Abstract
An image recording apparatus includes plural recording heads that eject ink to record an image. Different tone characteristics of the images recorded by the recording heads are corrected by individually correcting the image signal for each head to improve the overall image quality of the image provided by the plural recording heads. Non-uniform density of the image recorded by the recording heads can also be corrected before tone correction is effected.
