In this way, since the direction prompt information is displayed on the electronic device, the electronic device can move according to the direction prompt information, and thus, the time consumed for re-controlling the target object to appear in the visual angle of the lens can be reduced.
Referring to fig. 2, fig. 2 is a flowchart of another display method provided by the embodiment of the invention. The main differences between this embodiment and the previous embodiment are: the target object needs to be selected before the first image data is acquired by the second device. As shown in fig. 2, the method comprises the following steps:
step 201, acquiring a second preview image through the first device, and displaying the second preview image on the electronic device.
The second preview image may include a target object, and certainly, the second preview image may further include other background objects.
Optionally, the electronic device includes a main camera and an auxiliary camera on the same surface, the first device is the main camera, and the second device is the auxiliary camera; alternatively, the first and second electrodes may be,
the electronic equipment comprises a camera assembly, the camera assembly comprises a first camera and an image sensor, the first device is the first camera, and the second device is the image sensor.
Wherein, main camera and vice camera can all be located electronic equipment's same surface, for example: on the back plate of the electronic equipment, preferably, the main camera and the auxiliary camera can also be arranged on the same straight line. In addition, it should be noted that the viewing angle of the sub camera may be greater than or equal to the viewing angle of the main camera.
The camera assembly can comprise a first camera and an image sensor, and the visual angle of the image sensor can be larger than or equal to that of the first camera. For example: as an optional implementation, the first image data acquired by the image sensor for a certain object may include content larger than that included in the first preview image acquired by the first camera for the certain object: the first image data acquired by the image sensor may include a target object and a first background object, and the first preview image acquired by the first camera may include only a part of content in the first background object. It should be noted that the first camera may be a camera that does not support optical zooming.
In the embodiment of the present invention, the types of the second devices may be different, for example, the second devices may be sub-cameras or image sensors, so that due to the different types of the second devices, flexibility of acquiring the first image data through the second devices is increased.
Step 202, when an input operation for the second preview image is received, detecting whether the target object in the second preview image can be tracked according to an object tracking technology. In case the target object cannot be tracked, performing step 203; returning to execute the step 202 when the input information of the target object tracking error is received; in case the target object can be tracked, step 204 is performed.
Among them, the Object Tracking (OT) technique may be: in the image shooting process, a certain object is tracked and marked out in real time through a preset frame body in the image. Common object tracking techniques include face tracking. For example: a user can click a certain position of an image in the image shooting process, and the object tracking technology can identify an object corresponding to the position according to the position of the image clicked by the user, expand the object to the edge of the object, and draw a corresponding preset frame (such as a rectangular frame) according to the edge of the object. The face tracking can identify the position of the face in the image when the image is shot, and draw a rectangular frame corresponding to the face according to an object tracking technology.
When an input operation aiming at the second preview image is received, detecting whether a corresponding target object at the position determined by the input operation can be tracked or not by combining an object tracking technology according to the position determined by the input operation in the second preview image. For example: and determining the target position through input operation, and detecting whether the contour of the target object can be tracked by taking the target position as a center and expanding outwards through combining an object tracking technology. The outline of the target object may be a rectangular box type or a circular box, etc.
When the determined target object is wrong, the process may return to step 202, so that the target object may be re-determined according to the input operation of the user.
And step 203, displaying prompt information for prompting that the user cannot track the target object.
The content of the prompt message may be a text message, and the text message may be "the target object cannot be tracked"; of course, the content of the prompt message may also be image information, and the image information may include the content of "the target object cannot be tracked".
Note that the type of the prompt information is not limited herein. In addition, step 203 is an optional step.
Therefore, when the prompt information is displayed, the user can acquire the tracking state of the target object in time, and can make corresponding reaction according to the prompt information, so that the user experience is improved.
And 204, acquiring a first preview image through the first device under the condition that the target object can be tracked. Detecting whether the first preview image comprises a target object or not; if the first preview image does not include the target object, go to step 205.
The specific scene of the target object, which is not included in the first preview image acquired by the first device of the electronic device, may include the following scenes: first, the preview image obtained by the first device includes the target object, but after the focal length of the first device is adjusted, the first preview image obtained by the first device does not include the target object, and the electronic device may specifically adjust the focal length of the first device according to an instruction input by a user. And the particular type of instruction is not limited herein. For example: the instruction may be a voice instruction, and of course, the instruction may also be a touch operation, such as a single-finger operation or a double-finger operation.
