Abstract: A fixed pattern noise removal method for an image sensor includes steps of calculating each compensation value corresponding to each pixel column according to a plurality of compensation pixel values of the each pixel column; and sampling a plurality of active pixel values in an active pixel area and compensating the plurality of active pixel values according to the each compensation value of the each pixel column, to generate a plurality of compensated active pixel values. A plurality of active pixels sense light to generate the plurality of active pixel values.
