Abstract
PURPOSE:To shorten a processing time by stopping the comparison of a data length and making the difference data of a row unit into the storing data when the data length of the difference data of a character unit is longer than the data length of the difference data of the row unit. CONSTITUTION:The data length of a row unit difference buffer 4 extracted by a row unit difference extracting means and the data length of a character unit difference buffer 5 extracted by a character unit difference extracting means are compared by a comparing means every time the difference is extracted by the character unit difference extracting means. When the data length of the character unit difference buffer 5 is longer than the data length of the row unit difference buffer 4, the comparison by a comparing means is stopped and the data of the row unit difference buffer 4 are stored into a compressed file 6. When the data length of the character unit difference buffer 5 is longer than the data length of the row unit difference buffer 4, the data of the character unit difference buffer 5 are stored into the compressed file 6.