In addition, the specific scene of the target object, which is not included in the first preview image acquired by the first device of the electronic device, may further include the following scenes: the target object is included in the preview image first acquired by the first device, but after the electronic device is moved, the target object is not included in the first preview image acquired by the first device.
Step 205, acquiring first image data through a second device of the electronic device, wherein the first image data includes the target object.
For specific expressions of the second device and the first image data, reference may be made to corresponding expressions in the previous embodiments, and details are not described herein again.
Step 206, identifying the position of the target object in the first image data.
Wherein the position of the target object in the first image data may be identified by object tracking techniques, such as: the first image data may be in the form of a rectangular image, and the target object may be at an upper left corner, an upper right corner, a lower left corner, a lower right corner, or a middle position of the rectangular image.
Step 207, displaying direction prompt information according to the position relation between the position of the target object in the first image data and a preset position, wherein the direction prompt information is used for prompting a user to move the electronic device, so that a preview image acquired through the first device after movement includes the target object.
The specific representation of the preset position and the direction prompt information may refer to the corresponding representation in the previous embodiment, which is not described herein again.
Optionally, after displaying the direction prompt information according to the position relationship between the position of the target object in the first image data and the preset position, the method further includes:
acquiring second image data in real time through the second device in the moving process or after the electronic equipment moves;
taking an image by the first device if the position of the target object in the second image data at least partially coincides with the preset position.
Wherein the focal length (which may also be referred to as the viewing angle) of the second device is unchanged before and after the user moves the electronic device in the cued direction.
The first device can also acquire the preview image in real time, and when the user moves the electronic device according to the prompting direction and the target object appears in the preview image acquired by the first device, the prompting information does not need to be displayed any more.
If the user does not move the electronic device according to the prompting direction, and thus the second image data obtained in real time through the second device does not include the target object, prompting text information such as that the object completely deviates, the direction of the electronic device is required to be readjusted, or that the object completely deviates and the lens direction of the electronic device is required to be readjusted can be displayed on the electronic device. If the user moves the electronic device again, and the second image data obtained in real time through the second device includes the target object, the prompt direction may be displayed again.
In addition, in the case where the position of the target object in the second image data at least partially coincides with the preset position, for example: the preset position can be in the shape of a rectangular frame or a circular frame, when the preset position is at least partially overlapped with the position of the target object in the second image data, the target object can be determined to move to the preset position, and the electronic device can shoot the image through the first device at the moment because the imaging effect of the target object at the preset position is generally good.
It should be noted that, when the first device acquires the first preview image again after the image is shot by the first device, the contour and the position of the target object can be tracked continuously according to the object tracking technology, so that the subsequent electronic device can complete continuous shooting for the target object conveniently.
In the embodiment of the invention, the electronic equipment can move according to the direction prompt information, so that the moving efficiency of the electronic equipment is improved; and when the target object moves to the preset position, the image can be shot through the first device, the effect of the shot image is better, and therefore the imaging effect of the shot image is improved.
Optionally, the preset position is a central position of the first image data or the second image data.
In an optional implementation manner, if the first device is a main camera and the second device is a sub-camera, when the first device and the second device acquire image data for the same object, the content included in the middle position of the image data acquired by the second device for the object may be the same as the content included in the image data acquired by the first device for the object.
In another optional implementation, if the first device is a first camera and the second device is an image sensor, after the focal length of the first device is adjusted, and when image data is acquired for the same object by the first device and the second device, the content included in the image acquired by the first device may be the same as the content included in the middle position of the image data acquired by the second device; it can also be understood that: the content included in the image acquired by the first device may be a content included in a middle position of the image data acquired by the second device and amplified by an "interpolation method".
In the embodiment of the invention, the preset position is the central position of the first image data or the second image data, so that the target object moves to the central position to finish image shooting through the first device, and the imaging effect of the image is further improved.
In the embodiment of the invention, the target object can be determined firstly through the steps 201 to 207, so that the position of the target object can be identified more conveniently and quickly in the first image data subsequently, and the determination speed of the prompt direction is further correspondingly improved.
