Abstract:
1. An image processing system for encoding an image by an image encoding device and decoding the encoded image by an image decoding device, said image encoding device comprising: an encoder input unit for inputting the image to be processed; a divider for dividing a frame of the image inputted from said encoder input unit as a parent frame into a plurality of child frames; an encoder for encoding each of the child frames generated by said divider in an intra-child-frame correlation system or in an inter-child-frame correlation system; an encoder memory for storing a reference frame when the inter-child-frame correlation system is used; and an encoder output unit for outputting the image encoded by said encoder, said image decoding device comprising: a decoder input unit for inputting the encoded image; a decoder for decoding the child frames on the basis of the encoded image input from said decoder input unit in a system compatible with the system used in encoding; a decoder memory for storing the reference frame when the inter-child-frame correlation system is used; a linker for linking the child frames decoded by said decoder to generate a parent frame; a decoder output unit for outputting an image of the parent frame generated by said linker; and wherein said encoder, in a child frame encoding operation for each parent frame, is controlled to abort the encoding operation of the child frame exceeding a predetermined frame refreshing period allocated to each parent frame, and said decoder, in a child frame decoding operation for each parent frame, is controlled to abort the decoding operation of the child frame exceeding a predetermined output refreshing time allocated to each parent frame.
