A method for video encoding mode selection and a video encoding apparatus for performing the method are provided. The method includes transforming an original image block into the frequency domain for each of two or more encoding modes, quantizing the transformed image blocks, performing distortion estimation for encoded blocks corresponding to the encode modes on the basis of quantized indices of the quantized image blocks and quantization parameters, performing rate estimation for the encoded blocks corresponding to the encode modes on the basis of quantized indices of the quantized image blocks, and performing encoding mode selection using estimated block rate values and estimated block distortion values. Hence, a method is provided that enables suitable encoding modes to be selected through efficient and effective computation of rate-distortion costs. In addition, a video encoding apparatus is provided that can execute the method. |
