S102, determining depth information of each visual angle area according to the definition statistic value.

After the definition statistic value of each visual angle area is determined, the depth information of each visual angle area is determined according to the definition statistic value of each visual angle area. Wherein the depth information includes a depth of view level of the scene in the view area, e.g., in one embodiment, the depth of view level includes foreground and middle scenes, and background; of course, in other embodiments, the depth of field may not be limited to a limited number, and for example, multiple depths of field may be limited according to actual needs, such as the current shooting scene and/or shooting strategy. It is to be understood that the above embodiments are illustrative only and not limiting.

In one embodiment, as shown in fig. 4, step S102 includes sub-steps S1021 to S1022.

And S1021, determining the depth of field type of each visual angle area according to the definition statistic value.

Specifically, the definition statistic value of each visual angle area is analyzed, and the definition change condition of the object in each visual angle area is determined, wherein the definition change condition comprises no change in definition, monotonous rise in definition, monotonous fall in definition and a definition peak value; if the definition change condition is that the definition does not change, the depth of field type of the corresponding visual angle area is a first preset type; and if the definition change condition is that the definition is monotonically increased, the definition is monotonically decreased or has a definition peak value, the depth of field type of the corresponding visual angle area is a second preset type.

And S1022, determining depth information of each view angle area according to the depth type.

Specifically, if the depth of field type of the view angle area is a first preset type, the depth of field information of the view angle area is a null value; if the depth of field type of the visual angle area is a second preset type, determining a definition peak value or a definition change trend according to the definition statistic value; and determining the depth of field information of the visual angle area according to the definition peak value or the definition change trend. The depth information of each view angle area can be rapidly determined through the depth type.

In another embodiment, based on the sharpness variation trend, an object distance variation trend can be determined, and the depth information of the view angle area is determined according to the object distance variation trend. For example, when the zoom motor moves from infinity to the nearest end, the object distance variation tendency is monotonously decreasing in the object distance if the sharpness variation tendency is monotonously increasing in the sharpness, and the object distance variation tendency is monotonously increasing in the object distance if the sharpness variation tendency is monotonously decreasing in the sharpness. Further, if the object distance monotonically increases, the depth of field of the object can be known to be larger, and if the object distance monotonically decreases, the depth of field of the object can be known to be smaller. Of course, when the zoom motor moves from the closest end toward infinity, the object distance variation tendency is monotonously increasing for the object distance if the sharpness variation tendency is monotonously increasing for sharpness, and is monotonously decreasing for the object distance if the sharpness variation tendency is monotonously decreasing for sharpness. Further, if the object distance monotonically increases, the depth of field of the object can be known to be larger, and if the object distance monotonically decreases, the depth of field of the object can be known to be smaller.
