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.

Provided is a method for convergent type three-dimensional (3D) multi-viewpoint image acquisition. The method for acquiring a multi-viewpoint image in an image acquisition apparatus comprises the steps of: converting the image acquisition apparatus to a multi-viewpoint image photographing mode; if converted to the multi-viewpoint image photographing mode in the converting step, providing a plurality of geometric shapes to set a position of an object to be photographed within a screen and selecting a desired shape of the geometric shapes in response to an inputted shape selection signal; if the desired geometric shape is selected in the shape providing step, adjusting a position and a size of the selected geometric shape in response to a shape adjustment signal; and photographing a whole image having the object that places within the adjusted geometric shape in the adjusting step.
