Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to achieve a good image shooting/video recording effect without manually moving the device by a user and to enable a target object to be located in a picture center as much as possible, the application discloses a processing method, a processing device and electronic equipment.
The method and apparatus may be applied to an electronic device with a camera (i.e., the electronic device disclosed herein), which may be, but is not limited to, any of numerous general purpose or special purpose computing device environments or configurations, such as: personal computers, server computers, hand-held or portable devices, tablet-type devices, multi-processor appliances, and the like.
The processing procedure of the processing method disclosed by the application is shown in fig. 1, and specifically includes:
The acquisition information sensed by the first camera is an image shot by the first camera or a recorded video image frame.
The electronic equipment adjusts and starts the first camera based on an image shooting instruction used for indicating to shoot images or a video recording instruction used for indicating to record videos, wherein the image shooting instruction is triggered manually by a user or automatically by the equipment.
In the embodiment of the application, the visual angle range when the first camera collects information (image/video image frames) is larger than the visual angle range matched with the output information (image/video image frames), and the resolution of the collected information sensed by the first camera is correspondingly larger than the target resolution of the output information limited by the output requirement.
Preferably, the first camera is a wide-angle camera.
The output requirement is limited to the target resolution of the output information, i.e. the resolution required when outputting an image or video image frame. The target resolution may be, but is not limited to, the highest resolution of the display screen, or the resolution of the video file that the user chooses to create, or the resolution limited by real-time video transmission (e.g., real-time video transmission in a video call/video conference), depending on the particular use scenario.
Responding to an image shooting instruction or a video recording instruction, the electronic equipment starts the first camera, and creates a first drawing area used for corresponding to the acquired information sensed by the first camera in real time based on the started first camera. The size of the first rendering area matches the resolution of the acquired information (image or video image frame) sensed by the first camera.
Referring to the example of fig. 2, the first rendering region is represented as a region Preview1 divided into five equal parts in the height and width directions, respectively.
And 102, creating a second drawing area based on the output requirement, wherein the second drawing area is used for corresponding to the output information in real time.
The output information is an image which is imaged and output in an image shooting scene, or a video image frame which is output to an encoder in a video recording scene and is to be encoded and stored to form a video file or a video image frame which is to be transmitted in real time (a video image is transmitted to opposite-end equipment in a video call/video conference).
In response to an image capturing instruction or a video recording instruction, the present embodiment creates a second drawing area for corresponding output information in real time based on an output request, in addition to creating a first drawing area based on the first camera.
Specifically, the present embodiment creates the second drawing region based on the target resolution limited by the output requirement.
The size of the second drawing area is correspondingly matched with the target resolution of the output information such as the image/video image frame and the like limited by the output requirement, and the size of the second drawing area is correspondingly smaller than that of the first drawing area because the target resolution limited by the output requirement is smaller than the resolution of the acquisition information (image or video image frame) of the first camera.
Referring to the example of fig. 3, the second drawing region is represented as a region Preview2 trisected in the height and width directions, respectively, and Preview1 corresponds to a same-sized aliquot unit in the same direction as Preview 2.
And 103, analyzing the acquisition information of the first camera to obtain a target object included in the acquisition information.
The target object is a subject to be shot with emphasis in a scene such as a photograph or a video recording, and the subject to be shot with emphasis such as a person, an animal, or a scene is used as an image subject. In implementation, the target object in the first drawing area may be identified according to an object feature of an object indicated by a user's designated operation (e.g., a person object specified by the user in a photo preview or a video preview, etc.), or a key shooting object in an image or a video image frame may be identified as the target object by the electronic device based on an algorithm.
In the video recording scene, preferably, a target object having a pre-learned corresponding object feature in each video image frame captured by the first camera may be identified in real time by using a corresponding Artificial Intelligence (AI) algorithm. The object features may include, but are not limited to, facial features and/or skeletal features of a human or animal subject.
Preferably, the facial features include facial features corresponding to different facial expressions of a subject such as a person or an animal, and the skeletal features include skeletal features corresponding to different poses of the subject such as a person or an animal.
And step 104, determining a corresponding target position of the target object in the first drawing area.
