EFFICIENT METHOD FOR ACCESSING IMAGE DATA STORED IN A CLOUD

摘要

A device transmits a request to access image data stored in a cloud and then receives an access path to the image data. If the image data are in a first data format, the device reads the image data via the access path, converts them into the second data format, and stores the converted image data in the cloud. It also modifies the access path according to a modification rule and stores the modified access path in the cloud. If the image data are in the second data format, the device either always reads the image data in the second data format via the access path or checks whether a special instruction has been defined. On the basis of the special instruction, the device either reads the image data in the second data format via the access path or remodifies the access path using the modification rule.

主权项

1. A method for accessing image data stored in a cloud, the method being carried out by a device, the method comprising:
transmitting, via the device, a request to the cloud to access the image data; receiving, at the device, an access path to the image data from the cloud; using, via the device, the access path to check whether the image data are in a first data format or in a second data format; if the image data are in the first data format, the device
reading the image data from the cloud via the access path;converting the image data inside the device into the second data format;storing the image data converted into the second data format in the cloud;modifying the access path according to a modification rule, with a result that the access path is usable to discern that the image data are stored in the cloud in the second data format; andstoring the modified access path in the cloud, if the image data are in the second data format, the device
either always reading the image data in the second data format from the cloud via the access path;or checking whether a special instruction has been predefined therefor by a user and, on the basis of the special instruction;
either reading the image data in the second data format from the cloud via the access path;or remodifying the access path using the modification rule and reading the image data in the first data format from the cloud via the remodified access path.
