Abstract: Disclosed are a photoacoustic measurement apparatus capable of improving ease of observation of a photoacoustic image even if an artifact is caused by a photoacoustic wave generated in a surface portion of a subject, and a signal processing device and a signal processing method for use therein. The photoacoustic measurement apparatus includes a probe having a light emission unit and an acoustic wave detection unit provided in parallel with the light emission unit, an image generation unit which generates a photoacoustic image based on a photoacoustic wave detected by the acoustic wave detection unit, and a display processing unit which subjects the photoacoustic image to display processing for clarifying in the photoacoustic image an observation region from a position corresponding to a subject surface to an observable depth according to the interval between a reaching region on a contact plane of measurement light and the acoustic wave detection unit.
