Abstract:
Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Claim (Index 5):
A method of encoding images, the method comprising:\n generating a transformed and quantized residue signal block; and performing an adaptive scan on the transformed and quantized residue signal block based on a prediction mode, wherein the performing of the adaptive scan comprises: scanning all coefficients of a first row of the transformed and quantized residue signal block before scanning any coefficient in any other row of the transformed and quantized residue signal block in response to the prediction mode being a first mode; and scanning all coefficients of a first column of the transformed and quantized residue signal block before scanning any coefficient in any other column of the transformed and quantized residue signal block in response to the prediction mode being a second mode.
