1. A calibration apparatus configured to execute calibration of a display apparatus using a first measurement value, which is a measurement value of light from a screen of the display apparatus, the calibration apparatus comprising: a first acquisition unit configured to acquire a first measurement value, which is a measurement value of light from the screen of the display apparatus; a second acquisition unit configured to acquire a second measurement value, which is a measurement value of external light to the display apparatus; an allowable range determination unit configured to determine an allowable range of the first measurement value based on the second measurement value acquired by the second acquisition unit; and a measurement value determination unit configured to determine whether the first measurement value acquired by the first acquisition unit is a value within the allowable range determined by the allowable range determination unit, wherein the measurement value determination unit determines that the first measurement value is an inappropriate value in a case where the first measured value acquired by the first acquisition unit is a value outside the allowable range determined by the allowable range determination unit, and determines that the first measurement value is an appropriate value in a case where the first measurement value acquired by the first acquisition unit is a value within the allowable range determined by the allowable range determination unit.
