Picture of North Korea's first a-bomb?

The BBC has an article up about something they noticed from a munitions conference in North Korea. The 30 minute video shows delegates walking past a serious of photographs but one stood out. It appears to show former North Korean leader Kim Jong Il with what could have been the countries first atomic bomb. 

It's not completely sure that is what is in the picture. It is fairly blurry and without much detail but it seems to show Kim Jong Il with a round object which matches designs for atomic bombs. The photo is also similar to pictures taken of Kim Jong Un with the North Korea's first hydrogen bomb.

I am kind of surprised that this is the first time this photo has shown up. The above photo with Kim Jong Un was all over the news but this one with Kim Jong Il did not. It's possible that they wanted to keep it secret but you would have thought that they would have released it for propaganda purposes. 

I have little doubt that the image is real though, even if they bomb might not be authentic. I always thought that the 2nd photo with Kim Jong Un was a mockup since I doubt he would take the risk of even being in the same room as a nuke, but that's just my thought. It's very possible that both photos are authentic.
