## Abstract

An object information acquiring apparatus disclosed by this specification includes a detector configured to detect a photoacoustic wave generated from an object on which light is irradiated from a light source, a generator configured to generate, using the photoacoustic wave, an image indicating characteristic information in a photographing region in the object, an acquirer configured to acquire information concerning quantitativity of a measurement value of the photoacoustic wave in the photographing region, and an extractor configured to extract a region having quantitativity in the image on the basis of the information concerning quantitativity.

## Claims

### Claim 1

An object information acquiring apparatus comprising:
a detector configured to detect a photoacoustic wave generated from an object on which light is irradiated from a light source;
a generator configured to generate, using the photoacoustic wave, an image indicating characteristic information in a photographing region in the object;
an acquirer configured to acquire information concerning quantitativity of a measurement value of the photoacoustic wave in the photographing region; and
an extractor configured to extract a region having quantitativity in the image on the basis of the information concerning quantitativity.

### Claim 2 (depends on 1)

The object information acquiring apparatus according to claim 1, further comprising a display unit configured to display the image, wherein
the display unit displays an image of the region having quantitativity that has been extracted by the extractor.

### Claim 3 (depends on 1)

The object information acquiring apparatus according to claim 1, wherein
rays of light having a plurality of wavelengths are irradiated from the light source, and
the generator calculates oxygen saturation as the characteristic information by using measurement values of photoacoustic waves respectively corresponding to the rays of light having the plurality of wavelengths.

### Claim 4 (depends on 3)

The object information acquiring apparatus according to claim 3, wherein the generator calculates oxygen saturation for the region having quantitativity, on the basis of the information concerning quantitativity that has been acquired by the acquirer.

### Claim 5 (depends on 4)

The object information acquiring apparatus according to claim 4, further comprising a recording unit configured to record the information concerning quantitativity in association with the image or the oxygen saturation.

### Claim 6 (depends on 1)

The object information acquiring apparatus according to claim 1, wherein the photographing region is a region designated by a user as a region in which an image is generated on the basis of the photoacoustic wave.
