    摘要: Disclosed is an apparatus and method for analyzing a histogram of an image, the apparatus comprising an image input module for buffering an input image, a block calculator for performing a blocking operation for dividing the image, which has been input to the image input module, into pixel blocks of a predetermined size, and extracting and outputting a representative pixel of each block obtained by corresponding blocking, a probability density function (PDF) operator for calculating a first histogram by using all pixels of the image, which has been input to the image input module, and calculating a second histogram by using the representative pixels input from the block calculator, and an image characteristic comparator for receiving the first and second histograms output from the PDF operator, testing if the received histograms satisfy a predetermined identity criterion by comparing characteristics of the first histogram with characteristics of the second histogram, and calculating a third histogram of the input image when it has been determined that the predetermined identity criterion is satisfied.

    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.
