ABSTRACT:
The present invention relates to an effect color extracting method of an image and an image original color recovering method which are capable of automatically extracting an effect color of an image pictured in accordance with an environment of a certain illumination and a color lens (or filter) and a feature of a camera, adjusting the extracted effect color and recovering an original image color of the image for thereby enhancing a performance of an image search. In the method for recovering an image color pictured based on a certain effect of an original color or other colors or an effect color in accordance with a feature of a camera and a surrounding environment of an object, an image color recovering method includes the steps of comparing all pixels of a frame of the image and a first critical value, obtaining an average hue value Hue_Ave with respect to the hues of the pixels each having a crominance smaller than the first critical value, computing a hue corresponding to the average hue value Hue_Ave, and determining the computed hue as an effect color, and compensating the image color affected by the effect color using the computed hue and adjusting the image color to an original color.
