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. 15. The electronic terminal device of claim 9 , wherein in response to the area of the execution screen comprising a table comprising a plurality of cells, the processor is further configured to recognize the handwriting image as a command which selects at least one of the plurality of cells and, in response to a handwriting image being additionally input on the handwriting input layer using the touch pen, the processor is further configured to recognize the additionally input handwriting image as the text or the image to display the text or the image on at least one selected cell.
