A method for designating a local representative color value and automatically determining image searching algorithm for a color based image searching system is disclosed. A method for designating a local representative color values generally includes the steps of dividing a color image area; and obtaining a color histogram for each block, obtaining a color group from hue histograms of each block, or obtaining a maximum color group value to designate the representative color value. Also, a method determining a search algorithm generally includes the steps of detecting the number of color blocks CB having color information from the blocked information of a reference image; comparing the number of the color blocks with a determined reference value and assigning different weights to at least two search algorithm according to the comparison results; and performing a comparison search of an image by the search algorithm based on the determined weight.
