Portable electronic device and image data communication method thereof

An image communication method applicable to a portable electronic device, the data communication method comprising:

• enabling the portable electronic device to emulate a virtual storage device under a communication link;
• providing frame data of a corresponding frame for the portable electronic device to show and producing image data compliant with a file format according to the frame data, wherein the file format is a video file format, the image data is a video file compliant with the video file format and the video file has a cycling file structure;
• storing the image data, wherein the image data can be read through the communication link;
• and
• providing a frame data update for the portable electronic device to show and updating the image data according to the frame data update.

A portable electronic device, comprising:

• a display;
• a processing module for providing frame data of a corresponding frame for the display to show, for enabling the portable electronic device to emulate a virtual storage device under a communication link, and for producing image data compliant with a file format according to the frame data of the frame;
• and
• a memory for storing the image data, wherein the image data is readable through the communication link;
• wherein the processing module provides a frame data update for the display to show, and updates the image data according to the frame data update;
• wherein the file format is a video file format, the image data produced by the processing module is a video file compliant with the video file format, the processing module obtains a read address and calculates a next read address according to a read request under the communication link, the processing module sequentially updates the frame data for the display to show and sequentially writes the frame data update to the next read address of the image file.
