Claim One:
1. A photoacoustic apparatus comprising: a light source capable of individually emitting light having a first wavelength between 778 nm and 950 nm and light having a second wavelength that is different from the first wavelength; an acoustic detector that receives acoustic waves generated when the light having the first wavelength and the light having the second wavelength are respectively absorbed by an object, and converts the received acoustic waves into electric signals; an absorption coefficient distribution generator that determines absorption coefficient distributions of an object by using the electric signals; an organism characteristics distribution calculator that determines an organism characteristics distribution of the object from the absorption coefficient distributions corresponding to the light having the first wavelength and the light having the second wavelength; and a trimming unit that emphasizes the organism characteristics distribution in accordance with the absorption coefficient distribution of the object corresponding to the light having the first wavelength.
