Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.

The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the steps.

In addition, all of the following terms "first" and "second" are used for distinguishing purposes only and should not be construed as limiting the present disclosure.

Referring to fig. 1, when the finder frame contains a flying bee and a flower at the same time, the user may shoot the flying bee or want to shoot a stationary flower. Taking focusing as an example, due to the hardware characteristics, the depth of field of the camera is limited, the focusing area is clear, and the virtual focusing area is blurred or blurred. The position of a moving object changes quickly, the moving object can be clearly shot only by short exposure (but the noise is more), and a static object can be exposed for a longer time, so that the definition and the noise are both considered. In the graph a in fig. 1, the photographed bees are clearer when the exposure time is shorter. In fig. 1, in panel B, there may be a partial loss of image detail when the exposure time is short. Because the images cannot be shot distinctively and pertinently, the shot images have the problems of detail loss or image unclear caused by improper shooting parameters, the image quality is low, and the shooting effect is poor.

Fig. 4 schematically shows a flowchart of a photographing control method according to an exemplary embodiment of the present disclosure, which may be applied to a capturing end in an image processing process, for example, in an image capturing process of capturing an image, capturing a video, or previewing an image. Referring to fig. 4, the photographing control method may include steps S410 to S440, with the terminal as an execution subject, described in detail as follows:

in step S410, if a trigger operation is detected, matching the trigger operation with a preset trigger operation; and the preset trigger operation corresponds to a photographing operation mode.

In the embodiment of the present disclosure, the trigger operation refers to an operation for triggering selection of a target area. The triggering operation may be performed by a user, and the processor of the terminal may acquire and detect whether the triggering operation of the user is received. The triggering operation may be various types of operations for selecting an area, for example, one or a combination of multiple types of operations may be click, button, voice, expression, and body motion, and is not particularly limited herein as long as the terminal can be triggered to select a target area.

When a trigger operation is detected, the trigger operation may be matched with a stored preset trigger operation. The preset triggering operation is stored in the terminal in advance and used for accurately triggering the operation of selecting the target area. The preset trigger operation may be determined according to the photographing operation mode of the terminal, that is, if the photographing operation mode is different, the corresponding preset trigger operation may be different. The photographing operation mode refers to a mode for performing a photographing operation. One terminal can comprise one or more photographing operation modes, and can be set according to actual requirements. Specifically, the photographing operation mode may be a non-contact view-and-frame photographing mode or a contact view-and-frame photographing mode. The contact viewfinder type photographing refers to a mode of photographing by contacting a viewfinder frame in a photographing interface, for example, clicking a photographing button on the photographing interface. The non-contact framing frame-type photographing refers to a mode of photographing without a contact photographing interface, such as a mode of clicking a key of a terminal, gesture photographing, voice photographing, expression photographing or photographing through an external device (such as an earphone and a selfie stick) connected with the terminal. In the embodiment of the present disclosure, a non-contact framing frame-type photographing is taken as an example of a key photographing mode.

Further, different preset trigger modes can be set based on the photographing operation mode of the terminal. The preset triggering mode in the embodiment of the present disclosure may include, but is not limited to, one or a combination of more than one of a key pressing mode, a clicking mode, and a touch trajectory mode. For the touch trajectory approach, different target areas may be represented by different touch trajectories. For example, the first touch trajectory may be used to represent the target area as a motion state, and the second touch trajectory may be used to represent the target area as a rest state. The first touch track is a u-shaped track, and the second touch track is an n-shaped track.

The preset triggering operation can be configured in two ways, and a flow chart of the preset triggering operation is schematically shown in fig. 5, and referring to the flow chart shown in fig. 5, the preset triggering operation mainly includes the following steps:

in step S510, it is determined whether the photographing operation mode is non-contact framing frame photographing; if yes, go to step S520; if not, go to step S530.

In step S520, in response to a first touch operation, determining a candidate region according to a region corresponding to a touch point of the first touch operation;

in step S521, in response to a second touch operation, the target area is determined from the candidate area according to an operation type of the second touch operation.

The first touch operation and the second touch operation are different in acting object, the first touch operation refers to clicking operation on a photographing interface, and the second touch operation refers to pressing operation on a key. After the first touch operation is detected, the area within the preset range may be used as a candidate area with the touch point of the first touch operation as the center. The preset range can be set according to actual requirements. For the second touch operation, different operation types may correspond to different target areas. For example, the second touch operation is a single key press, and the target area is a static area; the second touch operation is to press the key for multiple times, and the target area is an area in a motion state. Whether the target area is an area in a moving state or an area in a stationary state may also be distinguished by how heavy the key is pressed or how long it is pressed. That is, if the photographing operation mode is an operation such as a button without touching the finder frame, it is necessary to click the rough target region and then confirm that the target region is a still or moving region by an operation such as a subsequent button.

In step S530, in response to a first touch operation, the target area is determined according to a position of a touch point of the first touch operation.

