PROBLEM TO BE SOLVED: To prevent the deterioration of transmission efficiency while sufficiently expressing the content of original data.SOLUTION: A data processor 101 generates raster data with low resolution and raster data with high resolution on the basis of original data. The data processor 101 compares the raster data with low resolution with the raster data with high resolution, and determines the degree of coincidence between the raster data with low resolution and the raster data with high resolution is a predetermined threshold or more. Then, when the degree of coincidence is the threshold or more, the data processor 101 transmits the raster data with low resolution, and when the degree of coincidence is less than the threshold, the data processor 101 transmits the raster data with high resolution to an image processor 104. |
