Detailed Description

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

An exemplary embodiment of the present disclosure provides an image capturing method, which can complete capturing of a specific target object in a scene with poor light and a specific captured object, and this embodiment is described by taking a scene such as a museum or an exhibition hall as an example.

Different from a common photographing scene, the light in the museum environment is dark as a whole, and the light sources are multiple and concentrated locally. In addition, the shot objects are mostly placed in the glass showcase, and the glass showcase has the defects of light reflection, different sizes of the objects and delicate details. In addition, the shooting distance and the number of objects entering the scene are not controllable. In this scenario, a process of shooting by using the image shooting method provided by the embodiment of the present disclosure is shown in fig. 1, and includes:

step 101, under the condition that at least one local light source exists in the framing range, identifying a target object, and determining a shooting range according to the position of the target object.

In this step, when it is necessary to photograph a target object, the target object is recognized.

Optionally, in the embodiment of the present invention, a "target object shooting mode" is added to a camera application of a terminal such as a mobile phone. The mode can be started through user operation under the condition that at least one local light source exists in a view range, and the mode can also be started in the scenes such as a museum and the like after the camera application is started. Here, a local light source is a light source for achieving local illumination for a specific range in a scene.

According to the position of the target object obtained by identification, the shooting range can be further determined, and a specific flow is shown in fig. 2 and includes:

step 201, detecting a target object with a complete contour in the current shooting range as a first target object, and detecting a target object with an incomplete contour in the current shooting range as a second target object.

When the camera is opened, a shooting range, namely a view range in a view frame displayed on a mobile phone screen, is selected according to the default configuration of the camera. In the case where there are a plurality of subjects, there is a possibility that a part of the subjects is not completely received in the finder frame. Namely, in the shooting range, target objects with complete outlines and incomplete outlines exist. In this step, for this phenomenon, first, a first target object with a complete contour and a second target object with an incomplete contour are identified within a default shooting range.

Step 202, adjusting the shooting range to include all the first target objects and exclude the second target objects.

In this step, in order to ensure the purity of the picture and to improve the final shooting effect, the shooting range is adjusted according to the result identified in step 201, so as to include all the first target objects and exclude the second target objects, that is, exclude target objects with incomplete outlines.

For example, in a museum collection shooting scene, the shooting distance is not controllable, and generally cannot be too close to the shot object, so that the automatically selected framing range when the shooting application is started is not the shooting range required by the user. The field angle range needs to be automatically changed, and the image needs to be enlarged and reduced in real time. When a plurality of complete collection are shot, the camera lens can be pulled far to cover all the collection, or can be properly pulled close to eliminate incomplete collection at the edge; however, due to the reasons of interest, distance or crowding of the user, when only one complete collection appears in the shooting range, the lens of the mobile phone can be automatically shortened so as to remove the incomplete collection.

Illustratively, the step of adjusting the shooting range includes at least any one or more of the following operations:

adjusting the size of a shooting range;

adjusting the resolution of the shooting range;

and adjusting the focal length of the shooting range.

It should be noted that the operations listed above for adjusting the shooting range are only exemplary partial contents. Those skilled in the art will appreciate that the means by which the adjustment of the shooting range can be achieved is not limited to those listed.

The above-mentioned operations of adjusting the shooting range can be used alone or in combination to achieve the best shooting effect. For example, the resolution is maximized when the size of the photographing range is reduced to obtain the clearest target object image.

And 102, shooting the image in the shooting range.

In this step, after the shooting range is selected, an image, such as a photograph or a movie, can be shot. The shooting action can be triggered by the user operating the screen or the entity key and can also be automatically carried out.

An exemplary embodiment of the present disclosure further provides an image capturing method, and with the use of the method, after an image is captured, a view including associated display information of the image is generated, so that information presentation is more complete and vivid, and user experience is improved. The specific process is shown in fig. 3, and includes:

and 301, acquiring the associated display information of the shot image.

