Employed is an information acquisition apparatus which acquires characteristic information about an object using a reception signal of acoustic waves generated by the object that is irradiated with light, the apparatus having: region acquisition unit for acquiring information indicating a plurality of regions of mutually different characteristics, in the object; sound velocity determination unit for determining sound velocity in the plurality of regions, using the information indicating the plurality of regions; and characteristic information acquisition unit for acquiring the characteristic information about the object, using the sound velocity and the reception signal.

Information acquisition apparatus and signal processing method

A dual apparatus having a first unit and a second unit of a same configuration, one being operated in an active state while the other in a standby state. Each of these first and second units comprises a first selector for setting a current unit to the active state if a predetermined fault occurs in the other unit; a second selector for sending information indicative of the setting of the current unit to the active state, if a predetermined fault occurs in the other unit and the first selector selects a first act state, to the other unit and, setting the current unit to the standby state, if the predetermined fault does not take place in the other unit and the first selector selects the active state and a state indicated by information supplied from the other unit is the active state; and a register for holding one of the active and standby states selected by the second selector.
