摘要：An image processing apparatus for recording image data using an ink jetrecording method comprises: an ink jet nozzle to eject an ink droplet and deposit onto apaper; a controller to control the ink jet nozzle so as to enable the recording intervalwhen the ink droplet is deposited on the same position on the paper a plurality of times;a supply circuit to supply image data to the ink jet nozzle; and a distinction circuit todiscriminate whether the input image data is a half tone image or a diagram image,wherein this controller controls the recording interval in accordance with the result ofthe discrimination. With this apparatus, by superposing the recording dots on the sameposition on the paper in accordance with the binary image data, gradations and graininesscan be improved by a simple structure.
