A device and a method for removing grid noises are disclosed. The device for removing grid noises in accordance with an embodiment of the present invention calculates an average value of each line of an inputted Bayer pattern image, calculates an estimate value estimating an average of even number lines placed between the odd number lines of a Bayer pattern image and odd number lines placed between the even number lines of a Bayer pattern image, calculates a difference value between the estimate value and the average value, calculates a correction coefficient by using the difference value, and applies the correction coefficient to the Bayer pattern image and outputs a corrected Bayer pattern image.
