Narrative:

I was the captain and flying pilot on takeoff roll on runway 19R. At the 80 KTS call; I checked my airspeed indicator and it was normal and indicating approximately 80 KTS. Then a few seconds later at an airspeed somewhere between 80 KTS and V1; I glanced back down at my airspeed indicator and it was showing below 80 KTS. As captain; I exercised my command decision to reject the takeoff. The rejected takeoff maneuver was completed; and we taxied clear of runway 19R. My first officer informed tower; consulted the QRH and turned on the brake fans. I made a PA announcement to the passengers and stated the reason for the rejected takeoff. I also informed them that we would be returning to the gate after our brakes had a chance to cool. We then informed operations and maintenance and returned to the gate. After consulting with maintenance; we deplaned the passengers without incidence. I then called dispatch and informed the dispatcher of the event. Systems scheduling then decided to cancel the flight. The event occurred due to a faulty and inaccurate airspeed indication.
