An image synthesis device and a corresponding method, including first and second illumination light sources configured to illuminate an object to be detected, a light source controller configured to alternately turn on the light sources, a photographing section configured to photograph the object while the first and second illumination light sources are turned on to generate first and second images, respectively, a storage section configured to store first and second reference images generated by photographing a range of the photographing section where the illumination light sources are turned on and where the object is not present, a difference image generation section configured to generate a first difference image based on a difference between the first image and first reference image and a second difference image based on a difference between the second image and second reference image, and a synthesis section configured to synthesize the first and second difference images to generate a synthetic image. |
