Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In order to achieve a good image shooting/video recording effect without manual movement of the device by a user, and enable a target object to be located in the center of a picture as much as possible, the application discloses a processing method, a processing device and electronic equipment.
The method and apparatus may be applied to electronic devices with cameras (i.e., electronic devices disclosed herein), which may be, but are not limited to, devices in a wide variety of general or special purpose computing device environments or configurations, such as: personal computers, server computers, hand-held or portable devices, tablet devices, multiprocessor systems, and the like.
The processing procedure of the processing method disclosed in the application is shown in fig. 1, and specifically includes:
The acquired information sensed by the first camera is an image shot by the first camera or a recorded video image frame.
The electronic device invokes the first camera based on an image shooting instruction for indicating shooting an image or a video recording instruction for indicating recording a video, which are manually triggered by a user or automatically triggered by the device.
In this embodiment of the present application, when the first camera collects information (image/video image frame), the viewing angle range is greater than the viewing angle range matched with the output information (image/video image frame), and the resolution of the collected information sensed by the first camera is correspondingly greater than the target resolution of the output information limited by the output requirement.
Preferably, the first camera is a wide angle camera.
The target resolution of the output information limited by the output requirement is 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 a video file that the user has selected to be created, 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.
And responding to the image shooting instruction or the video recording instruction, the electronic equipment starts the first camera in a calling mode, and creates a first drawing area for real-time corresponding to the acquired information sensed by the first camera 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 drawing region is represented as a region Preview1 divided into five equally 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 outputting information correspondingly in real time.
The output information is an image which is imaged and output in an image shooting scene, or is a video image frame which is output to an encoder in a video recording scene to be encoded and stored to form a video file or is transmitted in real time (video frames are transmitted to opposite-end equipment in real time in video call/video conference).
In response to the image capturing instruction or the video recording instruction, the present embodiment creates a second drawing area for real-time corresponding output information based on the output requirement in addition to the 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 output information such as images/video image frames and the like limited by the output requirement, and the size of the second drawing area is correspondingly smaller than the size of the first drawing area because the target resolution limited by the output requirement is smaller than the resolution of acquired information (images or video image frames) of the first camera.
Referring to the example of fig. 3, the second drawing region is represented as a region Preview2 which is trisected in the height and width directions, and Preview1 corresponds to equal-sized bisectors in the same direction as Preview 2.
The target object is a subject to be photographed in a scene such as a photograph or video recording, for example, a person, an animal, or a scene, which is a subject to be photographed in focus. In implementation, the target object in the first drawing area may be identified according to the object feature of the object indicated by the user's specified operation (e.g., the person object marked in the photo preview or video preview by the user), or the electronic device may identify, as the target object, the key shooting object in the image or video image frame based on an algorithm.
In the video recording scene, preferably, a corresponding artificial intelligence (Artificial Intelligence, AI) algorithm can be utilized to identify in real time the target object with the corresponding object feature learned in advance in each video image frame acquired by the first camera. The object features may include, but are not limited to, facial features and/or skeletal features of objects such as humans or animals, and the like.
Preferably, the facial features include facial features corresponding to different facial expressions of an object such as a person or animal, and the skeletal features include skeletal features corresponding to different poses of the object such as a person or animal.
And then, further determining the corresponding position information of the target object in the first drawing area to obtain the target position. The target location may be, but is not limited to, a location represented by a pixel coordinate point.
And 105, 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 according to the target position and the second drawing area, wherein the target area and the second drawing area have the same size.
After determining the corresponding target position of the target object in the first drawing area, the step specifically determines a target area which comprises the target position and has the same size as the second drawing area from the first drawing area according to the target position and the second drawing area, and takes the target acquisition information corresponding to the determined target area as the acquisition information of the second drawing area.
Wherein the first drawing area includes a center area and an edge area.
In the present embodiment, the center area of the first drawing area is set as: the dot concentration corresponding to the first drawing region can include a region formed by the dots in the first drawing region, the region being centered on the dot and having a size equal to the size of the second drawing region.
Accordingly, the edge area of the first drawing area is set as: the first drawing area is an area other than the center area.
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 drawing area, determining the target area according to the edge principle.
Wherein, the target area is determined according to the center principle, which can be further realized as: and determining an area which takes the target position corresponding to the target object as a center and has the size of the second drawing area in the first drawing area as a target area.
For example, if the target position of the target object corresponding to the first drawing region is the center position O of the first drawing region, as shown in fig. 4 (a), the region area_1 having the target region centered on O and the same size as the second drawing region in the first drawing region may be determined based on the center principle, and if the target position of the target object corresponding to the first drawing region is the position a of the first drawing region, as compared with fig. 4 (b), the region area_2 having the target region centered on the position a and the same size as the second drawing region in the first drawing region may be determined as the target region. Similarly, fig. 4 (c) -4 (e) provide schematic diagrams corresponding to the determined target areas area_3, area_4, area_5 in the case where the target position is the position B, C, D in the first drawing area, respectively.
