    Abstract: A color correction device for stitching a panorama and a reference image selection method using the same are disclosed. The reference image selection method for color correction during the panorama image stitching based on input images comprises the steps of: selecting an optimal reference image candidate from the input images based on a standard deviation for the overlapped areas between the images; performing the color correction for the input images based on the optical reference image candidate; and validating the optical reference image candidate based on the color corrected input images. [Reference numerals] (S200) Select an optimal reference image candidate; (S210) Perform color correction; (S220) Validate the optical reference image candidate

    Abstract: PURPOSE: An apparatus for correcting color for an image projection device and a method thereof are provided to minimize color correction procedure, by performing color correction using one sample image in a single projection or multi projection system. CONSTITUTION: A color correction device acquires a photographing image obtained by photographing a projected sample image in which an image acquisition device is projected (S100). The color correction device generates a 3D color cube by area on the basis of a color value of a block of the sample image and a color value of the photographing image, and selects a reference 3D color cube (S120,S140). The color correction device generates a look-up table for each area on the basis of the reference 3D color cube, and corrects the color of an input image by using the look-up table (S160,S180).
