Abstract
The nozzle error correction method is provided for adjusting information of an output image to correct an error nozzle. A position of an error nozzle firing an ink amount different from a reference value is detected from a plurality of nozzles. A determination is made from an input image as to whether a current pixel for output is an error pixel of the detected error nozzle. A channel value of the error nozzle is set to a certain value if the current pixel is the error pixel. However, if the current pixel is not the error pixel, a determination is made as to whether an error pixel exists in a certain area around the current pixel. A value of the current pixel is then adjusted based on error information. Image-processing is performed in order for the current pixel to be outputted, if the error pixel exists in the certain area. Accordingly, degradation of a print speed and a shortened life span of the head are prevented.
