For example, in fig. 3, the photo shooting lighting program 400 may be divided into a shooting module 401, a determination module 402, and a lighting module 403. The module referred to in the present invention refers to a series of instruction segments of the fetcher program that can perform specific functions, and is more suitable than the fetcher program for describing the execution process of the software in the mobile terminal 100. The detailed description of the functions of the

functional modules

401 and 403 will be described below. Wherein:

the shooting module 401 is configured to detect ambient light brightness when a shooting instruction is detected; judging whether the ambient light brightness is smaller than a preset brightness threshold value; if the judgment result is yes, the lighting function is started to increase the ambient light brightness. The invention mainly solves the problem that the picture of the existing mobile terminal is not clear under the condition of poor ambient light intensity, and the method for shooting and lighting the picture is not needed under the condition of bright ambient light, and only the existing common shooting mode (without lighting) is needed under the condition of bright ambient light. Therefore, in order to realize automatic switching between the ordinary photographing mode and the photo taking and lighting method of the present invention, the following steps may be performed when a photographing instruction is detected: (1) detecting the brightness of the environment light; (2) judging whether the ambient light brightness is smaller than a preset brightness threshold value; (3) if the judgment result is yes, the lighting function is started to increase the ambient light brightness, and if the judgment result is no, the step of taking a picture in the common picture taking mode is executed. Whether the lighting function corresponding to the photo shooting lighting method is started or not is automatically judged according to the ambient light brightness, so that manual switching of a user is avoided, and better user experience is provided for the user.

The judging module 402 is configured to detect ambient light brightness; judging whether the ambient light brightness is smaller than a preset brightness threshold value; if the judgment result is yes, the lighting function is started to increase the ambient light brightness, and if the judgment result is no, the step of taking a picture in the common picture taking mode is executed. Whether the lighting function corresponding to the photo shooting lighting method is started or not is automatically judged according to the ambient light brightness, so that manual switching of a user is avoided, and better user experience is provided for the user.

The lighting module 403 is turned on to increase the ambient light brightness, the picture of the photo shot after the ambient light brightness is enhanced is brighter and clearer, and no flash lamp is needed after the ambient light brightness is enhanced, so that the conditions of abnormal white balance, excessive exposure of the main body, dark surroundings, dazzling and influence on facial expression and the like can be avoided, and the technical problem that the shooting effect of the existing mobile terminal photo is not good under the condition of low ambient light brightness or use of the flash lamp is solved.

Through the

module

401 and 403, when the photo shooting and lighting program detects a shooting instruction, the ambient light brightness is detected, whether the ambient light brightness is smaller than a preset brightness threshold value is judged, and if the judgment result is yes, the lighting function is started to increase the ambient light brightness. The picture of the photo shot after the ambient light brightness is enhanced is brighter and clearer, a flash lamp is not needed after the ambient light brightness is enhanced, the conditions of abnormal white balance, excessive exposure of a main body, dark surrounding and dazzling which influence facial expressions and the like can be avoided, and the technical problem that the shooting effect is not good under the condition that the ambient light intensity is low or the flash lamp is used in the existing photo shooting of the mobile terminal is solved.

The dual screen of the mobile terminal includes a main screen and a sub screen 4031. The main screen and the auxiliary screen 4031 of the mobile terminal are folded, and the angle of the main screen and the auxiliary screen 4031 can be adjusted between 0-180 degrees. In this embodiment, the sub-screen 4031 displays an interface, which may be selected to be a solid color, for lighting. The shooting instruction can be executed by the front camera or the rear camera, the shooting angles of the front camera and the rear camera are different, and the user can adjust the angle of the secondary screen 4031 to be basically consistent with the shooting angle, so that the ambient light brightness of the shot picture is increased.

The tone adjusting module 4032 is configured to adjust a tone of an interface of the sub-screen 4031, so that the interface presents different tones, and further changes a tone of ambient light, and the sub-screen 4031 adjusts a tone of the ambient light while increasing ambient light brightness. In a default state, the tone of the sub screen 4031 is white. It is well known that hue is an important characteristic of color, which determines the fundamental characteristic of the nature of color. The hue is determined by which wavelength is dominant in the light reflected by the object, and different wavelengths give the impression of different colors, such as in nature, a phenomenon often seen: objects of different colors are either enclosed in a piece of golden sunlight or in a piece of light, hazy, bluish moonlight; or covered by golden yellow which is attractive in autumn; or be consolidated in the silvery-white winter world. The color is covered on the objects with different colors, so that the objects with different colors all have the same color tendency, and the color phenomenon is the color tone. If the same object is irradiated by warm color light, the object can be unified in warm color tone; if under the illumination of the cold color light, the objects are unified in the cold color tone. When the light is of a particular color, the entire object is covered in that color. Therefore, the tone of the sub-screen 4031 is adjusted by the tone adjustment module 4032, so that the photographed picture can be covered in the tone, and the user experience is improved.

The brightness adjusting module 4033 is configured to adjust the brightness of the interface of the secondary screen 4031, so as to adjust the brightness of the ambient light, and a user can adjust the brightness according to the distance between shots, so as to obtain a clear picture without overexposure.

In addition, the tone and the brightness of the sub-screen 4031 can be adjusted as required, so that the photo effect is more diversified, and the user experience is increased.

Further, a third embodiment of the photo shooting smoothing program 400 of the present invention is proposed based on the above-described second embodiment of the photo shooting smoothing program 400 of the present invention. Referring to fig. 5, fig. 5 is a functional block diagram illustrating a photo shooting and lighting procedure 400 according to a third embodiment of the present invention, wherein, compared with the second embodiment, a lighting module 403 of the photo shooting and lighting procedure 400 in this embodiment includes a flashlight 4035 and an intensity adjusting module 4036. In this embodiment, each functional module is described as follows:
