Abstract
An apparatus, method, and medium displaying an input image according to a position of a user, extracting a position vector of the user and warping the image input to both eyes of the user according to the extracted position vector in order to provide a stereoscopic image that is not perceived as warped by the user. The apparatus for displaying an input image according to the position of a user includes a position sensing unit to sense the position of the user, a change measurement unit to measure an amount of change in position of the user, and an image correction unit to correct the input image when the amount of change meets a predetermined threshold value.
Claims20
An apparatus to display an input image according to a position of a user, the apparatus comprising:
- at least one position sensing unit to sense the position of the user;
- a change measurement unit to measure an amount of change in position of the user;
- and
- an image correction unit to correct the input image when the amount of change meets a predetermined threshold value.
A method of displaying an input image according to a position of a user, the method comprising:
- sensing the position of the user;
- measuring an amount of change in position of the user;
- and
- correcting the input image when the amount of change meets a predetermined threshold value.
An apparatus to correct an image according to a position of a user, the apparatus comprising:
- a change measurement unit to measure an amount of position change in the position of the user and a direction of the position change;
- a warping matrix generator to generate a warping matrix according to the amount and the direction of the position change of the user, the warping matrix comprising a series of vectors for shifting points on the image according to the amount and the direction of the position change of the user;
- and
- a warping performer to warp the image using the warping matrix if the amount of position change of the user meets a predetermined threshold.
