Abstract: A detection apparatus includes a sensor, a detection circuit, and a light source configured to emit light in a first color, a second color, and a third color. The detection circuit acquires a first output, a second output, and a third output that are outputs of the sensor corresponding to a period when the light in the first color is emitted, a period when the light in the second color is emitted, and a period when the light in the third color is emitted, respectively. The detection circuit adjusts at least two or more of the first, second, and third outputs based on adjustment coefficients derived so as to equalize a fourth output, a fifth output, and a sixth output. The fourth, fifth, and sixth outputs are outputs obtained when the sensor is directly irradiated with the light in the first, second, and third colors from the light source, respectively.
