Please refer to Fig. 1, the photograph processing method in the embodiment of the present invention comprises:

Step 101, receiving a camera instruction;

In the embodiment of the present invention, the photographing instruction is used to trigger the camera of the electronic terminal to perform the photographing action. Specifically, when the camera of the electronic terminal is started (started in the foreground or started in the background), the user can input the camera instruction by triggering the preset camera button (the camera button can be a virtual button or a physical button), or by inputting The camera instruction is input in a preset voice mode, and the embodiment of the present invention does not limit the specific input method of the camera instruction.

Optionally, step 101 is specifically receiving a photographing instruction in a screen-off photographing mode. Wherein, the above-mentioned off-screen photographing mode refers to a photographing mode in which the camera of the electronic terminal operates in the background when the electronic terminal is in a screen-off state. In the embodiment of the present invention, the above-mentioned electronic terminal is equipped with an interface for starting the photo mode with the screen off, so that the user can trigger the startup and operation of the photo mode with the screen off through the interface for starting the photo mode with the screen off when the electronic terminal is in the state of the screen off. Specifically, the startup interface of the screen-off camera mode can be represented as a physical button (for the convenience of description, the physical button is described as an A key), and when the above-mentioned electronics is in the screen-off state, the user triggers the A button (for example, clicks , double-click or long-press the A key) to trigger the startup and operation of the above-mentioned off-screen photo mode. Alternatively, the interface for starting the screen-off camera mode can also be in other forms. For example, the interface for starting the screen-off camera mode can also be represented as a touch input interface. Input a preset gesture to trigger the startup and operation of the above-mentioned screen-off camera mode. In the embodiment of the present invention, no specific limitation is imposed on the starting manner of the above-mentioned off-screen photographing mode. The start-up and operation of the above-mentioned off-screen photographing mode is specifically shown as: starting the camera of the above-mentioned electronic terminal in the background (the camera can be a built-in camera of the above-mentioned electronic terminal, or can also be an external camera for the above-mentioned electronic terminal). Wherein, the above-mentioned starting the camera of the above-mentioned electronic terminal in the background refers to starting the camera to enter shooting preparation but not displaying the preview window of the camera.

In an application scenario, it may be detected whether there is an unfocused image in the N images, and if there is an unfocused image, the unfocused image is determined as a blurred image. Wherein, the above-mentioned unfocused image refers to an image obtained by taking pictures of the above-mentioned camera when it is not in focus (for example, in the case of focus failure or future focus).

Since the adjacent pixels in the blurred image are usually relatively smooth, in another application scenario, the following processing can also be performed on each of the above N images one by one: calculate the adjacent pixels in each image The difference between pixels; if the proportion of the difference less than the preset threshold to all the differences in the same image is greater than the preset ratio, it is determined that the corresponding image is a blurred image; if the difference less than the above preset threshold accounts for the same image If the ratio of all the difference values in is not greater than the preset ratio, it is determined that the corresponding image is a non-blurred image. For example, for a 100*100 image, by calculating the difference between adjacent pixels in the image, 99*99 differences will be obtained. If the preset ratio is 10%, then if the 99* Among the 99 difference values, if the number of difference values smaller than the above-mentioned preset threshold is greater than 99*99*10%, it is determined that the image is a blurred image; if among the 99*99 difference values, the number of difference values smaller than the above-mentioned preset threshold If the number of difference values is not more than 99*99*10%, it is determined that the image is a non-blurred image.

The embodiment of the present invention does not limit the specific implementation manner of determining the blurred image in the above N images.

Step 104, selecting an image from the images other than the blurred image among the above N images;

In the embodiment of the present invention, an image may be randomly selected from the images other than the blurred image among the N images. Of course, if there is only one image other than the blurred image among the N images , select the image directly.

For example, if the above-mentioned N is 10, step 103 determines that there are 6 blurred images in the above-mentioned N images, then in step 104, from the remaining 4 images (that is, except the above-mentioned 6 blurred images in the above-mentioned 10 images) Select an image from the image in .

Step 105, output the selected image;

In the embodiment of the present invention, the image selected in step 104 is output as the photo obtained by taking this time.

Specifically, step 105 may be expressed as storing the image selected in step 104, for example, storing the image selected in step 104 in the above-mentioned electronic terminal.

Further, if the embodiment of the present invention is to perform the photographing process in the screen-off photographing mode, only the image selected in step 104 may be stored at this time and the image will not be displayed. Therefore, while or after outputting the image, you can also A reminder signal is output, so that the user is reminded that the image has been output through the reminder signal. Specifically, the type of the reminder signal may be one or a combination of two or more of the following: sound, vibration and indicator light.
