Example 1

Embodiment 1 of the present invention discloses a method for generating a picture, as shown in fig. 1, including:

step 101, obtaining the brightness value of light of the environment where the mobile terminal is located;

specifically, the step 101 of "obtaining the brightness value of the light of the environment where the mobile terminal is located" includes the following specific ways as shown in fig. 2 and fig. 3:

the method comprises the following steps of 1, acquiring an optical signal of the current environment of the mobile terminal through a light sensor;

converting the optical signal into an electrical signal;

based on processing the electrical signal, a brightness value is obtained.

Specifically, the Light Sensor is also called a brightness Sensor, and the english name is Light-Sensor, which is used for sensing the intensity of Light; the mobile terminal is generally equipped with a light sensor, and the light sensor can monitor the brightness of light at the current position of the mobile terminal. The specific processing procedure is to convert the optical signal into an electrical signal and then obtain the brightness value of the light based on the electrical signal.

Mode 2, in the mode, a camera on the mobile terminal is considered to comprise a first camera and/or a second camera; therefore, it can be considered that the brightness value is obtained by the camera, and the specific process is as follows:

Specifically, when a camera (a first camera and/or a second camera) is used for shooting, a photosensitive element inside the camera is used for photosensitive shooting areas, and further processing is embodied in the generated pre-shot images, so that the brightness value of the environment where the pre-shot images are located can be obtained through the shot images. Specifically, in order to improve the accuracy of the determination, the brightness value of each pixel in the pre-captured image generated by capturing may be counted and analyzed, so as to determine the accurate brightness value of the light of the current environment.

In order to further improve the accuracy, the method further comprises the following steps:

acquiring the geographic position and the current time of the mobile terminal;

Specifically, different geographic locations, such as the southern and northern hemispheres, and the longitude and latitude are different, the seasons are different, the time of each day is different, and the corresponding specific light is different, so that the brightness value is recorded for each time of each location, a historical brightness database is generated, such as the brightness value is still higher when the local time in summer on the northbound line of the northern hemispheres is 19, the historical brightness value is obtained based on the historical brightness database and the current geographic location (e.g., positioning by GPS) of the mobile terminal and the current time, and the measured brightness value is corrected according to the searched historical brightness value, such as when the historical brightness value is detected

Step 102, if the brightness value is smaller than a preset threshold value, acquiring a first image containing an image contour;

specifically, the brightness value is smaller than the preset threshold, which indicates that the brightness value is relatively low, for example, the mobile terminal is in a night scene, in this case, the shooting effect of the mobile terminal, for example, a mobile phone, is not good, and therefore, the first image including the image contour is obtained first.

Wherein the image contour comprises an outer edge boundary of a scene in the image and a region comprised by the outer edge boundary;

the step 102 of acquiring the first image containing the image contour includes:

controlling to start a low-light night vision device to acquire a first image;

In this embodiment, the first image is a night vision image captured by a low-light night vision device, which includes the outline and the corresponding position of the captured scene, and the outline is identified to determine the outer edge boundary of the outline, for example, a building is captured, and the outer edge line of the outline is a vertical straight line; the other scenes are respectively corresponding to the respective outlines and the outer boundary lines of the outlines, and then the image outline of each scene is determined based on the outer boundary lines.

Specifically, the "recognizing the external shape of each scene in the first image to obtain the outer edge boundary of the external shape of each scene in the first image" includes:

Specifically, the outline of the scene may be identified by a processing method of adaptive spatial filtering, and in addition, the existing other processing method may be used for processing, and specifically, only the outer edge boundary of the outline of each scene needs to be obtained by the outline identification, which is not limited to this specific method.

And wherein said controlling the low-light night vision device to acquire the first image comprises:

Specifically, in order to improve accuracy, multiple pictures can be taken at the same time through the low-light night vision device, and the multiple pictures are synthesized to generate a first image, so that more scene details can be acquired from the synthesized image, and a more accurate image profile can be acquired.

Step 103, overlapping the first image with a second image obtained by normal shooting of a camera of the mobile terminal, and determining a region to be enhanced in the second image according to the image contour; the time corresponding to the first image is the same as the time corresponding to the second image, and the image area corresponding to the first image is larger than or equal to the image area in the second image;

specifically, the second image may be a picture normally taken by a camera, and in order to further improve the definition of the image, in an embodiment, the second image obtained by the camera of the mobile terminal by normally taking the picture may be further generated by:

Therefore, the second image synthesized by a plurality of pictures shot at the same time has richer details and higher definition, is convenient for subsequent pixel enhancement processing, and reduces the subsequent processing difficulty.

Specifically, the time corresponding to the first image and the time corresponding to the second image are the same, and the specific time is the same, for example, in the order of milliseconds, that is, in the same millisecond, the time is considered to be the same, and other time, for example, microseconds, nanoseconds, and the like, may also be set according to needs.

In addition, the image area captured by the first image is greater than or equal to the image area captured by the second image, specifically, for example, the image area in the second image includes an a area, a B area; in this case, the image area in the first image needs to include at least the a area, the B area.

And the step of overlapping the first image with a second image acquired by the camera in normal shooting and determining the region to be enhanced in the second image according to the image contour comprises the following steps:

Specifically, the time information of the first image and the second image are consistent, after the alignment processing, the image areas in the first image and the second image are the same, for example, both include and only include an a area, and the image contour in the first image is, for example, a cross-shaped area located at the center of the a area; in particular, this means that the area to be reinforced in the second pattern is also the center of the a-area, in the form of a cross-shaped area.

And 104, carrying out pixel enhancement processing on the region to be enhanced to obtain a clear enhanced new picture.

After the region to be enhanced is determined, pixel enhancement processing, specifically, for example, adjustment of contrast, sharpening processing, and the like, may be performed on the enhanced region, and the specific processing manner may also be processing by using an existing pixel enhancement processing manner, so as to obtain a clear enhanced new picture.
