Abstract: Apparatus and method for configuring a screen for a video call using a facial expression by recognizing a face from an image, calculating facial expression information for an expression of the recognized face, and determining whether there is a change in expression of the recognized face by comparing the calculated facial expression information with reference expression information preset to determine a change in expression of the face. If there is a change in expression of the recognized face, the apparatus and method selects a video image corresponding to the changed expression in the video call screen, and reconfigures the video call screen using the selected video image, making it possible for a user to conveniently select an image of the interested person without taking extensive action, and preventing a wrong image from being selected due to the unintended user facial movement.

Abstract: Disclosed is a method for correcting color in a portable image projector in consideration of an effect of a background color when the portable image projector projects images. The method corrects the effect of the background color to be projected, using color constancy technique, and thereby represents high-quality image which can be projected on a white screen. The method includes the steps of determining if a background color exists on a projection screen using a portable camera, converting the size of a mask image in order to connect a spatial position of an original image and an image photographed by a camera, correcting brightness of the mask image in order to correct non-homogeneity of the brightness of the projected image due to the distribution of different brightness values of the background color, and correcting the background color in order to correct color distortion of the image projected in different colors on the background color.
