Abstract: An image sensor controlling method is disclosed. The image sensor controlling method according to an embodiment of the present invention includes the following steps of: leading out and resetting a pixel array sequentially from the first to the n^th column of the pixel array; turning off a light source during a first time after completing the step for leading out and resetting; and leading out and resetting the pixel array sequentially from the first to the n^th column of the pixel array after the first time. The image sensor controlling method according to the embodiment of the present invention is able to increase the quality of an image because the radiation time of a light source maintains equally in every column during a photocharge storage time about each column which is included in the pixel array even the light source is turned on the off position. The present invention is also able to stop the reduction of a signal-to-noise ratio by stopping a photocharge storage with the off position of the light source.
