Abstract:
An image recording apparatus which performs image recording by using a recording head including a plurality of nozzles discharging ink, said apparatus comprising:scanning means for scanning said recording head;driving means for driving said recording head to perform recording on a recording medium while said scanning means scans said recording head, said driving means performing the recording by discharging the ink in accordance with driving signals derived from an input image signal and corresponding to respective ones of said plurality of nozzles;correction means for correcting the image signal so as to adjust a volume of the ink to be discharged to the recording medium through a nozzle among said plurality of nozzles in said recording head in accordance with an image density represented by the input image signal, said nozzle corresponding to an edge of a region recorded by said scanning means, said correction means for making correction in accordance with not only an image signal corresponding to a nozzle corresponding to an edge of a region recorded by said scanning means, but also an image signal corresponding to neighboring nozzles near said nozzle; andmeans for generating image signals which correspond to respective ones of a plurality of inks having different concentrations belonging to the same color family based upon the image signal corrected by said correction means.
