PURPOSE:To enable a digital filter to be selected by a user according to an image and to enable the image to be processed stably by a method wherein a digital filter selective means and an image processing means are provided, and the image processed by the image processing means is photographically printed. CONSTITUTION:An inputted RGB signal 201 is inputted to a RGB selective circuit 204. After selecting each one color following an order of photographic printing, it is inputted to an A/D converter 205, and a digitalized image signal is once written in a line memory 206. Besides, a CPU 210 recognizes a digital filter selective switch 211, and sends a control signal to a digital processing part 207 so that any filter or a plurality of filter processings from 2071 to 2073 in the digital filter processing part 207 are executed following the digital filter selected from the outside. One line image data prepared thus are gamma converted in a photographic printing processing part 212. Thereafter, they are so converted as to conform to a driver IC of a line head 213, are sent to the line head 213, and photographic printing is performed. |
