According to Samsung -- and I just confirmed it on my S22 under Camera -> Camera Setting -- it's called "Scene Optimizer"[1]:

  [ Overview of moon photography]

  Since the Galaxy S10, AI technology has been applied to the camera so that users can take the best photos regardless of time and place.

  To this end, we have developed the Scene Optimizer function, which helps AI to recognize the subject to be photographed and derive the optimal result.

  From Galaxy S21, even when you take a picture of the moon, ai recognizes the target as the moon through learned data, and multi-frame synthesis and deep learning-based ai technology when shooting. The detail improvement engine function that makes the picture clearer has been applied.

  Users who want photos as they are without AI technology can disable the optimum shooting function for each scene.
