The present invention stores relationship information on a plurality of pieces of quantized data for prediction having different MB generated code amounts on a fixed quantizer scale (QI) as prediction curves, the relationship information indicating a relationship between a plurality of quantizer scales (Q) representing a plurality of quantizer steps and MB generated code amounts. The present invention quantizes image data on a macroblock-by-macroblock basis on the single fixed quantizer scale (QI) out of the predetermined plurality of quantizer scales (Q), thereby generating temporary quantized data, and calculates the MB generated code amount of each macroblock unit of this temporary quantized data. The present invention then selects a piece of quantized data for prediction from the plurality of prediction curves based on the MB generated code amount of the temporary quantized data and the fixed quantizer scale (QI), and predicts the MB generated code amounts for situations when the image data is quantized on quantizer scales (Q) not selected by a quantization selection section, based on the selected piece of quantized data for prediction.

摘要： The present invention enables a reduction in circuit scale.In an image coding apparatus (100), as for DCT coefficients as simple coded data obtained by coding an input image (91) by simple processing, the input image (91) is coded by at least quantizing the input image (91) as an input image on the basis of selected quantization parameters (QPl) discretely selected from quantization parameters (QP) as quantization factors, thereby computing generated code sizes of the input image (91) upon coding. The image coding apparatus (100) corrects an error in the generated code sizes of the input image upon coding which occurs in accordance with the simple processing, thereby computing low-precision generated code sizes. The image coding apparatus (100) computes low-precision generated code sizes when the input image (91) is coded on the basis of quantization parameters (QP) other than the selected quantization parameters (QPl), by an interpolation process with respect to the low-precision generated code sizes when the input image (91) is coded on the basis of the selected quantization parameters (QPl).
