Patent ID: 8118389

Claim:
An image recording device for recording an image on a recording medium according to image data including pixel density data, comprising: a recording head that has a plurality of recording elements configured to discharge ink drops; transport means that causes the recording head and the recording medium to move relatively to each other by transporting at least one of the recording head and the recording medium; non-uniformity information acquiring means that acquires non-uniformity information of each recording element by using a test pattern; non-uniformity correction coefficient calculating means that calculates a non-uniformity correction coefficient value for each density based on the non-uniformity information of each recording element acquired by the non-uniformity information acquiring means as recording characteristics of the recording element; misfiring correction coefficient calculating means that calculates a misfiring correction coefficient value for each density in a case where a nearby recording element is misfiring based on the non-uniformity information of each recording element acquired by the non-uniformity information acquiring means as the recording characteristics of the recording element; misfiring information detecting means that detects misfiring information of the recording elements; selecting means that selects the recording characteristics calculated by the non-uniformity correction coefficient calculating means for each recording element a nearby recording element of which is not determined to he misfiring and selects the recording characteristics calculated by the misfiring correction coefficient calculating means for each recording element a nearby recording element of which is determined to be misfiring based on the pixel density data and the misfiring information detected by the misfiring information detecting means; correction processing means that corrects the pixel density data of the image data using the recording characteristics selected by the selecting means; and drive control means that drives the recording element based on the image data including the pixel density data corrected by the correction processing means.
