IMAGE ENCODING DEVICE SELECTING AN ADAPTIVE ENCODING STRUCTURE AND A METHOD THEREOF CAPABLE OF IMPROVING THE CONVENIENCE AND ENCODING EFFICIENCY OF A USER BY SELECTING THE ADAPTIVE ENCODING STRUCTURE

摘要

PURPOSE: An image encoding device selecting an adaptive encoding structure and a method thereof are provided to improve a subjective picture quality by using the adaptive encoding structure when transmitting an image through various transmission lines.;CONSTITUTION: An encoding unit(110) encodes an input image block. An adaptive coding structure selector(120) compares the same image block of a current frame and a previous frame with an intra encoding mode. If intra encoding modes are same, the adaptive coding structure selector deactivates a transformation and quantization process during an encoding process of the encoding unit.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Sending end; (110) Encoder; (120) Adaptive encoding structure selector; (20) Receiving end; (200) Decoder
