9. An electronic terminal device using a touch pen, the electronic terminal device comprising: a touch screen device configured to display an execution screen of an application in response to the application being executed; and a processor configured to: in response to a handwriting image being input on an area of a handwriting input layer by the touch pen, determine a data type to recognize the handwriting image based on an area in which the handwriting image is input among a plurality of areas of the handwriting input layer; recognize the handwriting image as the determined data type; and apply the recognized handwriting image to the executed application differently according to the determined data type of the handwriting image, wherein the handwriting input layer overlaps with the execution screen of the application, and the processor is further configured to: determine the data type for recognizing the handwriting image as a text in response to the handwriting image being input in a first area among the plurality of areas of the handwriting input layer, and determine the data type for recognizing the handwriting image as an image in response to the handwriting image being input in a second area different from the first area among the plurality of areas of the handwriting input layer.
9. An electronic terminal device using a touch pen, the electronic terminal device comprising: a touch screen device configured to display an execution screen of an application in response to the application being executed; and a processor configured to: in response to a handwriting image being input on an area of a handwriting input layer by the touch pen, determine a data type to recognize the handwriting image based on an area in which the handwriting image is input among a plurality of areas of the handwriting input layer; recognize the handwriting image as the determined data type; and apply the recognized handwriting image to the executed application differently according to the determined data type of the handwriting image, wherein the handwriting input layer overlaps with the execution screen of the application, and the processor is further configured to: determine the data type for recognizing the handwriting image as a text in response to the handwriting image being input in a first area among the plurality of areas of the handwriting input layer, and determine the data type for recognizing the handwriting image as an image in response to the handwriting image being input in a second area different from the first area among the plurality of areas of the handwriting input layer. 11. The electronic terminal device of claim 9 , wherein the application is an application that displays a web screen provided by a server which is positioned outside the electronic terminal device, wherein the processor is further configured to determine the data type input in a component of a hypertext markup language (HTML) document in an area of the web screen as the data type to recognize the input-handwriting image, and recognize the handwriting image as the determined data type.
