What is the definition of an idiot camera?

"Fool camera" is the common name of pocket camera. It turns out that this kind of camera is very simple to operate, and it seems that even a fool can use it to take photos with accurate exposure and clear images. In addition to simple operation, the "fool camera" has the characteristics of small size, light weight and low price, so it is also the most popular home photography tool in the world.

My understanding is that there is no need to adjust the exposure.

Do not adjust the aperture.

You can shoot it if it's on.

Now there are situational models, which models are used everywhere?
