<p>The shape of a cream solder is accurately detected, irrespective of a cream solder composition. An illumination setting section (95b) sets the intensity of infrared light radiated by an illuminating device (5), in accordance with the cream solder composition. An photographing device (6) irradiates a board applied with the cream solder with the infrared light having the light intensity set by the illuminating device (5). The photographing device (6) images the board irradiated with the infrared light by the illuminating device (5). As a result, an image including an image of light reflected from a surface of the board can be acquired.</p> |
