According to the present invention, there is provided a biochemical examination method of supplying a solution of a first biochemical material into an array of which respective second biochemical materials are held, and using a marker by a luminescent molecule to detect a luminescent intensity of the luminescent molecule for each probe array element of the array with an array type detector, so that a reaction state of the first biochemical material with the second biochemical materials is examined for each probe array element, the method comprising: irradiating a reference array by which the luminescent molecule is held with an excitation lighting to photograph a reference light image; irradiating the array for biochemical examination with the same excitation lighting to photograph a sample light image; and correcting the sample light image with the reference light image.
