Less than the duration between predeterminated frequency, the last time and the current time used more than preset duration.
In step S34, discharge the 3rd memory block, and retain the second memory block.
In this embodiment, by retaining the second memory block so that during application program scaling pictures again, as
Really the target sizes of this picture matches with the second memory block, then new without applying in virtual memory again
Memory block, thus reduce the workload of terminal, avoid virtual memory repeating apply for formed objects simultaneously
Memory block.Additionally, in the case of there is no remaining space in virtual memory, by release the 3rd memory block
Retain the second memory block so that the memory block that in virtual memory, utilization rate is relatively low can be released in time,
Thus avoid useless memory block to take the situation of virtual memory, improve the utilization rate of virtual memory.
In any of the above-described embodiment, after original image is zoomed in virtual memory, releasable non-void
Intend for decoding the first memory block of original image in internal memory, so that the first internal memory in non-virtual internal memory
Block can be cleared up in time, it is to avoid useless memory block takies the situation of non-virtual internal memory.
