An image recording apparatus (2000) is disclosed, which comprises forming elements (2002) for forming an image, a memory (2006) indicating relative desirability of utilising the forming elements (2002) for forming the image, and processing means (2008) for computing image recording signals using input image signals (2012) and the stored data. The use of a particular forming element is thereby biased dependent upon the relative desirability data of other forming elements, the corresponding input signal for the particular forming element, and a term for the particular forming element.
A method of preventing image degradation due to nonejecting nozzles of a recording head is provided for an inkjet recording apparatus for recording images by ejecting ink from plural nozzles disposed in the recording head. The method according to the present invention includes the steps of measuring and recording a pattern for checking an ejection state of the head, determining a nonejecting nozzle from the pattern, obtaining density distribution for each nozzle, and determining a complementary table for every nozzle from the density distribution in the nonejecting nozzle portion for performing different-color complementing.