In this step, if the photographing operation mode does not belong to non-contact framing frame photographing, that is, when contact framing frame photographing is performed, the first touch operation refers to a click operation on a photographing interface. The target area may be determined according to a position of a touch point of the first touch operation when the first touch operation is detected. Specifically, the area within the preset range may be taken as the target area with the touch point of the first touch operation as the center. The preset range can be set according to actual requirements. Specifically, the target area may be determined according to a state of the object to be photographed at the position of the touch point of the first touch operation. For example, if the position of the touch point of the first touch operation is the object in the motion state, the target area is the area in the motion state; the position of the touch point of the first touch operation is a stationary object, and the target area is a moving area.

It should be noted that, because each terminal has multiple photographing operation modes, the two preset trigger operations may exist simultaneously. In the embodiment of the disclosure, the preset trigger operation is configured for different photographing operation modes, so that the proper preset trigger operation can be configured for different photographing operation modes, and the effectiveness and pertinence of triggering are improved.

After the preset trigger operation is configured, when the starting operation is detected, the tracks or the form content of the two can be matched. For example, the operations or trajectories of the two may be compared to determine whether they are identical. If the two are the same, the matching is determined to be successful, and if the two are not the same, the matching is failed.

In step S420, if the matching is successful, a target area is determined from the to-be-photographed areas including the plurality of to-be-photographed objects in response to the trigger operation.

In the embodiment of the present disclosure, if the trigger operation and the preset trigger operation are successfully matched, a target area may be selected from areas to be photographed including a plurality of objects to be photographed according to the preset trigger operation corresponding to the trigger operation, and the specific selection manner may be as in step S510 to step S530 in fig. 5, which is not described herein again. The region to be photographed may be a region in the finder frame, in which a plurality of objects to be photographed may be included, and states of the plurality of objects to be photographed may be the same or different. The area to be shot corresponding to one view frame can comprise a plurality of objects to be shot in a static state and/or a plurality of objects to be shot in a moving state.

Specifically, when the camera is opened, the action of the user is monitored in real time, and if the trigger operation is detected to be consistent with any preset trigger operation, the target area is triggered and selected according to a mode corresponding to the trigger operation. And when the action is consistent with the preset action, triggering. For example, when the photographing operation mode is non-contact framing frame photographing, if the triggering operation is clicking a photographing interface and pressing a key for multiple times, the target area is an area in a motion state.

Through the triggering operation in the embodiment of the disclosure, a target area in a static state or a motion state can be selected from the areas to be shot including a plurality of objects to be shot, so that the accuracy and pertinence of the selection of the target area can be improved, and the problem of wrong selection of a shooting subject is avoided.

In step S430, obtaining a motion state type of the target area, and determining a target object from the target area; wherein the motion state type is a static state or a motion state.

In the embodiment of the present disclosure, after the target area is determined, the motion state type thereof, that is, whether the area where the object to be photographed by the user is located belongs to the still state or the motion state, may be acquired. After determining the motion state type of the target area, the target object may be determined from the target area. Since the target area is used to describe the type of the object to be photographed, and there may be a plurality of objects to be photographed belonging to one type, the target object to be finally photographed is selected from the target area.

Fig. 6 schematically shows a flow chart of determining a target object, and referring to fig. 6, the method mainly includes the following steps:

in step S610, it is determined whether the motion state type of the target area is a stationary state; if yes, go to step S620; if not, go to step S630.

In step S620, if the target area is in a stationary state, the touch point of the first touch operation is closest, and the object to be photographed in the stationary state is determined as the target object.

In this step, when the target area to be photographed is a static area, the target area may be selected through the first touch operation and the second touch operation or the first touch operation due to the difference of the photographing operation modes. Based on this, the target object can be selected from the target area according to the touch point of the operation of contacting the photographing interface. The target object may be selected according to a distance to the touch point. Specifically, the touch point of the first touch operation may be closest, and the object to be photographed in the stationary state may be determined as the target object. For example, referring to fig. 7, the object to be photographed in the still state includes an object a and an object B, and if the object a is closest to the touch point C of the first touch operation, the target object is the object a.

In step S630, if the target area is in a motion state, the object to be photographed in the target area is screened, so as to obtain the target object from the target area.

In this step, when the target area to be photographed is an area in a motion state, the target area may be selected through the first touch operation and the second touch operation or the first touch operation due to a difference in photographing operation modes. Based on this, the target object can be selected from the target area according to the touch point of the operation of contacting the photographing interface.

Specifically, it may be determined first whether or not there is a subject to be photographed in a moving state in the target region. Whether the target area is in motion can be determined, for example, by whether the positions of all the objects to be photographed in the target area are changed or other parameters.

And if the object to be shot in the motion state exists, the touch point of the first touch operation is closest, and the object to be shot in the motion state is determined as the target object. In the case where there is a motion state, a target object may be selected from the target area according to a touch point of an operation of contacting the photographing interface. The target object may be selected according to a distance to the touch point. Specifically, the touch point of the first touch operation may be closest, and the object to be photographed in the motion state may be determined as the target object. For example, referring to fig. 8, the object to be photographed in the motion state includes an object D and an object E, and if the object E is closest to the touch point C of the first touch operation, the target object is the object E.

