Abstract: An inverse conversion method for an ultra-high resolution video codec is disclosed. The inverse conversion method for an ultra-high resolution video codec according to the present invention comprises the steps of receiving a first pixel value of multiple pixel values; receiving one pixel value of the pixel values other than the first pixel value as a second pixel value; calculating a first intermediate value through a butterfly calculation by respectively applying the corresponding coefficient values to the inputted first pixel value and the second pixel value; and replacing the first pixel value with the calculated first intermediate value to re-perform the inverse conversion method.

Abstract: PURPOSE: An intra prediction apparatus of image is provided to implement an encoding/decoding of an image according to a complex algorithm while maintaining a relatively small size. CONSTITUTION: A subtractor (610) performs a subtraction calculation about first and second reference values of a prediction object pixel. A multiplier (620) performs a multiplication calculation about a parameter which is set according to an angular mode and an output value of the subtractor. A shifter (630) shifts the first reference value as N bit. An adder (640) performs an addition calculation about a value which is obtained by multiplying the first reference value by a fixed constant and an output value of the multiplier. The output value of the multiplier is a result value of an intra prediction of image according to the angular mode.
