Method for storing multi-lens recording file and multi-lens recording apparatus

A multi-lens recording apparatus comprising:

• a plurality of lenses;
• a storage, comprising a storage space;
• a processor, coupled to the lenses and the storage and configured to:
• calculate a total recording capacity in response to one or multiple lenses among the plurality of lenses being driven to perform a loop recording, wherein each of the lenses has a lens number correspondingly, and calculating the total recording capacity comprises:
• in response to one lens among the plurality of lenses being driven to perform the loop recording, calculate a file size of a file recorded by the lens being driven based on setting data of the lens being driven and set the file size as the total recording capacity;
• and
• in response to multiple lenses among the plurality of lenses being driven to perform the loop recording, calculate file sizes of files recorded individually by the multiple lenses being driven based on respective setting data of the multiple lenses being driven and set sum of the file sizes as the total recording capacity;
• after obtaining the total recording capacity, determine whether a remaining capacity of the storage space is less than the total recording capacity;
• perform a file cleaning action on a plurality of recorded files stored in the storage space by the at least one lens in response to the remaining capacity being less than the total recording capacity, which comprises:
• deleting at least one of the recorded files stored in the storage space based on a recording time and the lens number until the remaining capacity is no less than the total recording capacity;
• and
• perform the loop recording through the at least one lens being driven and store a currently recorded file in response to the remaining capacity being no less than the total recording capacity.
