  • Patent number: 6310988
    Abstract: A camera pen is made from a pen-like housing contains a camera and has a button for sending a signal to a computer which directs the camera to capture an image. The pen-like housing includes landing gear on one end. The landing gear has an opening which forms a flat surface that is angled such that when a user places the camera pen on a surface, the angle at which the pen rests on the surface is ergonomically comfortable for the user. Furthermore, the camera is oriented toward the opening so that when the user presses the button indicating a desire to capture an image, the camera captures the image in the opening. By combining a camera with a pen-like device, the user can comfortably capture image information from a surface.
