Original Abstract Submitted

An image signal processor may include a data receiver configured to receive image data including depth values corresponding to pixels included in an image obtained from a distance measurement sensor. The image signal processor may also include a motion detector configured to detect motion in the image using either a first motion detection method which uses pixels or a second motion detection method which uses preset kernels, based on amplitude of the light source and generate a detection result indicating whether the motion is included in the target image. A noise remover removes noise from the target image using either a first noise removal method which uses previous image data corresponding to previous images or a second noise removal method which uses the image data corresponding to the target image based on the detection result.
