Image processing method and apparatus thereof

An image processing apparatus having a reader which reads an original image, an image processor which is capable of executing plural kinds of image processing, a corrector which corrects image data output from the image processor, and a forming section which forms an image on a recording medium based on image data output from the corrector, said apparatus further comprising:

• a generator, arranged to generate sample data to which the image processing is applied by the image processor, and to control the forming section to form a sample chart based on the sample data, wherein said generator adds information to the sample data to append identification information, which indicates the kind of image processing used in the generation of the sample data, to the sample chart;
• an updater, arranged to update tone correction characteristics of the corrector corresponding to the image processing based on image data of the sample chart acquired by the reader, wherein the sample chart is conveyed using a feeder of the reader, and said updater identifies the kind of image processing corresponding to the tone correction characteristics to be corrected from the identification information appended to the sample chart;
• and
• a controller, arranged to control said generator and said updater in accordance with an input user instruction indicating image processing used to update the tone correction characteristics of the plural kinds of image processing.

A method of controlling an image processing apparatus having a reader which reads an original image, an image processor which is capable of executing plural kinds of image processing, a corrector which corrects image data output from the image processor, and a forming section which forms an image on a recording medium based on image data output from the corrector, said method comprising the steps of:

• generating sample data to which the image processing is applied by the image processor, and controlling the forming section to form a sample chart based on the sample data;
• updating tone correction characteristics of the corrector corresponding to the image processing based on image data of the sample chart acquired by the reader, wherein the sample chart is conveyed using a feeder of the reader;
• and
• controlling the generating step and the updating step in accordance with an input user instruction indicating whether or not to execute batch update processing of the tone correction characteristics of the corrector corresponding to the plural kinds of image processing,
• wherein, when the batch update processing is instructed, information is added to the sample data to appends identification information, which indicates the kind of image processing used in the generation of the sample data, to the sample chart in the generating step, and the kind of image processing corresponding to the tone correction characteristics to be corrected is identified from the identification information appended to the sample chart in the updating step.
