PROBLEM TO BE SOLVED: To simply create an encoding table used when reversible compression of image information is carried out. SOLUTION: Master CCD-RAW data acquired by a master photosensitive section PD1 and slave CCD-RAW data acquired by a slave photosensitive section PD2 are respectively and individually memorized in an internal memory 32. A Huffman coding-decoding section 42A of a master photosensitive section compression/expansion processing section 30A creates a master Huffman table corresponding to the master CCD-RAW data, and a Huffman coding-decoding section 42B of a master photosensitive section compression/expansion processing section 30B creates a slave Huffman table corresponding to the slave CCD-RAW data based on the master Huffman table. The master CCD-RAW data are carried out reversible compression using the master Huffman table, and the slave CCD-RAW data are carried out reversible compression using the slave Huffman table.
