    • A method and a system for simply and automatically detecting the positions of eyes, mouth, and nose in a face image with high reliability are provided. A plurality of grayscale images with gradually varying lightness are formed from a face image. Then, a process (fade-in process) is performed which detects pixel block areas that gradually appear in a face area in the grayscale images as the face area that is in a fade-out state at high lightness fades in and is brought into a fade-in state at low lightness. The detected pixel block areas include paired pixel block areas appearing as a pair. The positions of the eyes are determined based on the number of appearance of the paired pixel block areas over all the grayscale images. The positions of the mouth and nose are determined based on the positional relationship between the eyes and pixel block areas which are detected by the fade-in method and in which gradually appearing pixels no longer grow.

    • A plurality of macroblocks constituting coded data are inverse quantized using a first quantization matrix that is used when coding a picture, to obtain a plurality of sets of coefficient data. The first quantization matrix is converted to a second quantization matrix using a first conversion value and a second conversion value, where the first conversion value is for converting a low frequency coefficient corresponding to a frequency lower than a predetermined frequency among a plurality of coefficients shown by the first quantization matrix, and the second conversion value is for converting a high frequency coefficient among the plurality of coefficients and is larger than the first conversion value (Step S408). When the second quantization matrix is a matrix for increasing a coding rate of the coded data, a converted scale is calculated by multiplying a quantization scale corresponding to at least one macroblock by β1 (≧1). At least one part of the plurality of sets of coefficient data is quantized using the second quantization matrix and a calculated converted scale that corresponds to a macroblock corresponding to the at least one part of the plurality of sets of coefficient data.