The method comprises the following steps:

and acquiring the text description information of the image as the associated display information of the image.

The local part related to the local magnified picture can be automatically selected or can be selected through user operation.

The text description information can be generated locally, and the user can input the text description information by typing or voice and the like, and can also acquire the text description information by scanning an introduction text billboard beside the collection through a camera. The word description information may also be acquired remotely, for example, by searching or requesting a specific server to acquire associated word description information after identifying the photographic subject.

In the scenes of museums and the like, the local magnified picture can be a collection detail picture, and the text description information can be a collection introduction. In order to facilitate the association of the collection with the details and the collection introduction by the user, the imaging is performed again, the specific local details of the original collection are amplified to generate a detail picture, or the characters of the collection introduction are added below the picture (the characters can be used for shooting a billboard of the collection introduction through a mobile phone, and the characters are automatically scanned and then added to the corresponding area).

Step 302, generating a view containing the image and the associated display information.

In this step, a view is generated that simultaneously displays the image and the associated display information.

Fig. 4 is an example of a view including an image and a partially enlarged picture.

Fig. 5 is a view example, which includes an image and a text description information.

Fig. 6 is an example of a view including an image, a partially enlarged picture, and textual description information.

If the shot image is a section of film, when generating the view, the image part does not use the complete film, only part of the image part (the clip can be automatically generated, or the preview film of the film formed by marking partial sections by the user is added into the view) is added into the view in the original film format or compressed into other film formats. And after detecting the operations such as clicking and the like of the user, indexing the corresponding original film for playing and displaying.

Exemplary embodiments of the present disclosure also provide an image capturing method, after the image capturing is completed, the image is further processed in detail to obtain better imaging, and for example, any one or more of the following processes may be performed on the captured image:

In the processing of "removing part or all of the image information except the target object in the image", the center of the image is the target object, so the image information except the target object is unnecessary information, and the part or all of the image information can be removed as required to highlight the target object as much as possible, so that the useful information in the image is more clear.

In the museum scene of collecting a collection, an image recognition algorithm can be used to separate the target object from the background, and the face information in the photo is removed (for example, the face smaller than the picture 1/4 appearing in the photo is set as irrelevant information and removed), so that the picture is presented more cleanly. The surface light reflection area of the glass cabinet for storing the collection of the library can be identified, the reflected light is removed, and the image of the light reflection part is repaired to obtain a more complete target object image. The specific culling rule can be modified according to the use scene adaptability setting.

For the process of "adjusting the exposure degree to the target object according to the distance between the lens and the target object", for example, the distance between the brightest point in the photograph and the lens of the mobile phone may be measured for a state where the background environment is dark and the light source irradiating the target object is relatively concentrated. When the measured distance is short, short exposure is realized, and fuzzy texture details and noise points caused by high brightness of long exposure are reduced as much as possible; when the measured distance is longer, longer exposure is realized to increase brightness and prevent the picture from being too dark and losing details.

For the process of "acquiring the interesting range of the image, and encoding the interesting range and the part outside the interesting range respectively", for example, an interesting Range (ROI) may be set, and after the ROI is defined, the subsequent compression of the image is performed with a blocking process. Pixels in the ROI use lower quantization parameters during encoding, and further more high-frequency information is reserved; the rest part can be matched with higher quantization parameters according to the memory allocation and the image quality requirement, so that the memory occupation is reduced on the premise of ensuring the completeness of the key information of the picture.

For the process of remotely acquiring the supplementary information of the target object and modifying the target object according to the supplementary information, a remote database can be maintained, the supplementary information related to the target object is stored in the remote database, and after the target object is shot, the supplementary information is acquired from the remote database. For example, under museum collection shooting scene, to the condition that collection itself has the details to lose (promptly the historical relic can't be restoreed), the processing that obtains supplementary information improves interactive experience, adds collection repair function, utilizes techniques such as machine learning, according to the introduction of collection (such as material, color and luster) realization texture restoration and former face restoration, increases interest and interactive.
