Abstract
A colorimetric apparatus includes a detection unit configured to detect a detection target portion. The detection unit detects the detection target portion based on a change in an output value of a light reception amount at the time when a carriage straddles the detection target portion by moving in a first direction or a third direction in the detection operation. The colorimetric apparatus increases a light projection amount and executes a retry operation when the entire output value of the light reception amount of the detection unit is smaller than a first threshold in the detection operation and reduces the light projection amount and executes the retry operation when the entire output value of the light reception amount of the detection unit is larger than a second threshold in the detection operation.
