PURPOSE:To always clearly print on a journal form irrespective of the brightness of a read card surface by executing the thinning processing of a dot on the basis of the arithmetic result of dot occupation ratio in the case that the image data of the read card surface is reduced by a bit conversion processing part. CONSTITUTION:This card processor is provided with an occupation ratio arithmetic part 3 to calculate the occupation ratio of the dot on the basis of the image data read by a card image reader 1, a reducing means 5 to set the degree of the reduction of the printing of the image pattern of the card surface, the bit conversion processing part 6 to reduce the read image data on the basis of the setting of the reducing means 5, and simultaneously, thin the dot of the read image data in accordance with the arithmetic result of the occupation ratio arithmetic processing part 3, and an image processing control part 9 to control these. |
