ABSTRACT:
An image processing apparatus for recording image data using an ink jet recording method comprises: an ink jet nozzle to eject an ink droplet and deposit onto a paper; a controller to control the ink jet nozzle so as to enable the recording interval when 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 to discriminate 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 of the discrimination. With this apparatus, by superposing the recording dots on the same position on the paper in accordance with the binary image data, gradations and graininess can be improved by a simple structure.
