Disclosed is a method for photographing a panoramic image including the steps of recognizing movement of a corresponding photographing apparatus by comparing a current real-time input image with a previous image through a motion estimation mechanism with exposure compensation, determining a time to photograph each next picture by determining whether movement in a photography direction reaches a preset threshold value, and photographing each next picture by manual or automatic operation at the determined time.

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. The background color correction step includes the sub-steps of initializing chromaticity of the white screen in advance, and correcting chromaticity using a technique of color constancy of human eyesight.

Disclosed is a method for evaluating the qualities of the user's color vision by means of the FM chromaticity test or directly measuring the defective factors of the user causing the color blindness. Thus it modifies the color composition of a video displaying apparatus according to a numerical analysis of the color and degree of color blindness specific to each dichromatic individual, so that he may perceive the same colors as the normal person. Also discloses is an apparatus for performing the method steps described herein.

A method for photographing a panoramic picture includes the steps of checking motion of a corresponding photographing apparatus compares currently input images and previous images in real time through a motion estimation technique employing exposure compensation. Respective images constituting a panoramic picture are photographed, and image photography information is checked that includes focus distance and optical magnification to calculate actual photography range distance of the images. A pre-set threshold is set in consideration of a calculated actual photography range distance of the images. The checked motion is confirmed as to whether the pre-set threshold has been reached, and photography time points of the respective images are determined. The respective images are photographed according to a manual mode or an automatic mode at the photography time point of the respective images.

A method for taking a panorama mosaic photograph includes displaying a partial image of a previously taken image as a guide image on a viewer of an image to be currently taken and taking a number of images constituting the panorama mosaic photograph according to a photography operation; projecting the taken images onto a common cylindrically curved surface; and joining the projected images into a single image.

A panoramic picture photographing method permits more accurate photographing of an image, particularly a panoramic image of a subject, without additional equipment, or separate devices and hardware. The method includes projecting an image, which is successively inputted in every predetermined unit of time, to an imaginary surface having a same focal distance in photographing each image constituting a panoramic picture to obtain a projected image; confirming movement of a corresponding photographing apparatus so that the projected image is compared with a previous image in real time by using a motion estimation technique, to which exposure correction has been applied; determining a photographing time point of each image by confirming the confirmed movement of the corresponding photographing apparatus according to a photographing direction has reached a predetermined critical value; and photographing each image at the photographing time point of each image according to a passive input or automatically.

A method for compensating an image produced by image means for implementing image information takes account of ambient illumination. Luminance of external background illumination around the image means is measured. The measured luminance of the background illumination is compared with preset tristimulus values and a reflectance factor of the image means, a comparison result is computed, and a control signal is generated to compensate luminance and chroma of an image. Luminance and chroma of the image means are compensated in response to the control signal.

Method for compensating an image

A method and an apparatus for displaying a plurality of different images in a mobile terminal in an external display device and a display unit in various modes. The mobile terminal operates according to a Different Image In and Out (DIIO) mode when the external display device is connected to the mobile terminal. When the external display device is not connected to the mobile terminal, the mobile terminal displays the plurality of different images in the display unit of the mobile terminal by operating according to a Picture-In-Picture (PIP) mode or an Overlay mode, so as to take into consideration size limitations of the display unit of the mobile terminal.
