Abstract:
An object information acquiring apparatus according to the present invention includes: an acoustic wave detecting element which detects an acoustic wave propagating from an object and which outputs an acoustic signal; a reference element which receives an input of electrical noise corresponding to electrical noise input to the acoustic wave detecting element and which outputs a reference signal; a noise reducer which reduces a component derived from the electrical noise by subtracting the reference signal from the acoustic signal; and a processor which generates image data representing characteristic information of the object using the acoustic signal in which the component derived from the electrical noise has been reduced.
