OBJECT INFORMATION ACQUIRING APPARATUS AND CONTROL METHOD THEREOF, AND ACOUSTIC SIGNAL ACQUIRING APPARATUS AND CONTROL METHOD THEREOF

摘要

Provided is an object information acquiring apparatus having: a receiver in which a plurality of receiving elements to receive acoustic signals based on an acoustic wave propagated from an object is disposed on a two-dimensional surface, the plurality of receiving elements being divided into a plurality of receiving element groups including at least one receiving element respectively; a corrector that corrects signals received by the receiver; and a processor that acquires characteristic information in the object using the signals corrected by the corrector, wherein the receiver receives the acoustic signals for each of the plurality of receiving element groups with a time difference, and acquires the received signals, and the corrector corrects a time-based deviation.

1. An object information acquiring apparatus, comprising:
a receiver in which a plurality of receiving elements to receive acoustic signals based on an acoustic wave propagated from an object are disposed on a two-dimensional surface, the plurality of receiving elements being divided into a plurality of receiving element groups each including at least one receiving element respectively; a corrector configured to correct signals received by the receiver; and a processor configured to acquire characteristic information about at least a region in the object using the signals corrected by the corrector, wherein the receiver receives the acoustic signals for each of the plurality of receiving element groups with a time difference, and acquires the received signals, and the corrector corrects a time-based deviation among the received signals acquired for each receiving element group, based on the timing at which each receiving element group has received the acoustic signals.
