Abstract
An image forming apparatus includes circuitry and a reading device. The circuitry is configured to generate a plurality of patterns in different colors to form the plurality of patterns on a recording medium. The reading device is configured to read the plurality of patterns and a plurality of blank areas adjacent to the plurality of patterns from the recording medium. The circuitry is configured to detect a reading error of the plurality of patterns according to read values of the plurality of patterns and the plurality of blank areas and perform color calibration on a reference color by use of the read values of the plurality of patterns.
Claims9
An image forming apparatus, comprising:
- circuitry configured to generate a plurality of patterns in different colors and cause the plurality of patterns to be formed on a recording medium;
- and
- a reading device configured to read, from the recording medium, the plurality of patterns and a plurality of blank areas adjacent to the plurality of patterns to obtain read values,
- the circuitry being configured to:
- determine an error existing in the plurality of patterns, by analyzing the obtained read values of the plurality of patterns and the plurality of blank areas obtained by the reading device;
- and
- perform color calibration based on a color calibration parameter calculated by use of the read values of the plurality of patterns and the determined error.
A color calibrating method, comprising:
- generating, by circuitry, a plurality of patterns in different colors and forming the plurality of patterns on a recording medium;
- determining an error existing in the plurality of patterns by analyzing obtained read values of the plurality of patterns and a plurality of blank areas adjacent to the plurality of patterns the read values being obtained by reading, by a reading device, the plurality of patterns and the plurality of blank areas on the recording medium;
- and
- performing color calibration based on a color calibration parameter calculated by use of the read values of the plurality of patterns and the determined error.
A non-transitory, computer-readable storage medium storing computer-readable program code that causes a computer to execute a color calibrating method, the method comprising:
- generating a plurality of patterns in different colors and forming the plurality of patterns on a recording medium;
- determining an error existing in the plurality of patterns by analyzing obtained read values of the plurality of patterns and a plurality of blank areas adjacent to the plurality of patterns, the read values being obtained by reading, bye a reading device, the plurality of patterns and the plurality of blank areas on the recording medium;
- and
- performing color calibration based on a color calibration parameter calculated by use of the read values of the plurality of patterns and the determined error.
