Ghost Picture of a man in a window

This picture was submitted by Deanna Hooper:
Who was at her husbands cousins house for thanksgiving and right before they were to sit down for dinner - She decided to take a picture of her son and husband sitting in the sunroom. Deanna had just bought the camera and wanted to try it out there. When she downloaded the pictures onto her computer - this is what appeared. Deanna states that the tv had not been on all day and they can't explain this strange figure of the man in the window. What do you think? Is this a ghost?

Thanks Deanna for your photo submission.
