detailed description

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.

As shown in FIG. 1, an embodiment of the present invention provides a shooting method, which is applied to a mobile terminal, and the shooting method includes:

Step 101, monitor the shooting object in the shooting preview interface.

In this step, the mobile terminal has at least one camera, at least one camera is activated through the application program, and the object to be photographed in the shooting preview interface of the camera is monitored through the activated camera.

Step 102: If it is detected that there are both moving objects and stationary objects in the shooting preview interface, and a shooting instruction is received, exposure is performed using the first exposure time and the second exposure time respectively to generate a first image and a second image.

In this step, the monitoring of the moving object and the stationary object can be determined by comparing consecutive multiple frames of preview images, which is not specifically limited here.

Specifically, the first exposure time is shorter than the second exposure time, that is, the first exposure time is a short exposure time, and the second exposure time is a long exposure time. Generally speaking, since the first image is an image obtained by exposing with the first exposure time (ie, short exposure time), the noise of the stationary object on the first image is generally larger, while the noise of the moving object on the first image is relatively large. Clear; at the same time, since the second image is an image obtained by exposing with the second exposure time (ie, long exposure time), the moving objects on the second image are blurred, while the noise of the stationary objects on the second image is relatively small.

Step 103, performing image synthesis on the first image and the second image to generate a target image including the moving object and the stationary object; wherein, the first exposure time is used for the image area where the moving object is located Exposure is performed, and the image area where the stationary object is located is exposed using the second exposure time.

In order to make the moving object in the image captured by the mobile terminal clearer and the noise of the stationary object smaller, this step uses a preset algorithm to perform image synthesis on the first image and the second image, so that the image area where the moving object in the target image is located uses the Expose at the first exposure time, and the first exposure time is a short exposure time, thereby avoiding the blurring of the moving object, making the moving object in the target image clear, and improving the image quality; at the same time, the image area where the static object in the target image is located adopts the described method. Exposure is performed at a second exposure time, and the second exposure time is a long exposure time, thereby reducing noise of a still object and improving image quality; thus improving user visual experience.

It should be noted that the above-mentioned steps 102 and 103 are both processes performed by the background of the mobile terminal (such as an image processor ISP). The exposure process and synthesis process of the target image do not need to be displayed to the end user, further improving the user's visual experience.

Further, before step 102 in the above-mentioned embodiments of the present invention, the method further includes:

Determine the first exposure time of the moving object; that is, the first exposure time is a short exposure time corresponding to the moving object.

A preset second exposure time of the stationary object is acquired; that is, the second exposure time is a long exposure time corresponding to the stationary object.

It should be noted that the second exposure time of the stationary object is preset by the mobile terminal, which may be set when the mobile terminal leaves the factory, manually set by the user, or the exposure time last used by the terminal, etc., here Not specifically limited.

Further, in the above embodiments of the present invention, the step of determining the first exposure time of the moving object includes:

Acquiring the current speed of the moving object;

determining a target speed interval corresponding to the current movement speed;

According to the preset corresponding relationship between the speed range and the exposure time, the exposure time corresponding to the target speed range is determined as the first exposure time of the moving object.

In the above-mentioned embodiments of the present invention, the current moving speed of the moving object is detected by the mobile terminal, for example, detecting the displacement of the moving object within a preset time period, thereby calculating the moving speed; Estimating the current moving speed of the moving object, which is not specifically limited here.

Preferably, in order to avoid the increase of terminal power consumption caused by the constant change of the first exposure time, the embodiment of the present invention presets the corresponding relationship between the speed range and the exposure time, for example, the exposure time corresponding to the speed range [V1, V2] is t1; The exposure time corresponding to the speed interval (V2, V3] is t2; the exposure time corresponding to the speed interval (V3, V4] is t3, etc., which are not listed here.

After determining the current moving speed of the moving object, the terminal determines which speed interval it is in, and determines the exposure time corresponding to the speed interval as the first exposure time of the moving object. For example, the current moving speed of the moving object is 5 km/h, if 5 km/h falls within the speed interval [V1, V2], then the first exposure time of the moving object is t1.

It should be noted that the setting of the corresponding relationship between the speed interval and the exposure time needs to meet the requirement that using the exposure time to expose the moving object in the speed interval can reduce the blur of the moving object, that is, using the exposure time to the movement in the speed interval The clarity of the moving object obtained by exposing the object; the setting of its specific value can be obtained through multiple test data, and will not be described in detail here.

Further, step 103 in the above-mentioned embodiment of the present invention includes:

extracting a moving object image area from the first image;

extracting a still subject image region from said second image;

Image synthesis is performed on the moving object image area and the still object image area to generate a target image including the moving object and the still object.

In order to make the moving object in the image captured by the mobile terminal clearer and the static object less noisy, this step uses a preset algorithm to perform image synthesis on the first image and the second image, specifically, extract the moving object image from the first image area, the moving object image area is obtained by using the first exposure time for exposure processing, so that the blurring of the moving object can be avoided, the moving object in the target image is clear, and the image quality is improved; and the still object image is extracted from the second image area, the image area of the still object is obtained by using the second exposure time for exposure processing, thereby reducing the noise of the still object and improving the image quality; preferably, the image area where the moving object in the target image is located uses the first exposure time Perform exposure, the first exposure time is a short exposure time, so that the blurring of the moving object can be avoided, the moving object in the target image is clear, and the image quality is improved; at the same time, the image area where the static object in the target image is located adopts the second exposure time Exposure is performed, and the second exposure time is a long exposure time, so that the noise of the stationary object can be reduced, and the image quality can be improved; thus, the user's visual experience can be improved.

It should be noted that the photographing method provided by the above embodiments of the present invention may not only be applicable to photographing applications, but also applicable to video recording applications. Specifically, if the photographing instruction is a photographing instruction, the target image is an image captured in response to the photographing instruction; the photographing application can save the target image (it can be saved to the gallery by default, or it can be saved in response to user operations Save to the location that the user wants to store), and edit the target image, etc., which are not specifically limited here.

If the shooting instruction is a video recording instruction, the target image is a frame image in the video shot in response to the video recording instruction; if there are also moving objects and stationary objects in the next frame preview interface, then according to this The above-mentioned method of the embodiment of the invention generates the next frame of image; if there are only moving objects or only static objects in the preview interface of the next frame, then the next frame of image is generated according to the existing flow (for example, using an exposure time to perform exposure processing to generate the next frame of image). a frame of image), and will not be described in detail here.
