[Object] To optimally adjust the specular refection component without lowered luminance[Solution] An endoscope device according to the present disclosure includes: a reflection-presence image acquisition unit that acquires a reflection-presence image containing a specular reflection component from a subject； a reflection-absence image acquisition unit that acquires a reflection-absence image not containing the specular reflection component from the subject； and a synthesis processing unit that performs synthesis of the reflection-presence image and the reflection-absence image. This configuration makes it possible to optimally adjust the specular refection component without lowered luminance, and makes it possible to optimally perform observation of the subject.
