Abstract
An image forming system executes determination processing with an intensity of an image editing process being a first intensity and a determination threshold being a first value and does not execute the determination processing with the intensity of the image editing process being the first intensity and the determination threshold being a second value. The system executes the determination processing with the intensity of the image editing process being a second intensity greater than the first intensity and the determination threshold being the first value and does not execute the determination processing with the intensity of the image editing process being the second intensity and the determination threshold being the second value.
Claims38
An image forming system comprising:
- an image former configured to form an image on a sheet;
- a reading sensor provided downstream of the image former in a conveyance direction in which the sheet is conveyed, the reading sensor being configured to read an image on the sheet conveyed from the image former;
- and
- one or more processors configured:
- to generate image data representing a result of the reading sensor reading the image on the sheet;
- to set an intensity of an image editing process applied to the image data;
- and
- to execute determination processing, on the basis of a determination threshold, to determine a degree of match between an image corresponding to reference data and an image corresponding to the image data on which the image editing process has been applied, the reference data being image data corresponding to a determination reference used in the determination processing and the determination threshold being set by the one or more processors,
- wherein the one or more processors execute the determination processing with the intensity of the image editing process being a first intensity and the determination threshold being a first value and do not execute the determination processing with the intensity of the image editing process being the first intensity and the determination threshold being a second value less than the first value, and
- wherein the one or more processors execute the determination processing with the intensity of the image editing process being a second intensity greater than the first intensity and the determination threshold being the first value and do not execute the determination processing with the intensity of the image editing process being the second intensity and the determination threshold being the second value.
