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 some, but not all, embodiments of the present application. 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.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The shooting method and apparatus, the electronic device, and the storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.
The embodiment of the application discloses a shooting method, which is shown in fig. 1 and comprises the following steps:
In this embodiment, the first image may be obtained by a front camera or a rear camera of the electronic device. For example, the first image may be a preview image obtained after the camera is turned on.
The preview image refers to an image that is displayed in the screen of the device but has not been photographed yet. Under a common use scene, a camera is started by opening a shooting application in equipment, and a preview image shot by the camera is displayed in a touch screen of the equipment so as to be viewed by a user.
It should be explained that, the subject to be photographed is a subject image that needs to be focused on in the first image to be photographed, and the subject to be photographed may include: a person image, an animal image, a still image, or the like.
For example, in one usage scenario, where a user takes a group photo in a scenic spot, then the subject of the shot may be the head portrait of the group photo. For another example, in another usage scenario, the user takes a landscape image of a building, and then the subject of the photographing may be the building.
In one case, the method of identifying a photographic subject may include: and detecting and recognizing the first image through the recognition model so as to determine the shooting subject in the first image.
The recognition model needs to be obtained by pre-training, and may be, for example, a CNN (Convolutional Neural Networks) model, a DNN (Deep Neural Networks) model, a Feature CNN model, or the like. After training, the recognition model is stored in the device and called when needed.
After the position of the subject is determined, a display frame surrounding the subject is generated, and an area corresponding to the subject in the target image sensor is set as a first sensing area. Further, in order to facilitate recognition of the first sensing region, a display frame surrounding the photographic subject may be further generated in the display screen. The display frame may be of various shapes, such as square, circular, irregular, etc.
In another case, referring to fig. 2, the method of identifying the photographic subject may include:
The first input may be various, such as a click operation, a drag operation, a slide operation, etc. by the user.
Specifically, taking the first input as an example of the pointing operation, the shooting subject in the corresponding first image is determined by the pointing operation in the display screen.
Further, in the case where the photographic subject is determined, a display frame including the photographic subject is generated, and an area corresponding to the field display frame in the target image sensor is taken as the first sensing area.
The display frame may be regular square, circular, or the like, or may be irregular.
In this way, the user can be allowed to freely select a photographing subject desired to be highlighted by determining the photographing subject through the user's input, and the user is given more creative space while helping the user easily obtain an image in which the photographing subject is highlighted.
In addition, one or more subjects may be taken; correspondingly, the number of the first display areas can be one or more.
Further, in a case where a photographic subject desired by the user is not obtained, or the user is to replace the photographic subject, or the user is to add the photographic subject, the method further includes:
and step 11, receiving a second input of the user to the displayed first image.
The second input may be various, such as a click operation, a drag operation, a slide operation, and the like of the user.
And step 12, responding to the second input, detecting and identifying the first image again to obtain an updated shooting subject and a first induction area corresponding to the shooting subject in the target image sensor.
Taking the second input as an example of the dragging operation, dragging the display frame in the image display area to an area where the shooting subject that the user needs to highlight is located, then re-identifying the image in the display frame to obtain an updated shooting subject, and taking the area surrounded by the dragged display frame as an updated first induction area.
And 103, acquiring a second image through the target image sensor under the condition that the first sensing area is in a first working mode and the second sensing area is in a second working mode.
The second sensing area is an area outside the first sensing area in the target image sensor, and the first working mode is different from the second working mode.
In this embodiment, optionally, the target image sensor is a mosaic rearrangement sensor, the first operating mode is an image reading mode, and the second operating mode is an actual size mode.
Alternatively, the mosaic rearrangement sensor may be specifically an N-in-one pixel sensor, and is not limited to the four-in-one pixel sensor shown in the drawings, and may be other sizes such as nine-in-one and sixteen-in-one, as long as it can switch between the following two operation modes. The embodiment of the present application does not specifically limit the specific size of the mosaic rearrangement sensor.
In the first working mode, a plurality of pixel points are output through the target image sensor, and then the output pixel points are rearranged through a remosaic algorithm to obtain a final second image.
In the first operation mode, also called full size mode, as shown in fig. 3, the resolution of the second image obtained by rearranging the pixel points output by the target image sensor and the surrounding associated pixel points by using a remosaic algorithm is not changed, for example, the resolution of the first image is 64M, and then the resolution of the second image is also 64M.
And in a second working mode, combining every adjacent n pixel points of the target image sensor into one pixel point, and then outputting the combined pixel points. Wherein n is an integer greater than 2.
The second operating mode, also called binning mode, as shown in fig. 4, can combine four adjacent pixels output by the sensor into 1, so as to reduce the resolution of the image, for example, the resolution of the first image is 64M, the resolution of the second image is reduced to 16M, and the brightness of each pixel is increased.
In this embodiment, the display mode of the first sensing region may be set to a full size mode, and the display mode of the second sensing region may be set to a binning mode, so that the resolution of the first display region including the shooting subject is higher than that of the second display region, thereby helping a user easily obtain an image in which the shooting subject is protruded.
Further, in addition to taking a picture to acquire an image, highlighting of the subject may be performed during video recording.
In this embodiment, acquiring the second image through the target image sensor specifically includes:
and acquiring a second image through the target image sensor in the video recording process.
After the acquiring of the second image by the target image sensor, referring to fig. 5, the method further comprises:
The tracking process may be camera movement tracking or tracking through a tracking model.
Specifically, the method comprises the following steps: and inputting the second image into the tracking model for detection to obtain a shooting subject of the second image, and further determining a first induction area corresponding to the shooting subject.
For the explanation of the first operation mode and the second operation mode, refer to the foregoing content of the embodiment, and are not described herein again.
And 503, obtaining a target video according to the second image and the third image.
That is, the finally obtained target video includes the second image and the third image. Since the second image and the third image dynamically highlight the shooting subject, the finally obtained target video can also highlight the shooting subject, so that the effect of the video is enhanced.
Through steps 501-503, the first sensing area can move along with the movement of the shooting subject by adjusting the first sensing area and the second sensing area, so that the display effect of the shot image is better.
According to the shooting method, after the first image is obtained through the camera, the shooting main body in the first image and the first induction area corresponding to the shooting main body in the target image sensor are determined, and the second image is obtained through the target image sensor under the conditions that the first induction area is in the first working mode and the second induction area is in the second working mode.
