Corrected entry: When Obi-Wan and Yoda are watching the video of Anakin becoming Darth Vader, and killing younglings in the Jedi temple, Obi-Wan refers to Palpatine as the Emperor - but he would not have known that Palpatine had declared himself Emperor.

Correction: In that video, Palpatine refers to the Republic as "The Empire." If it's an Empire, it has an Emperor. Obi Wan came to the logical conclusion that Palpatine had declared himself Emperor.
