1. An apparatus for automatically compensating for an image gradient of a mobile communication terminal display, the apparatus comprising:
- an image input unit adapted to receive a user'"'"'s image, determine the user'"'"'s line of sight, and generate user image information corresponding to the user'"'"'s line of sight;
a data process unit adapted to receive user image information from the image input unit, calculate an image gradient related to the angle between the user'"'"'s line of sight and the terminal, and generate control information corresponding to the image gradient; and
a display unit adapted to display a viewable image, the viewable image adjustable based upon the control information.

Abstract
Disclosed are an apparatus and a method for automatically compensating for an image gradient of a mobile terminal display. The apparatus and method capture a user'"'"'s image, determine the user'"'"'s line of sight, calculate an image gradient between the user'"'"'s line of sight and a reference coordinate system of the mobile terminal, and generate control information used to adjust displayed images to coordinate for the image gradient.

17. A method for automatically compensating for an image gradient of a mobile communication terminal display, the method comprising the steps of:
-
determining a user'"'"'s line of sight from a captured image and generating user image information;
calculating an image gradient between the user'"'"'s line of sight and the mobile terminal using the user image information;
generating control information corresponding to the image gradient; and
displaying a viewable image based upon the control information. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for automatically compensating for an image gradient of a mobile communication terminal display, the method comprising the steps of:
-
capturing an image of a user of the mobile communication terminal and generating user image information;
determining that the captured image contains the user'"'"'s face;
recognizing a specific portion of the user'"'"'s face in the captured image;
superimposing an arbitrary line on the specific portion of the user'"'"'s face in the user image information;
calculating an image gradient between the superimposed line and a reference line stored in the mobile terminal;
comparing the calculated image gradient to a maximum threshold value and a minimum threshold value; and
displaying a viewable image on the terminal display such that the displayed image is adjusted if the image gradient is one of greater than the maximum threshold value and less than the minimum threshold value and the displayed image is not adjusted if the image gradient is one of equal to the maximum threshold value, between the maximum threshold value and the minimum threshold value, and equal to the minimum threshold value. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
