Abstract
A pen type input device with a camera has improved usability as a result in improved construction of the device. The pen type input device with the camera is adapted for use in detecting both of a horizontally elongated object and a vertically elongated object. On the other hand, means for pointing to the object and the process content simultaneously, and further means for detecting the fact that the user is pointing to the object in an erroneous manner and for teaching a correct manner of pointing to the object depending thereon are provided.
Claims5
A pen type input device with a camera comprising a pen, a camera mounted on said pen to pick-up an image of a penpoint, and an information processing apparatus to perform processing of an image picked up by said camera, wherein said information processing apparatus makes judgment of an orientation of an objective image picked up by said camera depending upon a position of a tip end of said pen in the image picked-up by said camera.
A pen type input device with a camera comprising a pen, a camera mounted on said pen to pick-up an image of a penpoint, and an information processing apparatus to perform processing of an image picked up by said camera, wherein said information processing apparatus extracts an object to be processed from an image picked up by said camera, determines a process to be executed on a basis of a color of the penpoint detected from the picked-up image, and performs process of said extracted object.
A pen type input device with a camera comprising a pen, a camera mounted on said pen to pick-up an image of a penpoint, and an information processing apparatus to perform processing of an image picked up by said camera, wherein said information processing apparatus detects a position of said object extracted from the image picked up by said camera and said penpoint to display an image indicating pointing of the pen on the basis of the result of detection.
A pen type input device with a camera comprising a pen, a camera mounted on said pen to pick-up an image of a penpoint, and an information processing apparatus to perform processing of an image picked up by said camera, wherein said information processing apparatus uses an image of a standard pattern as picked-up by user pointing, to extract positioning correction values to be used to correct image pick-up during use for subsequent image pickup.
