Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In the embodiment of the present invention, the mobile terminal is provided with a first camera and a second camera. Wherein, the image collected by the first camera is mainly used for displaying for the user to preview the photo; the image collected by the second camera is mainly used for scene detection to obtain the current shooting scene. The mobile terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device) and so on.

The shooting method in the embodiment of the present invention uses the image collected by the second camera to detect the shooting scene to obtain the first scene detection result, and performs image processing on the preview image collected by the first camera according to the above first scene detection result, thereby The interference of the preview image after image processing on the shooting scene detection can be avoided, the reliability of the scene detection can be improved, and the quality of the preview image can also be improved.

Referring to Fig. 1, Fig. 1 is one of the flowcharts of the photographing method provided by the embodiment of the present invention. As shown in Fig. 1, the photographing method of this embodiment includes the following steps:

Step 101. Control the first camera to capture a preview image.

In this embodiment, after the mobile terminal detects that the camera is activated, the first camera and the second camera can be turned on at the same time to capture images respectively. Wherein, the image collected by the first camera is controlled to be displayed on the display screen of the mobile terminal for the user to preview.

Step 102, controlling the second camera to detect the shooting scene in the background, and obtain the first scene detection result.

In this step, the mobile terminal controls the second camera to collect a preview image, and in the background, that is, the control system uses the preview image collected by the second camera to detect the shooting scene, and obtain the scene type in the current environment, that is, the first scene detection result , which improves the accuracy of the scene type.

Specifically, the mobile terminal can obtain the first scene detection result of the preview image collected by the second camera through different parameters in the preview image collected by the second camera, for example, by detecting the brightness of the preview image collected by the second camera to determine Whether the first scene detection result is a night scene scene; can judge whether the first scene detection result is a backlight scene by counting and comparing the number of bright pixels and dark pixels in the preview image collected by the second camera; The pixel values of the preview images collected by the two cameras at adjacent moments are compared to determine whether the first scene detection result is a moving scene. Of course, in other embodiments, other parameters of the preview image collected by the second camera may also be used to determine whether the first scene detection result belongs to other types of scenes, which is not limited in this embodiment of the present invention. Correspondingly, in the embodiment of the present invention, the first scene detection result may be the above-mentioned night scene, backlight scene or sports scene, or other types of scene results such as indoor scene or rainy day scene.

Step 103 , based on the first scene detection result, perform image processing on the preview image captured by the first camera.

In the embodiment of the present invention, the mobile terminal may perform image processing on the preview image collected by the first camera through different image processing algorithms based on the first scene detection result. For example: for night scenes, the preview image captured by the first camera has more noise and low brightness, and a multi-frame synthesis algorithm can be implemented to improve the brightness and signal-to-noise ratio of the captured image; for backlit scenes, the preview image captured by the first camera The contrast between light and dark is strong, and the High-Dynamic Range (HDR) algorithm can be implemented to obtain high-dynamic-range images, that is, the bright parts will not be overexposed, and the details can be seen clearly in the dark; for sports scenes, the first The preview image collected by a camera is easy to blur, and an anti-shake algorithm can be implemented to reduce the blur of the captured image. Therefore, the quality of the preview image collected by the first camera can be improved.

Of course, the mobile terminal may also determine image processing parameters according to the first scene detection result, so as to use the determined image processing parameters to perform image processing on the preview image captured by the first camera, so as to improve the quality of the preview image.

It can be understood that the mobile terminal may display the preview image collected by the first camera on the display screen after performing image processing on the preview image collected by the first camera; the mobile terminal may also display the preview image collected by the first camera. , displaying a preview image, and then performing image processing on the preview image captured by the first camera based on the first scene detection result. This embodiment of the present invention does not limit it.

In addition, the mobile terminal may adjust parameters of the first camera, such as exposure time, sensitivity, aperture, etc., according to the first scene detection result. In this way, different from the preview image collected by the first camera before the parameter is adjusted, the quality of the preview image collected by the first camera after the parameter is adjusted is improved, and the quality is better. The target scene is a night scene as an example. Since the environment is dark and the light is weak at this time, the exposure time and sensitivity of the first camera can be adjusted according to the night scene to increase the brightness of the preview image and improve the quality of the preview image.

