Step S302, acquiring the number of the filters, and dividing the panoramic picture to be processed into a plurality of sub-pictures with the same number as the filters.
Specifically, when a user selects a plurality of filters and starts filter processing, the to-be-processed panoramic picture is divided into a plurality of sub-pictures with the same number of filters, please refer to fig. 8, fig. 8 is a schematic diagram of an embodiment when the to-be-processed panoramic picture is divided into a plurality of sub-pictures with the same number of filters, as shown in fig. 8, assuming that the user selects 3 types of filters A, B, C, the mobile terminal divides the to-be-processed panoramic picture into 3 sub-pictures P1, P2, and P3, and then filter processing is performed on the sub-pictures P1, P2, and P3 with the filters A, B, C. It should be noted that, when the to-be-processed panoramic photo is divided into a plurality of sub-photos, the to-be-processed panoramic photo may be divided into average divisions or random uneven divisions, and preferably, the average division is adopted in the present embodiment, that is, the sub-photos P1, P2, and P3 all occupy one third of the size of the to-be-processed panoramic photo.

Further, based on the first embodiment described above, a second embodiment of the panoramic photograph filter processing method of the present invention is proposed. Fig. 4 is a flowchart illustrating an implementation of a panoramic photo filter processing method according to a second embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 4 may be changed and some steps may be omitted according to different requirements.

When a user selects to carry out real-time filter processing in the panoramic photo shooting process, only a plurality of filters and processing sequences selected by the user need to be utilized, and the processing area proportion corresponding to each filter does not need to be considered; when the user selects to perform subsequent filter processing on the stored panoramic picture, the multiple filters selected by the user, the processing area proportion corresponding to each filter and the processing sequence need to be utilized. Specifically, the processing area ratio is used to determine whether to divide the to-be-processed panoramic picture into 2 sub-pictures on average or according to which ratio the to-be-processed panoramic picture is divided, and if the user selects 2 filters and the processing area ratios of the filters are all 1/2, this indicates that the to-be-processed panoramic picture is divided into 2 sub-pictures on average. In addition, the processing sequence of the filters is used for indicating which sub-picture of the panoramic picture or which original picture in the shooting process of the panoramic picture is to be processed by each filter for filter processing, when the user does not set the processing sequence, the plurality of filters can be randomly distributed to the plurality of sub-pictures or the plurality of original pictures, and after the user sets the processing sequence, the plurality of sub-pictures or the plurality of original pictures arranged from left to right are processed by the filters according to the processing sequence of each filter.
