A method, medium and apparatus for correcting a projected image is provided. The method includes detecting a pattern image based on photographing information of consecutive image frames into which a reference pattern and an offset pattern corresponding to the reference pattern are alternately inserted and which are projected onto a projection surface accordingly, and correcting projected image frame, based on the detected pattern image.

A method and apparatus are provided for unobtrusively estimating the characteristics of a projection surface, in order to correct the distortion of images resulting from the characteristics of the projection surface in the case of a projector. The method includes projecting at least one reference pixel and at least one counterbalance pixel corresponding to the reference pixel onto consecutive image frames, and correcting an image frame to be projected using correction information determined based on photographic information of the reference pixel.

An image compensation system, method and medium that can reduce the amount of computation required for image compensation. The system may include a storage unit to store information concerning overlapping components among color light components, a separating unit to separate the color light components of an original image by removing the overlapping components from the color light components based on the stored information, prior to performing image compensation, and a projecting unit to project the separated color light components onto a screen

A system, medium, and method measuring a geometric reliability index, e.g., in image compensation, and more particularly, a system, medium, and method measuring a geometric reliability index in image compensation that can measure a geometric model of a projection surface onto which an image is projected. The system include a pattern generating unit generating first and second patterns, each having a plurality of pattern points for image compensation and the pattern points of the first pattern being different from the pattern points of the second pattern, a pattern transmitting unit transmitting the generated first and second patterns to an image projecting system, a pattern acquiring unit acquiring the first and second patterns projected onto a projection surface by the image projecting system, and a reliability index measuring unit measuring a geometric reliability index of the projection surface on the basis of a variation in position between the corresponding pattern points of the acquired first and second patterns.

An image correction apparatus, method and medium which can perform color component correction and geometric correction using the property of a projector projecting light of a plurality of color components of an input image at different times is provided. The image correction method includes sequentially projecting light of a plurality of color components of an input image onto a projection surface at different times, acquiring color components of the projected light, and correcting the input image by comparing the acquired color components with the color components of the input image.

Provided is a flat panel display (FPD), and more particularly, an FPD to display an image by controlling optical properties of a portion of the FPD. The FPD may include an image panel unit whose optical properties are locally controlled; a panel control unit to form a line field by controlling optical properties of a horizontal or vertical line region of the image panel unit; and an image input unit to project an image, which is to be output on the image panel unit, to the formed line field.

A system, method and medium tracking an action history of a user by recognizing a user's actions as predetermined indicator actions that might cause lost items, storing the user's locations whenever the indicator actions are recognized, and storing the recognized indicator actions as an action history of user to supply the user with information on the stored action history, thereby allowing the user to easily find the lost items. The system includes a location sensor to sense a location of a user, an action sensor to sense an action of the user, an action-recognition unit to recognize the sensed action as a predetermined indicator action, an action-history storage unit to store the sensed location and the recognized indicator action as the action history of the user, and an information-supply unit to supply the user with the stored action history upon request.
