Patent ID: 8107749

Claim:
A color image and video encoding apparatus using inter-color-component prediction according to an encoding mode, for encoding an original image including at least two color image components, the apparatus comprising: a residue generation unit to generate a temporal residue by obtaining the difference of a current image and a prediction image obtained by estimating a motion in units of blocks between the current image and a previous image of each color image component if the encoding mode is inter mode; a residue color prediction unit to encode the temporal residue of the residue generation unit, by performing residue inter-color-component prediction considering the correlation between respective color components for removing redundant information using at least one processor; an inter compression unit to perform frequency domain transform and quantization of the result value of the residue color prediction unit using at least one processor; and an intra color prediction unit to encode the original image by performing inter-color-component prediction of the original image if the encoding mode is intra mode; an intra compression unit to perform frequency domain transform, quantization, and DC/AC coefficient prediction of the result value of the intra color prediction unit; and an entropy encoding unit to generate a bitstream by entropy encoding the result value of the inter compression unit or the intra compression unit, wherein redundant information between the color components is removed from the original image by not generating residues in the intra mode.
