A portable terminal is configured to perform a method for feature recognition. The portable terminal includes a Global Positioning System (GPS), a camera, a sensor, an image geographic information part, an image processor, and a controller. The GPS provides a position of the portable terminal. The camera photographs an image of a feature. The sensor detects a direction of the camera. The image geographic information part stores an image of each feature and geographic information on each feature. The image processor extracts a characteristic of the image of the feature and compares the extracted characteristic with image information stored in the image geographic info illation part. If recognizing a specific feature through the image processor, the controller proportionally compares geographic information of the image geographic information part with size and direction data on a peripheral feature near the specific feature within an image, and recognizes the peripheral feature.
