An information processing apparatus is provided, which includes: a signal initialization unit that acquires an initial value of a pressure signal that is obtained after receive, by a receiving unit, of an elasticity wave from an object; an impulse response initialization unit that acquires an initial value of an impulse response of the receiving unit; and an output unit that outputs a modified pressure signal, wherein the output unit has: a signal modifying unit that modifies the pressure signal in use of the impulse response; a signal constraining unit that modifies the pressure signal based on a plurality of constraint conditions; an impulse response modifying unit that modifies the impulse response; and an impulse response constraining unit that modifies the impulse response based on constraint conditions which are time-bandwidth characteristics, and wherein the output unit generates the modified pressure signal by iteratively executing the processes. |
