Abstract
An image forming system includes an image forming unit, a sensor, and a controller. The controller is configured to control the sensor based on measurement modes including a first measurement mode and a second measurement mode. A sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the first measurement mode is less than a sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the second measurement mode.

An image forming system comprising:
- an image forming unit configured to form an image on a sheet;
- a conveying unit configured to convey the sheet;
- a sensor configured to move in a direction orthogonal to a conveying direction in which the conveying unit conveys the sheet, and measure the image on the sheet;
- a controller configured to control the sensor based on measurement modes, the measurement modes including:
- a first measurement mode in which a measurement result corresponding to a predetermined wavelength range is reduced from measurement results of the image;
- and
- a second measurement mode in which a measurement result corresponding to the predetermined wavelength range is not reduced from the measurement results of the image,
- wherein a sampling number of the image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the first measurement mode is less than a sampling number of the image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the second measurement mode.
