Abstract
To always maintain good image quality no matter whether the target bit rate for encoding is high or low. An encoderincludes: a converting sectionfor converting picture data representing a moving picture into a coefficient including a plurality of frequency components on a predetermined unit basis; a determining sectionfor determining a matrix to define a frequency bit allocation characteristic based on the resolution of the moving picture and a target bit rate for encoding that has been specified in advance; a quantization sectionfor quantizing each coefficient based on the matrix determined, thereby generating a quantized value; and an encoding sectionfor encoding the quantized value to generate encoded data of the moving picture.
