Technical Field
The invention belongs to the field of terminal camera shooting, and particularly relates to a shooting method and device, a storage medium and terminal equipment.
Background
With the development of mobile device technology, mobile devices (such as mobile phones) have become articles that users carry with them. The user uses the mobile phone to take pictures, which is a common thing, and the demand for taking pictures is increasing day by day. At present, the wide-angle lens and the telephoto lens are commonly used by mainstream mobile phone manufacturers in the market to realize optical zooming. When the camera function is turned on, the double-shot is automatically turned on. In general, a wide-angle camera is used for preview, while a telephoto camera is on standby, and a user is ready to perform a camera switching operation while zooming.
However, using this solution requires configuring the handset with a custom tele-camera, which increases the cost of the product. In addition, under normal preview, two cameras (i.e., a wide-angle camera and a telephoto camera) need to be turned on simultaneously, which results in higher power consumption.
Currently, a single camera generally adopts a digital zooming mode. Firstly, the image output by the sensor is subjected to center cutting according to the zoom factor, and then the cut part is stretched back to the size of the original output image. However, the zoom method easily causes image quality loss, and cannot meet the user's photographing requirement.
Therefore, it is desirable to provide a shooting method and device, which can improve the shooting image quality while reducing the cost and the power consumption of the mobile phone.

As shown in fig. 1, the present invention provides a shooting method suitable for an all-in-one camera, where output modes of the all-in-one camera include a first mode and a second mode.
Wherein, the all-in-one camera can include: the M unifies the camera that has N pixel, N is for being not less than 2 integer, N is the biggest pixel number that this camera image acquisition can gather.
In an embodiment of the present invention, the all-in-one camera may be a four-in-one camera. Taking a four-in-one camera as an example, the camera may include: and photosensitive elements of N pixels are subjected to light sensing, and the pixel values generated after light sensing are N. When the small-area image is captured, the luminance values of 4 adjacent pixels are weighted to improve the image quality of the small-area image (e.g., to improve the pixel luminance or sharpness), and then the weighted luminance values are regarded as the luminance value of one pixel to be output. In this way, the output image file includes only: the pixel value is N/4 pixels, and by the design, the size of the image can be reduced, meanwhile, the brightness of a single pixel in the image is improved, and the image quality is improved. The pixels included for the four-in-one camera may be, but are not limited to, 2400 ten thousand, 4800 ten thousand, 6400 ten thousand, and so on.
The photographing method includes the following steps.
Step S10, a first preview image of the first mode is acquired.
In the embodiment of the present invention, the first mode is a four-in-one mode (Binning mode), that is, after the luminance values of 4 adjacent pixels of the image are weighted, the weighted luminance values are regarded as the luminance value output of one pixel, so as to obtain the output of 1/4 size in the original size, thereby realizing displaying a larger viewing angle range under the same size, and thus improving the quality of the image.
In the embodiment of the present invention, the first mode is a default mode, that is, when the camera function is turned on, the preview photo is obtained in the first mode. In other embodiments, however, the second mode may be set to the default mode.
In step S20, it is determined whether the first preview image is zoomed.
In the embodiment of the present invention, if the first preview image is zoomed and the zoom ratio is small, the camera sensor maintains the Binning mode (first mode) output.
Step S30, when it is determined that the scaling of the first preview image is greater than a preset threshold, switch to the second mode to obtain a second preview image.
In the embodiment of the present invention, the second mode is a center region clipping mode (Crop mode), that is, the center region of the image is clipped and output, so as to obtain an output with an original size of 1/4. The Field of View (FOV) of the original frame output by the Crop mode has a 2-fold zooming effect, and this effect does not cause image quality loss.
Specifically, when the first preview image is displayed and the first preview image is zoomed (in this case, zooming operation) until the zoom ratio reaches a preset threshold, that is, the zoom ratio is greater than or equal to a preset threshold, the mode is switched to the second mode. When the output mode of the sensor in the camera is switched, the sensor needs to be rewritten in a register of the sensor, so that the second preview image needs to be opened after the first preview image is closed. The second preview image is cropped according to the zoom ratio to obtain a cropped image, and the cropped image is stretched and enlarged to obtain a second preview image.
Step S40, after the second preview image is acquired, when it is determined that the scaling of the second preview image is smaller than the preset threshold, switching to the first mode to acquire a first preview image.
In the embodiment of the present invention, when the second preview image is displayed and the first preview image is zoomed (in this case, zoom-out operation) until the zoom ratio reaches a preset threshold, that is, the zoom ratio is less than or equal to a preset threshold, the mode is switched to the first mode. When the output mode of the sensor in the camera is switched, the sensor needs to be rewritten in a register of the sensor, so that the first preview image needs to be opened after the second preview image is closed.
When high-multiple zooming operation is required, digital zooming can be performed on the basis of Crop mode output, and the effect is better than that of digital zooming performed directly under the output of a Binning mode. Because the output sizes of the two modes are the same, the first mode and the second mode are not abnormal due to dynamic switching, and the stability of the system is ensured while the picture effect is improved.
According to the embodiment of the invention, the multiple-in-one camera is adopted, the output modes of the sensors in the shooting process are dynamically switched in the previewing process, so that a user can use different output modes under the condition of different zoom levels, the effect of simulating optical zooming is achieved, and the image effect of an image is improved.
As shown in fig. 2, an embodiment of the present invention provides a shooting device, which is suitable for an all-in-one camera, where output modes of the all-in-one camera include a first mode and a second mode.

