These screen shots come from the Take Photo feature in Project DIVA Future Tone, which is available while you are viewing a PV. This eliminates the fake motion blur, enables the picture to be used as loading screen in the game, and (as of Update 1.05) removes the Project DIVA logo in the upper-right corner.
These songs are exclusive to Project DIVA Arcade, and were initially released from 2010 to 2012.
