  • Patent number: 7595906
    Abstract: Calibration associated with output density correction of a printer is effected by software calibration manipulated by the user and device calibration automatically performed by the printer, and, regarding these calibrations, high accurate calibration in which dither patterns for binarizing processing are matched to each other is effected. In a system in which either one of halftone patterns A, B, C and D as dither patterns can be used, regarding fewer number of patterns A and B, second calibration tables are created by correcting first calibration tables based on the software calibration by using correction data of engine characteristics based on the device calibration. Among the usable halftone patterns, the calibration table corresponding to the pattern A or B is selected in accordance with the set halftone pattern, and the output density correction by using the selected table.

  • Patent number: 7259892
    Abstract: A calibration for a scanner, which is used as a densitometer, is carried out always with high accuracy. More specifically, an image processing method of generating a conversion condition for a scanner which is used for reading an image and generating image data, is provided. The method including the steps of: obtaining a reading property of an object scanner based on image data obtained by that the object scanner reads a chart, and generating the conversion condition for the object scanner based on the reading property of the object scanner, a previously prepared reading property of a standard scanner and a previously prepared brightness-density conversion condition for the standard scanner.

  • Patent number: 7006246
    Abstract: An image processing method includes a step of generating a calibration condition for an image forming unit, a step of generating a calibration condition for a reading unit, and a discrimination step. The calibration condition for the image forming unit is generated by reading a first chart formed by the image forming unit with the reading unit and generating a calibration condition for the image forming unit based on the data obtained by the reading. The calibration condition for the reading unit is generated using a second chart printed in advance. In the discriminating step, the first and second charts are discriminated. The discrimination step discriminates whether a chart read in each of the step of generating the calibration condition for the image forming unit and the step of generating the calibration condition for the image reading unit is an appropriate chart.

  • Patent number: 6950197
    Abstract: A calibration process that manages calibration execution timings for a plurality of printers uniformly to keep the print characteristics of individual printers constant. More, specifically, in the printer, the calibration record information representing the time that has elapsed from the previous calibration is obtained. Based on this record information, a check is made to see whether the elapsed time has exceeded a predetermined period. When it is decided that the predetermined period of time is exceeded, a warning is displayed to urge the user to execute the calibration. With this process, the user can easily perform the calibration at predetermined intervals.
