Summary: | A welding condition monitoring device for monitoring the welding state of a welding work portion by taking an image thereof by an image sensor having a wide dynamic range and capable of taking an image covering a very bright welding portion and relatively dark portion. The monitoring device selectively emphasizes the outputs of the image sensor for any of luminance areas of the image taken by the image sensor using a sensor output characteristic table and can provide an image clearly showing both the very bright welding portion and the dark bead portion with a sufficient contrast allowing an observer to reliably recognize the objects in the image. |
