Embodiment Construction
[0070] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0071] figure 1 is a functional block diagram showing the configuration of the picture encoding device according to the first embodiment of the present invention. This picture encoding device is realized based on an encoding operation of a general-purpose compression system that is Recommendation H.261 of ITU-T and MPEG-4. An uncompressed picture is input into the picture encoding device, and an encoded signal is output therefrom. As an input uncompressed picture, such a picture may use an unknown frame rate and a frame rate that changes dynamically due to frame skip operations and the like. The picture coding apparatus includes a rate control unit 100 , an image buffer 200 , an orthogonal transformation unit 300 , a quantization unit 400 , a variable length coding unit 500 , a motion prediction unit 600 , a decoding unit 700 , and an output buffer 800 .
