To solve the problem that there is a case in which a generated acoustic wave is decreased owing to the attenuation of light, whereby a desired output is not obtained from an electromechanical transducer device that receives the acoustic wave.
The control apparatus for controlling an electromechanical transducer device of the present invention includes: a conversion unit that converts a current output from a first electrode of the electromechanical transducer device to a voltage; a DC voltage applying unit that applies a DC voltage to a second electrode arranged with a gap between itself and the first electrode; and a generation unit that generates a control signal which makes at least one of the DC voltage and a conversion ratio for converting the current to the voltage be changed, on the basis of information about an elapsed time from a point in time at which an inspection object was irradiated with light.
