    Abstract: In order to obtain an inspection image without blown-out highlights generated due to specular reflection or the like or blocked-up shadows generated at a position to which light hardly reaches, an image processing device includes a plurality of light sources that irradiates an object with light and a control circuit that controls light emission of the plurality of light sources, a camera that photographs the object, and a processor that controls switching of a light emission pattern of the plurality of light sources and controls photographing execution timing of the camera, controls the plurality of light sources to emit light with a plurality of light emission patterns, performs photographing at timings during at least two or more patterns among the plurality of light emission patterns to obtain a plurality of intermediate images, and generates one final image based on the plurality of obtained intermediate images.
