    摘要: 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.

    摘要: A screen display apparatus and method of measuring an ambient brightness by adjusting color quality of an output screen in a mobile terminal according to the ambient brightness, so that the visibility of the screen can be ensured in various environments. The includes measuring an ambient brightness of the mobile terminal, and generating a visibility adjustment event when a measured ambient brightness value is equal to or greater than a preset specific external brightness value. The received RGB signal is converted into first tristimulus values, then to L, a, b color space valueslightness (L), chroma (C), and hue (H) values using a predetermined equation. The brightness of an entire region of the image is adjusted and output on the display screen of the mobile terminal, and the chroma of each pixel region is adjusted by using the L, C, and H values.
