1. An image processing device comprising:

  • a basic quantizing factor determining unit configured to determine a basic quantizing factor regarding which is predicted that the generated code quantity for each image increment when encoding an input image will approximate to the target code quantity for said each image increment;

    an encoding unit configured to encode said input image for each feedback control increment by executing quantization using a usage quantizing factor determined based on at least said basic quantizing factor; and

    a feedback control unit configured to confirm the generated code quantity of said input image encoded by said encoding unit for said each feedback control increment, and in the case of predicting that the generated code quantity for said each image increment will exceed the target code quantity for said each image increment, increase said usage quantizing factor.
