subject. The near-point photographic subject may be a subject closer to the camera/ranging module among the photographic subjects (e.g., one of P photographic subjects closest to the camera/ranging module among all the photographic subjects), and the far-point photographic subject may be a subject farther from the camera/ranging module among the photographic subjects (e.g., one of Q photographic subjects farthest from the camera/ranging module among all the photographic subjects). By defining a pair of the photographic subject as a near point photographic subject and a far point photographic subject, scene determination accuracy can be improved. The depth of field information may include one or more pitches. The judgment of the planar scene or the three-dimensional scene is carried out through a plurality of intervals, and the judgment accuracy can be improved.

As to how to obtain the depth of field information, for example, the depth of field information may be determined by a Phase Detection Auto Focus (PDAF) technique, which is also called Phase Detection Auto Focus (PDAF), and the principle of the PDAF is to reserve some shielding pixel points on the photosensitive element, specially for Phase Detection, and determine the Focus offset value according to the distance between pixels and the variation thereof, so as to achieve accurate Focus. For this purpose, the phase focusing technique can be used to determine the distance between different objects to be photographed. And some terminals are also provided with distance sensors, the depth information can also be determined by the information collected by the distance sensors. The distance sensor may be a TOF (Time of flight) sensor or the like. So-called time-of-flight 3D imaging may be achieved by continuously sending light pulses to the target, and then receiving light returning from the object with a sensor, and finding the target distance by detecting the time of flight (round trip) of the light pulses. To this end, depth information may be determined from data collected by the distance sensor.

In order to be able to obtain a plurality of spacings, the distance sensor may also be an N × M distance sensor, so that a plurality of spacings are obtained. To improve the accuracy of the depth information, in one example, the depth information may also be determined in conjunction with the data collected by the distance sensor and the phase focus PDAF technique. For example, the depth of field information is determined by the data collected by the N × M distance sensor and the phase focus PDAF technique, thereby improving the accuracy of the depth of field information.

It should be understood that the depth information may also be obtained in other manners as long as the distance between different objects can be determined, which is not described herein again.

Regarding how the distance information is obtained, in one example, the distance information may be determined using a contrast diagonal CAF technique, while in some terminals, distance sensors are also provided, and the distance information may also be determined from information collected by the distance sensors. The distance sensor may be a TOF (Time of flight) sensor or the like. In order to improve the accuracy of the distance information, in one example, the depth of field information may also be determined by combining the data collected by the distance sensor and the contrast focus CAF technique, thereby improving the accuracy of the distance information.

The planar shooting scene may be an approximately planar scene, and the distance between different objects in the scene is within an allowable distance range, and the scene may be considered as the planar shooting scene. For example, scenes such as characters and pictures are often shot in a flat scene, and a user desires to shoot a clear image of the entire image. For example, the plane shooting scene is used for representing that the middle distance of the depth information is less than or equal to a preset distance threshold; specifically, the process of determining the planar shooting scene may include: comparing the acquired depth of field information with a preset distance threshold; and if the intermediate distance of the depth information is smaller than or equal to a preset distance threshold value, judging that the scene to be shot is a plane shooting scene.

In this embodiment, a scene to be photographed with a distance smaller than or equal to a preset distance threshold may be used as a plane photographing scene, so as to determine the plane photographing scene.

In some applications, it is desirable to shoot a clear text plan at a short distance, and for this reason, in one embodiment, the plane shooting scene is used to represent that the middle distance of the depth information is less than or equal to a preset distance threshold, and the scene to be shot is a text scene. For example, if the middle distance of the depth information is less than or equal to a preset distance threshold, determining that the scene to be shot is a planar shooting scene may include:

In the embodiment, the scene to be shot is limited to be a short-distance and plane scene, and the scene to be shot is also limited to be a character scene, so that a clear character plane graph of the whole graph is shot.

Regarding the stereoscopic shooting scene, the distance between different objects in the scene is not within the allowable distance range, and the scene can be considered as the stereoscopic shooting scene. For example, when a scene such as a doll or a petal is photographed, it is considered to be a stereoscopic photographing scene. When shooting a stereoscopic shooting scene at a short distance, the user is considered to be required to shoot an image with a blurring effect at that time, and for this reason, the shooting mode can be switched to a depth-of-field shooting mode for shooting. For example, the stereo shooting scene is used for representing that at least one distance in the depth information is larger than a preset distance threshold. For example, the process of determining the stereo shooting scene may include: comparing the acquired depth of field information with a preset distance threshold; and if at least one distance in the depth of field information is larger than a preset distance threshold value, judging that the scene to be shot is a three-dimensional shooting scene.

In this embodiment, a scene to be photographed with a distance greater than a preset distance threshold may be used as a stereo photographing scene, so as to determine the stereo photographing scene. In some examples, it may be further defined that when X distances are greater than a preset distance threshold, it is determined that the scene to be photographed is a stereoscopic photographing scene, and the X value is configured according to a requirement.

When shooting at a close distance, if a plane picture or a character plane is shot, the whole picture is expected to be clear, but if a stereo shooting scene such as a doll or a petal is shot, perfect blurring is also expected. The disclosed embodiment enables the terminal to intelligently address this problem.

The various technical features in the above embodiments can be arbitrarily combined, so long as there is no conflict or contradiction between the combinations of the features, but the combination is limited by the space and is not described one by one, and therefore, any combination of the various technical features in the above embodiments also belongs to the scope disclosed in the present specification.

One of the combinations is exemplified below.

As shown in fig. 2, fig. 2 is a flowchart illustrating another photographing method according to an exemplary embodiment of the present disclosure, provided with a wide-angle camera that can photograph an image without a blurring effect at a close distance and a main camera that can photograph a partially blurred image, the method including:

in step 202, obtaining depth information and distance information of a scene to be shot, wherein the depth information comprises a distance between at least one shot object and another shot object;

in step 204, it is determined that the scene to be shot is a close-range planar shooting scene or a close-range stereoscopic shooting scene according to the depth information and the distance information;

in step 206, in response to that the scene to be shot is a close-range plane shooting scene, switching to the wide-angle camera for shooting;

in step 208, in response to that the scene to be shot is a close-range stereoscopic shooting scene, switching to the main camera for shooting.

Fig. 2 is the same as the related art in fig. 1, and the details are not repeated here.

When the plane shooting scene and the three-dimensional shooting scene are faced, the wide-angle camera and the main camera are correspondingly selected for shooting, the clear image of the whole image can be obtained in the plane shooting scene, and the background blurring effect image is obtained in the three-dimensional shooting scene, so that the automatic camera switching is realized, the better shooting effect is achieved, and the complex operation of a user is reduced.

For example, for the shooting logic, depth of field information is added, and in combination with distance information, it can be determined whether the current scene is a stereoscopic shooting scene or a planar shooting scene. The method comprises the following steps that a scene such as a doll or a petal is shot in a three-dimensional shooting mode, at the moment, the shooting logic can select a main camera to shoot, and a good background blurring effect is obtained. If the scene is shot in a plane, such as shooting a plane character scene, the shooting logic can select a wide-angle lens to shoot, so that the characters of the whole picture are clearer.

While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present disclosure is not limited by the order of acts, as some steps may, in accordance with the present disclosure, occur in other orders and concurrently.