And then, further determining the corresponding position information of the target object in the first drawing area to obtain the target position. The target position may be, but is not limited to, a position represented in pixel coordinate points.
And 105, according to the target position and the second drawing area, determining target acquisition information of a target area including the target position in the first drawing area as acquisition information of the second drawing area, wherein the target area and the second drawing area have the same size.
After the target position of the target object corresponding to the first drawing area is determined, a target area which comprises the target position and has the same size as the second drawing area is determined from the first drawing area according to the target position and the second drawing area, and target acquisition information corresponding to the determined target area is used as acquisition information of the second drawing area.
Wherein the first drawing region includes a center region and an edge region.
In this embodiment, the center area of the first drawing area is set to: the point set corresponding to the first rendering area may include an area formed by each point within the first rendering area, the area being centered on the self point and having a size equal to that of the second rendering area.
Accordingly, the edge area of the first drawing area is set to: a region other than the central region in the first drawing region.
When the target area is determined, if the target position of the target object belongs to the central area of the first drawing area, determining the target area according to a central principle; otherwise, if the target position belongs to the edge area of the first rendering area, the target area is determined according to the edge principle.
Wherein, the target area is determined according to the center principle, and can be further realized as follows: and determining an area which takes the target position corresponding to the target object as the center and has the size of the second drawing area as the target area.
For example, if the target position of the target object corresponding to the first drawing area is the center position O of the first drawing area, as shown in fig. 4(a), the target area may be determined as an area _1 centered on O and having the same size as the second drawing area in the first drawing area on the basis of the center principle, and referring to fig. 4(b), if the target position of the target object corresponding to the first drawing area is the position a of the first drawing area, the area _2 centered on a position a and having the same size as the second drawing area in the first drawing area may be determined as the target area. Similarly, fig. 4(c) -4 (e) respectively provide schematic diagrams of the corresponding determined target areas area _3, area _4, and area _5 in the case where the target position is the position B, C, D in the first drawing area.
The process of determining the target area according to the edge principle can be further implemented as follows: and determining a region which has the size of the second drawing region and contains the target position and the center point of which meets the approaching condition with the target position as a target region in the first drawing region.
Preferably, the above proximity condition is used to characterize that the distance between the center point of the region and the target position is the shortest distance among the distances between the center point of each candidate region and the target position in the candidate region set; the candidate region is a region of the first rendering region, which has a size equal to that of the second rendering region and includes the target position.
Taking a target position of the target object in the first rendering area as a position P, the candidate areas in the first rendering area having a size of the second rendering area and including the position P are an area _ x and an area _ y, respectively see fig. 5(a) and 5(b), where a distance between a center of the area _ x and the position P is smaller than a distance between a center of the area _ y and the position P, thereby determining the area _ x as the target area.
On the basis of determining the target area, further using the acquisition information corresponding to the target area (i.e., the target acquisition information) as the acquisition information of the second drawing area, where the acquisition information of the second drawing area is used as output information when the information is output.
In an embodiment, the acquisition information sensed by the first camera is image information in a photographed scene, and in the embodiment, an image corresponding to the target area (which is essentially a part of the image acquired by the first camera) is used as an image of the second drawing area, so that the image of the second drawing area (for a user to view the photographed image) can be output in real time on a display screen interface of the device, and the image is saved in the device.
In another embodiment, the captured information sensed by the first camera is a video image frame in a video recording scene (e.g., a video capture scene, a video call/video conference scene, etc.), in this embodiment, a portion of the video image frame captured by the first camera, which is located in a target area, is used as a video image frame of a second drawing area, and accordingly, the video image frame of the second drawing area obtained in the recording process (for a user to view in the recording process) can be output in real time on a display screen interface of the device, and a subsequent process matching the current scene is performed, for example, in the video call/video conference scene, the video image frame of the second drawing area is transmitted to an opposite device participating in the call/conference in real time, in the video file recording scene, the video image frame of the second drawing area is transmitted to a video encoder, and the video encoder performs an encoding process on the video image frame of the second drawing area, forming a recorded video file, etc.