In the prior art, the image collected by the camera is used for preview and scene detection at the same time. Assuming that the night scene of the current scene is detected, if the preview image is optimized at this time to increase the brightness of the preview image, the scene detection algorithm will be based on the optimized image. The scene detected by the preview image does not conform to the night scene, the reliability of scene detection is low, and it is easy to cause frequent and continuous effect changes and flickering of the preview image. However, in the embodiment of the present invention, the mobile terminal obtains the first scene detection result through the preview image collected by the second camera, and performs image processing on the image collected by the first camera based on the first scene detection result. Therefore, different from the prior art, the present invention can avoid the interference of the target preview image on the scene detection, thereby not only improving the reliability of the scene detection, but also improving the quality of the displayed preview image.

In the embodiment of the present invention, after obtaining the first scene detection result, the mobile terminal may feed back the first scene detection result information to the first camera. Specifically, the first scene detection result information may be a representation form of the first scene detection result. In a specific embodiment, the representation form of the first scene detection result can be a numerical value, that is, different values are used to represent different first scene detection results, for example: use "1" to represent a night scene scene, "2" to represent a backlight scene, "3" represents sports scenes, etc. In this way, when the first camera reads a specific value, it can obtain the scene type corresponding to the value by looking up the mapping relationship between the preset value and the scene type, that is, the first scene detection result . Of course, in other embodiments, the first scene detection result may also be represented in other forms, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the first camera may be a main camera; the second camera may be a secondary camera, that is, an auxiliary camera.

In the shooting method of this embodiment, the first camera is controlled to collect a preview image; the second camera is controlled to detect the shooting scene in the background to obtain the first scene detection result; based on the first scene detection result, the first camera captures the Preview images for image processing. Different from the prior art, the present invention controls the second camera to detect the shooting scene in the background, obtains the result of the first scene detection, and performs image processing on the preview image collected by the first camera, so that the preview image after image processing can be avoided. The interference of shooting scene detection can improve the reliability of scene detection and improve the quality of preview image.

Referring to FIG. 2, FIG. 2 is the second flow chart of the shooting method provided by the embodiment of the present invention. The second difference between this embodiment and the above embodiment is that the second camera is controlled to detect the shooting scene in the background and obtain Before the step of the first scene detection result, the shooting method is further limited, specifically: the shooting scene detection is performed on the preview image collected by the first camera to obtain the second scene detection result; and the second scene detection is judged Whether the result is a preset scene type; if the second scene detection result is a preset scene type, then control the second camera to detect the shooting scene in the background to obtain the first scene detection result.

As shown in Figure 2, it includes the following steps:

Step 201. Control the first camera to capture a preview image.

Different from the method embodiments described above, in this embodiment, after detecting that the camera is activated, the mobile terminal first turns on the first camera, and the second camera is still turned off.

This step is the same as step 101 in the above-mentioned method embodiment. For details, reference may be made to the description in the above-mentioned embodiment. To avoid repetition, details are not repeated here.

Step 202: Perform shooting scene detection on the preview image captured by the first camera to obtain a second scene detection result.

This step is similar to step 102 in the above-mentioned method embodiment, the difference is that in this step, the preview image collected by the first camera is used to detect the shooting scene, and the second scene detection result is obtained. Therefore, for details, please refer to the above-mentioned embodiment. The description is omitted here to avoid repetition.

Step 203, judging whether the second scene detection result is a preset scene type.

In this step, the preset scene types may include, but are not limited to, night scene scenes, backlight scenes, or sports scenes. It can be understood that the preset scene types may be determined according to actual needs, which is not limited in this embodiment of the present invention. If the second scene detection result is the preset scene type, it means that the quality of the preview image captured by the second camera is poor at this time, and the preview image needs to be optimized.

In this embodiment, if the second scene detection result belongs to the preset scene type, turn on the second camera, and perform step 204; if the second scene detection result does not belong to the preset scene type, and does not receive When a photographing instruction is received, step 202 and step 203 can be repeatedly executed, and the second camera is kept turned off until the second scene detection result belongs to the preset scene type. Therefore, the power consumption of the mobile terminal can be saved.

Step 204: If the second scene detection result is a preset scene type, control the second camera to detect the shooting scene in the background to obtain the first scene detection result.

This step is the same as step 102 in the above-mentioned method embodiment. For details, reference may be made to the description in the above-mentioned embodiment. To avoid repetition, details are not repeated here.

Step 205 , based on the first scene detection result, perform image processing on the preview image captured by the first camera.

This step is the same as step 103 in the above-mentioned method embodiment. For details, reference may be made to the description in the above-mentioned embodiment. To avoid repetition, details are not repeated here.