In an embodiment of the present invention, the all-in-one camera may be a four-in-one camera. Taking a four-in-one camera as an example, the camera may include: and photosensitive elements of N pixels are subjected to light sensing, and the pixel values generated after light sensing are N. When the small-area image is captured, the luminance values of 4 adjacent pixels are weighted to improve the image quality of the small-area image (e.g., to improve the pixel luminance or sharpness), and then the weighted luminance values are regarded as the luminance value of one pixel to be output. In this way, the output image file includes only: the pixel value is N/4 pixels, and by the design, the size of the image can be reduced, meanwhile, the brightness of a single pixel in the image is improved, and the image quality is improved. The pixels included for the four-in-one camera may be, but are not limited to, 2400 ten thousand, 4800 ten thousand, 6400 ten thousand, and so on.
The first mode is a four-in-one mode (Binning mode), that is, brightness values of 4 adjacent pixels of an image are weighted and then considered as a brightness value of one pixel to be output, so that 1/4-sized output of an original size is obtained, a larger viewing angle range is displayed under the same size, and the quality of the image is improved.
The second mode is a Crop mode (Crop mode) in which the central region of the image is cropped and output, and the output size of 1/4 is the original size. The Field of View (FOV) of the original frame output by the Crop mode has a 2-fold zooming effect, and this effect does not cause image quality loss.
The photographing apparatus includes: a first obtaining module 110, a second obtaining module 120, a determining module 130, and a switching module 140.
The first obtaining module 110 is configured to obtain a first preview image in the first mode.

The second obtaining module 120 is configured to obtain a second preview image in the second mode.
In the embodiment of the present invention, the second mode is a center region clipping mode (Crop mode), that is, the center region of the image is clipped and output, so as to obtain an output with an original size of 1/4. The Field of View (FOV) of the original frame output by the Crop mode has a 2-fold zooming effect, and this effect does not cause image quality loss.
The determining module 130 is connected to the first obtaining module 110 and the second obtaining module 120 respectively. The determining module 130 is configured to determine whether the first preview image is zoomed.
In the embodiment of the present invention, if the first preview image is zoomed and the zoom ratio is small, the sensor in the camera maintains the Binning mode (first mode) output.
The switching module 140 is respectively connected to the first obtaining module 110, the second obtaining module 120 and the determining module 130. The switching module 140 is configured to switch to the second mode to obtain the second preview image when it is determined that the scaling of the first preview image is greater than a preset threshold; and after the second preview image is acquired, switching to the first mode to acquire a first preview image when the scaling of the second preview image is judged to be smaller than the preset threshold.
In the embodiment of the present invention, when the first preview image is displayed and the first preview image is zoomed (in this case, zooming operation) until the zoom ratio reaches a preset threshold, that is, the zoom ratio is greater than or equal to a preset threshold, the mode is switched to the second mode. When the output mode of the sensor in the camera is switched, the sensor needs to be rewritten in a register of the sensor, so that the second preview image needs to be opened after the first preview image is closed. The second preview image is cropped according to the zoom ratio to obtain a cropped image, and the cropped image is stretched and enlarged to obtain a second preview image.

And when the second preview image is displayed and the first preview image is zoomed (zoom-out operation is performed at this time) until the zoom ratio reaches a preset threshold value, namely the zoom ratio is less than or equal to the preset threshold value, switching to the first mode. When the output mode of the camera sensor is switched, the data needs to be rewritten in a register of the sensor, so that the first preview image needs to be opened after the second preview image is closed.

When a user needs to perform high-multiple zooming, digital zooming can be performed on the basis of Crop mode output, and the effect is better than that of digital zooming performed directly under the output of a Binning mode. Because the output sizes of the two modes are the same, the first mode and the second mode are not abnormal due to dynamic switching, and the stability of the system is ensured while the picture effect is improved.
