Abstract: An apparatus and a method for recognizing an object in an image are disclosed. The method for recognizing an object in an image may include: executing a deep neural network algorithm which has been trained in advance to recognize an object in an image, on a first image inputted from a camera module; finding an amount of change in image between the first image and a second image inputted from the camera module after the first image according to a predetermined cycle; and in response that an object has been detected from the first image as a result of executing the deep neural network algorithm, tracking the position of the detected object from the second image, based on the found amount of change in image.