In addition, if the obtained first scene detection result does not belong to the above-mentioned preset scene type, it means that the quality of the preview image collected by the first camera is good at this time, and there is no need to optimize its effect, so that the first camera can be turned off. Step 201 is performed again. Therefore, the power consumption of the mobile terminal can be saved.

The shooting method of this embodiment can avoid the interference of the image-processed preview image on the shooting scene detection, can improve the reliability of the scene detection, and can also improve the quality of the preview image. In addition, before turning on the first camera, the mobile terminal uses the preview image collected by the first camera to detect the scene of taking pictures, obtains the second scene detection result, and only turns on the second scene when the second detection result is determined to be a preset scene type. The camera controls the second camera to detect the shooting scene in the background, obtains the first scene detection result, and performs image processing on the preview image collected by the first camera based on the first scene detection result. Therefore, the power consumption of the mobile terminal can be saved.

Optionally, the step of controlling the second camera to perform shooting scene detection in the background to obtain the first scene detection result includes:

Control the second camera to capture preview images according to the preset preview size;

The shooting scene detection is performed on the preview image collected by the second camera to obtain a first scene detection result.

In this step, it is considered that the preview image collected by the second camera is used for shooting scene detection and not for display. Therefore, the preview size of the first camera can be adjusted to a preset preview size, the second camera is controlled to capture a preview image according to the preset preview size, and the shooting scene detection is performed on the preview image collected by the second camera to obtain the first Scene detection results. Therefore, the detection efficiency of shooting scene detection is improved, and the operation load of the mobile terminal is reduced. Wherein, the above preset preview size is smaller than the preview size of the first camera, for example, if the preview size of the first camera is 960*640 pixels, the preset preview size may be 640*480 pixels.

Optionally, the step of performing image processing on the preview image collected by the first camera based on the first scene detection result includes:

determining image processing parameters associated with the first scene detection result;

Perform image processing on the preview image captured by the first camera according to the image processing parameters.

For the convenience of understanding, the first scene detection result is a night scene scene as an example for illustration. It can be determined that the image processing parameter associated with the night scene scene is brightness, and the mobile terminal can realize the detection of the first scene by increasing the brightness of the preview image collected by the first camera. Image processing of preview images collected by a camera. The first scene detection results of other scene types may be processed in a corresponding manner, which is not limited in this embodiment of the present invention.

After the step of performing image processing on the first preview image based on the first scene detection result, further comprising:

If a photographing instruction is received, obtaining a frame of photographed image captured by the first camera;

Based on the first scene detection result, image processing is performed on the captured image to generate a photo.

It should be noted that this step is similar to step 103 in the above method embodiment, the difference is that step 103 is to perform image processing on the preview image collected by the first camera based on the first scene detection result, this step is Based on the first scene detection result, image processing is performed on the captured image captured by the first camera to generate a photo. Therefore, reference may be made to the description in step 102 for details, and details are not repeated here to avoid repetition.

Of course, in other embodiments, before the first camera captures the captured image, it can adjust the relevant parameters of the first camera according to the first scene detection result, so as to capture the number of image frames suitable for the first scene detection result, In this way, the image processing of the collected photographed images is realized. For example: for a night scene, the image captured in this scene has more noise and lower brightness, and a multi-frame synthesis algorithm can be implemented to improve the brightness and signal-to-noise ratio of the captured image. Therefore, the exposure time of the first camera needs to be adjusted , to capture multiple frames of long-exposure images; for backlit scenes, the captured images collected in this scene have a strong contrast between light and dark, and a High-Dynamic Range (HDR) algorithm can be implemented to obtain high-dynamic range images , that is, the bright places will not be overexposed, and the details can be seen clearly in the dark places. Therefore, the exposure time of the first camera can be flexibly adjusted to capture at least 3 frames of images with different exposure times; for sports scenes, in this scene The captured images are easily blurred, and an anti-shake algorithm can be implemented to reduce the blur of the captured images. Therefore, the exposure time of the first camera can be adjusted to capture multiple frames of short-exposure captured images. Thereby, the quality of the target photo can be further improved.

It should be noted that, during the process of previewing and taking pictures, the state of the second camera may remain unchanged. In addition, according to the detection result of the first scene, the means of image processing of the preview image collected by the first camera and the shot image by the mobile terminal should be as consistent as possible, so as to ensure that the preview image displayed on the display screen is basically consistent with the photo, and improve user experience.

It should be noted that this optional step is also applicable to the foregoing embodiments.
