Abstract
An apparatus includes an obtaining unit configured to obtain first image data obtained by reading, performed by a reading unit, a chart on which an image has not been formed by an image forming unit and second image data obtained by reading, performed by the reading unit, a chart formed by the image forming unit, and an estimation unit configured to change the second image data using the first image data and estimate a cause of an abnormality that has occurred in the image forming unit from a feature amount obtained by analyzing the changed image data.
Claims17
An apparatus comprising:
- an obtaining unit configured to obtain first image data obtained by reading, performed by a reading unit, a chart on which an image has not been formed by an image forming unit and second image data obtained by reading, performed by the reading unit, a chart formed by the image forming unit;
- and
- an estimation unit configured to change the second image data using the first image data and estimate a cause of an abnormality that has occurred in the image forming unit from a feature amount obtained by analyzing the changed second image data.
A control method of an apparatus comprising:
- obtaining first image data obtained by reading, performed by a reading unit, a chart on which an image has not been formed by an image forming unit and second image data, obtained by reading, performed by the reading unit, a chart formed by the image forming unit;
- and
- changing the second image data using the first image data and estimating a cause of an abnormality that has occurred in the image forming unit from a feature amount obtained by analyzing the changed second image data.
A computer-readable storage medium storing computer executable instructions for causing a computer to executed a control method of an apparatus, the method comprising:
- obtaining first image data obtained by reading, performed by a reading unit, a chart on which an image has not been formed by an image forming unit and second image data, obtained by reading, performed by the reading unit, a chart formed by the image forming unit;
- and
- changing the second image data using the first image data and estimating a cause of an abnormality that has occurred in the image forming unit from a feature amount obtained by analyzing the changed second image data.
