Method and portable terminal for correcting gaze direction of user in image

摘要

A method and portable terminal are provided for correcting a gaze direction of a user in an image. A face of the user is detected in the image. Contour points of an eye area are detected in the detected face. The contour points of the detected eye area in the image are changed to contour points that correspond to a gaze direction toward a reference camera. The gaze direction of the user in the image is corrected by transforming the eye area according to the changed contour points.

1. A method for correcting a gaze direction of a user in an image captured by a camera, the method comprising the steps of:
detecting a face of the user in the captured image; detecting contour points of an eye area in the detected face, the eye area being defined by an eye contour connecting the contour points; changing the contour points of the detected eye area in the captured image to contour points corresponding to a gaze direction toward the camera by moving at least some of the detected contour points; and correcting the gaze direction of the user in the captured image by transforming the eye area according to a changed eye contour which connects the changed contour points, wherein detecting the contour points of the eye area in the detected face comprises setting a point having a largest change in a brightness value of a pixel in a direction of a vector passing through a contour point of a previously-set eye model, as a contour point of the eye area.
