    Abstract: PURPOSE: An adaptively selecting image encoder and a method thereof encode a current block based on encoding parameter when the spatial redundancy among the property of a reference block is higher than the temporal redundancy. CONSTITUTION: An adaptive image encoding device determines an intra prediction direction of a encoding target block (430) based on an intra prediction direction having one reference block (440) previously restored, and encodes the encoding reference block based on the determined intra prediction direction. When adaptive skip mode is used, a block existing at a relative position related to the current block is determined as the reference block. At this time, considering the correlation of the image, a decoded block most adjacent to the current block is determined as the reference block.

    Abstract: PURPOSE: An adaptable image encoding device and a method thereof are provided to perform encoding in an adaptable screen according to an encoding parameter of a peripheral block when spatial redundancy is bigger than time-based redundancy due to a local image property in the slice between screens. CONSTITUTION: A controller (310) performs the adaptable encoding based on a reference block identifier. A transmission unit transmits a bit stream including the information on the reference block identifier. An image encoding device (300) determines one reconstruction block previously reconstructed as a reference block based on the reference block identifier and determines the motion information applied to an encoding subject block based on the motion information of the reference block. The device encodes the encoding subject block based on the determined motion information. [Reference numerals] (310) Controller; (320) Storage unit; (330) Buffer

    Abstract: PURPOSE: A coding and decoding method through adaptive bit depth reduction and a device thereof are provided to increase bit depth of an input signal when the bit depth of the input signal is reduced, thereby increasing decoding efficiency. CONSTITUTION: A decoding device confirms bit depth of an input signal. When the bit depth of the input signal is reduced, a bit depth increasing unit of the decoding device increases the bit depth of the input signal(S710,S720). The decoding device restores an image by using the input signal which the bit depth is increased.
