An image scanning apparatus and method. The image scanning apparatus which scans an image of document includes a light source including at least three light emitting elements of red, green, and blue, which are sequentially lit up at intervals of a first time, a light emitting time control unit to control a light emitting time of the at least three light emitting elements such that the first time is shorter than a second time by a predetermined value, a sensor array to transform an image formed by light reflected from the document into an electric signal according to results of the control of the light emitting time and the light intensity, and an output unit to output image data corresponding to the transformed electric signal.
