Provided are an object detection device, POS terminal device, object detection method, and program capable of carrying out appropriate processing according to whether an object is covered by a translucent container. A distance measurement unit measures the distances to each position on an opposing object. An irradiation unit irradiates light onto the object. A reflected light intensity measurement unit measures the intensities of the reflected light that has been irradiated by the irradiation unit and reflected from each position on the object. An object determination unit determines whether the object is covered by a translucent container based on the distances measured by the distance measurement unit and the reflected light intensities measured by the reflected light intensity measurement unit.
