The present invention relates to the field of data storage, and discloses an image storage method and apparatus thereof. In the present invention, the method comprises the following steps: judging if a storage time of a current image reaches a predetermined duration; if the judgment result is yes, then determining a target region containing at least one region of interest in the current image according to the predetermined duration; generating a target region image containing the target region according to the target region, wherein the data size of the target region image is smaller than the data size of the current image; storing the target region image; deleting the current image. With the growth of storage time, redundant information in the image is gradually removed by setting different durations, so that the storage space occupied by the image can be reduced while the information of a region of interest required in various practical applications can be retained, which achieves the purpose of storing critical information in the limited storage space as long as possible. |
