The light intensity of the shooting interface can be obtained by a preset algorithm or by collecting light sensing data of a camera, for example, by capturing the brightness H of actual ambient light by a front camera, a rear camera or other light sensors.
The light quality of the solar light source is obtained through the following steps:
acquiring weather data corresponding to the position of the mobile terminal and the system time;
according to the weather data, acquiring the light quality of the solar light source, wherein the light quality comprises the following steps: whether there is direct light, and whether the light is hard light or soft light.
According to the position and time of the mobile terminal, the mobile terminal obtains weather data of the current shooting time of the shooting location from a background weather server, wherein the weather data comprises but is not limited to weather conditions such as rain, snow, wind frost and the like, cloud layer thickness, wind power, air pressure and the like, and light quality F (whether direct light exists, whether hard light or soft light exists or not) and expected light intensity G of the current time of the current position are obtained through the weather data.
At this time, before the step 1011, the method further includes:

Further, the step of acquiring the first angle information between the target irradiation direction and the optical axis of the camera according to the irradiation directions of the solar light source to different positions at different times in the step 1011 includes:
and determining third angle information between the solar light source and the position according to the target illumination direction, wherein the third angle information takes the horizontal ground as a reference system.
Specifically, according to the target irradiation direction, the angle between the line connecting the solar light source and the position and the horizontal ground, that is, the third angle information, can be obtained.

If the angle on the z axis is positive and is greater than a first preset angle value, the top light shooting can be determined, and if the angle on the z axis is negative and is greater than a second preset angle value, the bottom light shooting can be determined. Similarly, the corresponding illumination direction can be determined according to the relationship between the illumination angle of the sun light source on the shot human face on the x axis or the y axis and the corresponding angle threshold.
