Abstract: A system and a method for image displaying are provided. A first electronic device activates a fill light to fill a subject. The first electronic device determines whether the illuminance of the subject is greater than a first threshold. If not, the first electronic device increases the brightness of the fill light. If yes, the first electronic device captures the subject by the image capturing circuit to obtain first color data, and transmits the first color data to a second electronic device. The second electronic device corrects the first color data and converts the corrected first color data into second color data in a color domain, and displays the subject according to the second color data.
