发明名称 Method and apparatus for compressing/encoding image
摘要 According to the present invention, an image compression/encoding apparatus for determining a quantization width by which a video signal is encoded so as to encode the video signal based on the quantization width is provided. The apparatus includes control means for determining an actual bit generation number which has been consumed for encoding the video signal, determining a target bit generation number in accordance with a target bit rate, determining a bit generation error as a difference between the actual bit generation number and the target bit generation number, determining a quantization width with respect to the bit generation error, setting a characteristic in a predetermined range of the bit generation error where the quantization width varies slightly with respect to the bit generation error, and determining the quantization width with respect to the bit generation error based on the characteristic.