In implementation, based on the image cutting means, a part located in the target area can be cut out from the image or video image frame corresponding to the first drawing area as an image or video image frame of the second drawing area; alternatively, a portion of the image or video image frame corresponding to the first drawing region, which is located in the target region, may be directly extracted as the image or video image frame of the second drawing region based on the information extraction technique without performing any clipping operation.
According to the method, the wide-angle camera is used as the first camera, the advantage of wide visual angle of the wide-angle camera is fully utilized, the image or video image frame with the resolution ratio larger than the target resolution ratio limited by the output requirement is acquired, the acquisition information of the target area containing the target position is selected from the first drawing area in a targeted mode according to a center principle or an edge principle and is used as the acquisition information of the second drawing area, the target object can be automatically adapted to the center position of the second drawing area used for corresponding output information in real time or the position as close to the center as possible, a user does not need to manually move the equipment, and accordingly camera shake caused by manual movement of the equipment is avoided.
Based on the embodiment of the application, in a video recording scene, the electronic device can automatically complete image region cropping or information extraction on each video image frame by taking a target object (such as a human object) as a center (or as far as possible) as the center, and form a follow-up image region cropping/extraction effect by taking the target object as the center (or as far as possible) along with continuous acquisition of the video image frames by the first camera, so that the target object in the recorded video file or a series of video image frames transmitted in real time is always in the center of the picture (or as far as possible in the center of the picture), moreover, because the wide-angle camera can cover a wider visual field, a photographer does not need to move the equipment for keeping up with the motion of a photographed target object (such as a person object), and accordingly video picture jitter caused by the mobile equipment is avoided.
In an embodiment, referring to fig. 6 in combination, assuming that the width and the high resolution of the second rendering region are given and are denoted as W2 and H2, respectively, and that the scaling factor Kw of the width direction resolution of the first rendering region and the width direction resolution of the second rendering region and the scaling factor Kh of the height direction resolution of the first rendering region and the height direction resolution of the second rendering region are given, the original output resolution of the first camera, such as the wide-angle camera, is required to be:
W1＝W2*Kw；
H1＝H2*Kh。
w1 and H1 represent the width and the high resolution of the first drawing region, respectively.
Taking the example that the resolution of the video image frame of the video file to be output when recording the video is FHD (Full High Definition), i.e. 1920(W2) × 1080(H2), and the scaling factors Kw and Kh are 5/3, then:
W1＝1920*5/3＝3200；
H1＝1080*5/3＝1800。
that is, the original output resolution of the first camera, such as a wide-angle camera, is required to be 3200,1800 wide and 1800 high, so as to ensure that the resolution of the video image frame of the recorded video is correct, and the user does not feel blurred due to the processes of cutting and zooming the picture based on the first drawing area and the second drawing area.
In an embodiment, referring to the flowchart of the processing method provided in fig. 7, the processing method disclosed in the present application may further include:
Specifically, the distance between the target object and the equipment plane of the equipment where the first camera is located can be detected according to a corresponding distance measurement technology, so that the target distance is obtained. The ranging technique may be, but is not limited to, Time of flight (TOF) and the like.
And step 702, if the target distance meets the distance condition, zooming the first camera according to the target distance.
The distance condition here is a condition for representing that the distance between the object and the device plane of the device in which the first camera is located is too close or too far, so that the first camera cannot clearly image the object. Specifically, but not limited to, the following settings are set: the distance between the object and the equipment plane of the equipment where the first camera is located is larger than a preset first threshold value, or smaller than a preset second threshold value, wherein the second threshold value is smaller than the first threshold value.
Under the condition that the target distance meets the distance condition, zooming processing is carried out on the first camera, the distance between the target object and the equipment plane is automatically judged based on the distance condition according to the distance change of the target object from the electronic equipment, and under the condition that the distance condition is judged to be met, the focal length of the first camera is adjusted to be a proper distance according to the distance between the target object and the equipment plane, so that the user is not required to manually execute zooming operation, clear imaging of the target object can be realized, meanwhile, hand trembling and picture jumping feeling during manual zooming are avoided, and the shooting effect is better.
