Abstract
An image file management method is applied to an image storage device. A plurality of image files is stored in the image storage device. The image file management method includes setting a first score of each image file according to a file size of each image file, setting a second score of each image file according to a storage time of each image file, and performing selective deletion of each image file according to the first score and the second score of each image file.
Claims9
An image file management method applied to an image storage device having a file management processor, a plurality of image files being stored in the image storage device, each image file having at least one GOP (Group of Pictures), the at least one GOP having an intra-frame (I-frame) and a plurality of predicted-frames (P-frames), the image file management method comprising:
- the file management processor calculating a P-frame average size of the at least one GOP of each image file stored in the image storage device;
- the file management processor calculating a ratio of an I-frame size and the P-frame average size of the at least one GOP of each image file stored in the image storage device;
- the file management processor setting a first score of each image file stored in the image storage device according to the corresponding ratio;
- the file management processor setting a second score of each image file stored in the image storage device according to a storage time of each image file stored in the image storage device;
- and
- the file management processor performing selective deletion of each image file stored in the image storage device according to the first score and the second score of each image file stored in the image storage device.
An image storage device for connecting to at least one image capturing device, the image storage device comprising:
- a non-transitory storage medium for storing a plurality of image files captured by the at least one image capturing device, each image file having at least one GOP (Group of Pictures), the at least one GOP having an intra-frame (I-frame) and a plurality of predicted-frames (P-frames);
- and
- a file management processor connected to the non-transitory storage medium for calculating a P-frame average size of the at least one GOP of each image file, calculating a ratio of an I-frame size and the P-frame average size of the at least one GOP of each image file, setting a first score of each image file according to the corresponding ratio, setting a second score of each image file according to a storage time of each image file, and performing selective deletion of each image file according to the first score and the second score of each image file.
