Dust particles floating near the camera lens can cause "orbs" like this. Most of the time paranormal orbs appear as singles, and the most convincing pics are the ones that show the orb moving, or an orb emerging from behind an object, which partially blocks the orb. Also, orbs in pics taken without a flash are more convincing, since it's the flash that illuminates dust or moisture to create false orbs.
Have you had any unusual activity in the room/house, that could be indicative of paranormal activity? Unusual feelings, chills, goose bumps, disorientation, sounds, smells, objects moved unexpectedly? Orbs in photos along with other evidence can help to prove or disprove if orbs in the pic are real or not.
BTW, nice TV. Do you have a full blown home theater setup?
