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).

摘要： The present invention enables a circuit configuration to be simplified. An image encoding device (100) receives an input image (91) that is line-scanned in units of MBs as scan blocks, each constituted by a plurality of 4×4 blocks, while being scanned in units of 4×4 blocks as encoding blocks, each constituted by a plurality of pixels. The image encoding device (100) selects a VLC (variable length) table corresponding to a table selection index nC, which is an average value of the numbers nB and nA of nonzero coefficients as encoding values on which variable-length encoding is performed in upper-adjoining and left-adjoining 4×4 blocks of a 4×4 block as an encoding target in quantization coefficients as encoding target data based on the input image (91). At this time, in a case where the 4×4 block as an encoding target is at an upper end of an MB, the image encoding device (100) equates the number nB of nonzero coefficients of the upper-adjoining 4×4 block with the number nA of nonzero coefficients of the left-adjoining 4×4 block. The image encoding device (100) performs variable-length encoding on the number of nonzero coefficients of a 4×4 block as an encoding target in quantization coefficients using the selected VLC table.
