IMAGE RECORDING APPARATUS

摘要

An image recording apparatus includes a first and a second recording head (11, 12) arranged adjacent to each other so that recording elements periodically arranged have a superimposed portion, image data distribution means (2) for distributing image data to these recording heads (11, 12), image data distribution region shifting means (3) for setting in a superimposed portion an image data distribution region where image data of the same pixel is distributed to the two recording heads (11, 12) by the image data distribution means (2), correction parameter storage means (5) for storing a correction parameter for correcting difference in concentration characteristic between the image data distribution region and the other region caused by a phase difference between the recording heads (11, 12), and image data correction means (4) for correcting image data of the image data distribution region according to the correction parameter.
