1. An information processing apparatus comprising:
a memory that stores instructions; and
a processor that executes the stored instructions to function as:
a detection unit that detects that a sheet to be fed is placed in a measurement device or a fed sheet is discharged from the measurement device;
a measurement unit that, in a case where a sheet is detected as being placed, measures a chromaticity value of a patch formed on the sheet, using the measurement device; and
a control unit that sets, to the measurement device, a first detection condition for detecting, in a first cycle, that a sheet to be fed is placed in the measurement device and a second detection condition for detecting, in a second cycle, that a fed sheet is discharged from the measurement device to mutually different detection intervals,
wherein the first cycle is longer than the second cycle, and
wherein in a case where the first condition set by the control unit is satisfied, the detection unit determines that the sheet to be fed is placed in the measurement device, and in a case where the second condition set by the control unit is satisfied, the detection unit determines that the fed sheet is discharged from the measurement device.
