Image file processing method and device and image processing system

The embodiment of the invention discloses an image file processing method and device and an image processing system. The method comprises the following steps that a sender generates image head information data segments of an image file according to an original image file and converts each image in the image file into YUV data; the sender codes the YUN data to generate bit stream data; the sender generates compressed image data and sends the compressed image data to a receiver, wherein the compressed image data comprises the image head information data segments and the bit stream data; the receiver receives the compressed image data sent by the sender and analyzes the compressed image data to obtain the image head information data segments and the bit stream data; and the receiver generatesthe YUN data according to the bit stream data and processes the YUN data based on the image head information data segments, thereby generating the image file. Through adoption of the method, the device and the system, the fi
