PROBLEM TO BE SOLVED: To provide a photoacoustic imaging device capable of preventing a motion of a dynamic image displayed on a screen from being unnatural.SOLUTION: A photoacoustic imaging device 100 comprises: a light emission semiconductor element light source part 10; a detection part 20 that detects an acoustic wave AW generated from a detection object Q in an analyte P that absorbs light from the light emission semiconductor element light source part 10, and outputs a detection signal; a display part 40 that rewrites a screen 40a with a predetermined refresh rate and displays an image on the screen 40a; and a control part 30 that irradiates light by the light emission semiconductor element light source part 10 and obtains a detection signal in a sampling period SC shorter than a period RC of the refresh rate, and obtains a movement average of the detection signals detected in the sampling period SC to generate an image to be displayed on the display part 40.SELECTED DRAWING: Figure 4 |
