摘要

PROBLEM TO BE SOLVED: To convert DCF non-based JPEG data into DCF-based JPEG data and to allow this image conversion device to cooperate with other DCCF-based apparatuses.

SOLUTION: A quantization table extraction processing part 101 extracts quantization table in JPEG data and outputs the extracted quantization table to a quantization table temporary storage part 102 and a quantization table combination processing part 103. The quantization table temporary storage part 102 temporarily stores the quantization table extracted by the quantization table extraction processing part 101 and outputs the quantization table to the quantization table combination processing part 103. The quantization table combination processing part 103 combines the quantization table inputted from the quantization table temporary storage part 102 and the quantization table entered from the quantization table extraction processing part 101 to one segment, substitutes the combined segment for the quantization table in the JPEG data and outputs the substituted quantization table to a storage part such as a memory card (not shown).