The process of determining the target area according to the edge principle can be further implemented as: 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 from the first drawing region as a target region.
Preferably, the above proximity condition is used to characterize that a distance between a center point of the region and the target position is a shortest distance among distances between center points of the candidate regions in the candidate region set and the target position; the candidate region is a region which has a size of the second drawing region in the first drawing region and contains the target position.
Taking a position P as an example of a target position corresponding to the target object in the first drawing region, a candidate region having a size equal to that of the second drawing region and including the position P is a region area_x and a region area_y, see fig. 5 (a) and 5 (b), respectively, wherein a distance between a center of the region area_x and the position P is smaller than a distance between a center of the region area_y and the position P, thereby determining the region area_x as the target region.
On the basis of determining the target area, collecting information corresponding to the target area (namely, target collecting information) is further used as collecting information of a second drawing area, and the collecting information of the second drawing area is used as output information when information is output.
In an embodiment, the acquired information sensed by the first camera is image information in a shooting scene, in this embodiment, an image corresponding to the target area (essentially, a part of the image acquired by the first camera) is taken as an image of the second drawing area, and accordingly, the image of the second drawing area can be output on a display screen interface of the device in real time (for a user to view the shot image), and the image is stored in the device.
In another embodiment, the acquired information sensed by the first camera is a video image frame in a video recording scene (such as a video acquisition scene, a video call/video conference scene, etc.), in this embodiment, a portion of the video image frame acquired by the first camera located in the target area is used as a video image frame of the second drawing area, and accordingly, the video image frame of the second drawing area obtained in the recording process can be output in real time on a display screen interface of the device (for a user to view in the recording process), and subsequent processing matched with 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-end device participating in the call/conference in real time, in the video file scene, the video image frame of the second drawing area is transmitted to a video encoder, and the video encoder performs encoding processing on the video image frame of the second drawing area to form a recorded video file, etc.
In practice, a portion located in the target area may be cut out from an image or video image frame corresponding to the first drawing area based on the image cutting means, as an image or video image frame of the second drawing area; alternatively, the portion of the image or video image frame corresponding to the first drawing region located at 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 wide-angle visual angle advantage of the wide-angle camera is fully utilized, the image or video image frame with the resolution larger than the target resolution limited by the output requirement is collected, the target position of the target object in the first drawing area corresponding to the first camera is used as the basis, the collected information of the target area containing the target position is selected from the first drawing area in a targeted manner according to the center principle or the edge principle to serve as the collected information of the second drawing area, the automatic adaptation of the target object to the center position of the second drawing area for outputting information correspondingly in real time or the position which is as close to the center as possible can be achieved, manual movement of equipment by a user is not needed, and camera shake caused by manual movement of equipment is correspondingly avoided.
According to the embodiment of the application, in a video recording scene, the electronic device can automatically complete image region cutting or information extraction on each video image frame taking a target object (such as a person object) as a center (or as much as possible) aiming at each video image frame acquired by the first camera, and along with continuous acquisition of the video image frames by the first camera, a following image region cutting/extraction effect taking the target object as a center (or as much as possible) is formed, so that the target object in a video file obtained by recording or a series of video image frames transmitted in real time is always in the center of a picture (or as much as possible in the picture center), and because the wide-angle camera can cover a wider visual field, a photographer does not need to move the device in order to keep up with the movement of the shot target object (such as the person object), and video picture jitters caused by the mobile device are correspondingly avoided.
In an embodiment, referring to fig. 6 in combination, assuming that the width and the high resolution of the second drawing region are given and denoted as W2 and H2, respectively, and assuming that the proportionality coefficient Kw of the width-direction resolution of the first drawing region to the width-direction resolution of the second drawing region and the proportionality coefficient Kh of the height-direction resolution of the first drawing region to the height-direction resolution of the second drawing 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 high resolution of the first drawing region, respectively.
Taking the case that the resolution of the video image frame of the video file to be output when recording video is FHD (Full High Definition ) resolution, i.e., 1920 (W2) x 1080 (H2), and the proportionality coefficients Kw and Kh are both 5/3, then:
W1＝1920*5/3＝3200；
H1＝1080*5/3＝1800。
that is, the first camera, such as the wide-angle camera, is required to have a wide and high resolution of 3200 and 1800 as the original output resolution, so that the resolution of the video image frame of the recorded video is ensured to be correct, and the user's look and feel will not be blurred due to the processing of clipping and scaling the picture based on the first drawing region and the second drawing region.

Specifically, according to the corresponding ranging technology, the distance between the target object and the equipment plane of the equipment where the first camera is located can be detected, and the target distance is obtained.

The distance condition is a condition for representing that the distance between the object and the device plane of the device where the first camera is located is too close or too far to enable the first camera to clearly image the object. Specifically, but not limited to, the following are provided: 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 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 change of the distance between the target object and 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 clear imaging of the target object can be realized without manual zooming operation of a user, and meanwhile, camera shake and picture jumping feeling during manual zooming are avoided, so that the shooting effect is better.
