Abstract:
An image management method is disclosed. The method includes: receiving images; caching the received images to a memory space; determining if free memory size is less than the threshold, if yes, releasing the memory space. According to the method, mobile terminal and computer storage medium, the free memory size is determined if less than the threshold in the process of obtaining images, if yes, the memory space is released. In this way, the memory could be saved so as to provide enough space for image processing, which reduces the incidence of errors and improves the efficiency during manipulating the image.
