1. A terminal for an integrated image search, comprising: a photographing device configured to create an object image by capturing a desired object; an image recognition unit configured to classify an object type of the object by analyzing the object image created using the photographing device; an integrated recognition engine comprising a plurality of decoders corresponding to various object types, and configured to decode the object image by driving, among the plurality of decoders, a decoder corresponding to the classified object type of the object, and make a request for searching for additional information about the decoded object information; and an interface unit configured to transmit object information decoded using the integrated recognition engine to an external apparatus connected over a communication network so as to send the request for searching for the additional information about the object information, and to receive a result of a search, wherein when a number of object types classified using the image recognition unit is greater than one, the integrated recognition engine is configured to search for decoder information having a recognition rate ranking with respect to the decoders, sequentially drive decoders corresponding to the classified object types, starting with a decoder having a highest recognition rate among the decoders corresponding to the classified object types, and provide the search result in a descending order of the recognition rate.
