| description | To prevent, in an image forming apparatus, the occurrence of a code reading error due to the smallness of the difference in color between a code and a background of a print to be output.SOLUTION: According to an image forming apparatus, a control unit detects a code part from image data input thereto, acquires color information on a code and color information on its background color in the code part, calculates a difference in color between the code and the background color in the code part based on the acquired color information on the code and color information on the background color, and determines whether the calculated difference in color is equal to or less than a predetermined threshold. When determining that the calculated difference in color is equal to or less than the predetermined threshold, the control unit controls such that the difference in color becomes larger than the predetermined threshold when an image is printed by an image forming unit.SELECTED DRAWING: Figure 4
【課題】画像形成装置において、出力する印刷物のコードと下地の色の差が小さいことによるコード読み取りエラーの発生を防止する。【解決手段】画像形成装置によれば、制御部は、入力された画像データからコード部を検出し、コード部におけるコードの色情報とその背景色の色情報とを取得し、取得したコードの色情報と背景色の色情報に基づいて、コード部におけるコードと背景色の色の差を算出し、算出した色の差が所定の閾値以下であるか否かを判断する。そして、算出した色の差が所定の閾値以下であると判断された場合に、画像形成部により印刷されたときの前記色の差が所定の閾値より大きくなるように制御する。【選択図】図４ |
