Abstract

An image scanning apparatus and method are provided. The image scanning apparatus scans an image of a document and converts the scanned image into digital data, and includes light sources that emit light. The apparatus includes a light guide unit that diffuses the light emitted by the light sources and a sensor unit that senses image data from the document by recognizing light reflected from the document by being diffused by the light guide unit. The apparatus includes a control unit that controls the turning on of the light sources. The control unit alternately turns on or off the light sources such that at least one of the light sources is turned on when at least one other light source is turned off.