And if the object to be shot in the motion state does not exist, providing prompt information on the shooting interface for reminding the user to select again.

It is added that after the target object is determined, a prompt mark may be provided at a preset position of the target object, so as to remind the user of the selected target object to be photographed.

Continuing to refer to fig. 4, in step S440, determining a photographing parameter for the target object in the target area according to the motion state type of the target area, and photographing the target object by using the photographing parameter to obtain a photographed image.

In the embodiment of the present disclosure, after determining the motion state type of the target area and the target object, in order to avoid the problem of poor image quality caused by using the same photographing parameter for photographing, the photographing parameter may be automatically adjusted according to the motion state type of the target area, so as to obtain the photographing parameter matched with the motion state type.

The photographing parameters may include one or more of a focusing parameter and an exposure time, and may include other types of parameters, which are not limited herein. The focusing parameters refer to parameters for changing the relative position of the object distance and the distance through the functions of a camera and a lens so as to enable a shot object to be blurred and clear. The exposure time refers to the light-sensitive time of the film, and the longer the exposure time, the brighter and the darker the picture produced on the film. The shorter the exposure time is, the moving object can be obtained; the longer the exposure time, the entire motion trajectory of the moving object can be acquired, and thus the obtained moving object is blurred.

For the target area and the target object whose motion state type is the stationary state, the automatic parameter may be set as the photographing parameter. The automatic parameters may be, for example, standard parameters that are not adjusted or default parameters. For example, a default focusing parameter and a default exposure time may be used as photographing parameters for a target subject in a stationary state.

For the target area and the target object whose motion state type is the stationary state, the default parameters have not been able to satisfy the photographing requirement, and thus the photographing parameters may be determined based on the motion parameters of the target object contained in the target area. When the photographing parameter is a focusing parameter, the motion parameter may be a distance of the target object relative to the terminal. Wherein the distance may be positively correlated with focus. That is, the smaller the distance, the smaller the relative position of focus; the greater the distance, the greater the relative position of focus. When the photographing parameter is the exposure time, the default exposure time can be shortened to obtain the corresponding exposure time, so that a clear target object is obtained. Specifically, the target exposure time may be set to the shortest exposure time first. Next, the moving speed of the target object may be judged, and the longest exposure time may be determined. The moving speed can be used as a reference, and the distance of the target object moving in the longest exposure time is smaller than a preset threshold value according to the moving speed, so that the longest exposure time is determined. The preset threshold value can be any value which enables an image to be clear, and can be specifically set according to actual requirements. After the longest exposure time is obtained, the longest exposure time may be taken as an exposure time of the target object in a moving state, and the longest exposure time may be smaller than a default exposure time. Of course, the shortest exposure time may also be directly set as the exposure time of the target object in the moving state.

In the embodiment of the disclosure, the automatic parameters are determined for the target object in the static target area, the photographing parameters are determined for the target object in the moving target area, different photographing parameters can be respectively determined based on different moving state types, the process of dynamically adjusting the photographing parameters according to the moving state type of the target area is realized, the photographing parameters can be accurately determined, the pertinence and the accuracy are improved, the limitation that only the same photographing parameters can be adopted is avoided, and the intelligent adjustment is realized.

After the photographing parameters of the target object are obtained, when a photographing triggering operation is received, the photographing parameters are adopted to photograph the target object, so that a photographed image containing the target object is obtained. The photographing triggering operation may be a voice operation, or an operation of clicking a photographing control or pressing a volume button, and the like. The photographed image may be a clear still image containing a target object in a moving state or a target object in a still state.

According to the technical scheme, the novel operation mode is provided, a user can select a subject (namely a target subject) to be shot in a region to be shot comprising a plurality of subjects to be shot through trigger operation, and the problems that the camera recognizes the subject incorrectly, so that errors such as focusing, exposure and white balance are caused, the shooting parameters are not appropriate, and the quality of a shot image is low are solved. The distinguishing of moving and static objects to be shot can be realized through new gestures such as trigger operation. And the photographing parameters aiming at the target object can be automatically adjusted according to different motion state types of the target object. For the moving target object, the exposure time is reduced, so that the photographed image corresponding to the moving target object is clear, and the image quality is improved. The problem that the target object in a static state loses partial details due to too short exposure time is avoided, and the integrity and the image quality can be improved. Different target areas are selected through trigger operations corresponding to different photographing operation modes, and appropriate photographing parameters are determined according to the motion characteristics (motion state types) of the target areas to carry out photographing control. The limitation caused by the fact that the objects to be photographed in all states can only be photographed according to the same photographing parameters in the related art is avoided, so that the photographing parameters are more consistent with the target area, the matching degree and the accuracy are improved, and the photographing quality and the photographing effect are also improved.

Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
