Abstract:
An ink-jet recording apparatus for recording an image by scanning a recording head having a plurality of ink discharge nozzles across a recording medium, said apparatus comprising:a reading unit for reading a recorded image recorded on the recording medium; a discriminating unit for discriminating whether or not a discharge-defective nozzle exists by detecting a differential level of density information between read density information read by said reading unit and image density information intended to be recorded; a comparing unit for comparing the differential level of density information with a predetermined density level; and a determining unit for determining, when said discriminating unit discriminates that a discharge-defective nozzle exists, a processing method to be executed, from a plurality of processing methods including a processing method of modifying a recording signal, to reduce image deterioration due to the discharge-defective nozzle based upon whether or not the differential level of density information is equal to or greater than the predetermined density level.
