1. Field of the Invention
The present invention relates to an image recording apparatus in which a plurality of recording heads are joined to form a composite recording head having a large recording width and an image is recorded, particularly to an image recording apparatus in which a positional shift is not caused between recorded images printed by the respective recording heads although the recording heads are not accurately positioned.
2. Description of the Related Art
In a conventional art, as described in an image correction device of Jpn. Pat. Appln. KOKAI Publication No. 2000-168109, to eliminate a positional shift caused in recording an image using a composite recording head comprising a plurality of recording heads, correction has heretofore been performed using a special image device which performs geometric correction with respect to multivalued input image data.
However, the above-described Jpn. Pat. Appln. KOKAI Publication No. 2000-168109 is not suitable for a high-speed printer, because time-consuming geometric correction needs to be performed with respect to input multivalued image data. Since a device is required for the geometric correction of the multivalued image data, there has been a disadvantage that a recording apparatus becomes expensive.
