After determining the plurality of multimedia data, attribute information corresponding to each multimedia data may be determined by analyzing a source file of the multimedia data.
And a substep 12 of determining similar attribute information in the plurality of attribute information and using the multimedia data corresponding to the similar attribute information as a multimedia data set.
When the similarity between any two pieces of attribute information is detected, the two pieces of attribute information can be determined to be similar attribute information, and then the multimedia data containing the similar attribute information can be divided into the same multimedia data group, for example, images shot at the same time and the same place can be divided into one group.
In an embodiment of the present invention, the substep 12 may comprise the substeps of:
when the attribute information comprises time information, determining attribute information of which the time difference corresponding to the time information is within a preset time range as similar attribute information; and/or when the attribute information comprises position information, determining the attribute information of which the position difference corresponding to the position information is within a preset position range as similar attribute information; and/or when the attribute information comprises the feature information, determining that the feature information comprises the attribute information of the same local feature as similar attribute information.
In an embodiment, the attribute information may include time information, and a time difference corresponding to the time information of any two pieces of multimedia data may be calculated, and when the time difference is within a preset time range, such as 10 seconds and 1 minute, the attribute information corresponding to the two pieces of time information may be determined to be similar attribute information.

and the size of the merged packet is smaller than that of the multimedia data group corresponding to the merged packet.
After the multimedia data groups are determined, the multimedia data in each multimedia data group can be merged to obtain one or more merged packets.
In an example, the merging may include compression, such as zip compression. Of course, other manners of merging may also be adopted, for example, for multimedia data in the same multimedia data group, because of their similarities, a difference operation may be performed, that is, similar portions of multimedia data in the same multimedia data group are extracted and stored uniformly, and different portions of each multimedia data are stored separately.
In an embodiment of the present invention, before step 102, the user may preview the multimedia data set to detect whether the grouping is correct, and may enter an editing mode by long-pressing a certain multimedia data, and edit the multimedia data set in the editing mode, which may include the following steps:

Correspondingly, after the step of presenting the decomposed multimedia data group of the target merged packet, the following steps may be included:
and deleting the multimedia data group decomposed by the target merging packet.
After the display is finished, the decomposed multimedia data group can be deleted from the designated position to clear the cache and save the storage space.
