As an example, in the case of fixing the line of sight to the medical image 530 and inputting data, an error may be generated by selecting an unexpected key. As another example, in the case of fixing the line of sight to the input unit 1601 and inputting the data, the image processing can be performed on the unintended image.

The input unit 1601 according to an embodiment outputs the medical image 510 and the keyboard image 520 together on a single screen. Therefore, since the user's line of sight is not dispersed, the user can input data so as to perform image processing accurately on the intended image. Here, the medical image 510 output to the input unit 1601 and the medical image 530 output to the display unit 1400 may be the same image or different images.

The input unit 1601 can select any one of the words included in the recommended word list 630 based on the user input. For example, the input unit 1601 can select a word using a spelling corresponding to a key selected by the user from the keys included in the keyboard image 620. [ If the user touched a key corresponding to "A", the input unit 1601 can select a word including "A" from the words included in the recommended word list 630. For example, the input unit 1601 can select a word having "A" as the first spelling among the words included in the recommended word list 630.

Accordingly, the user can easily identify a word selected by the input unit 1601 from among a plurality of words. The input unit 1601 may output a spell that the user selects (e.g., touches a key) among the keys included in the keyboard image 620 to one area 640 of the screen 600.

On the other hand, the image processing unit 1201 can add text to at least a part of the medical image 620 based on the user input, and the input unit 1601 can output the image added with the text. Here, the text includes not only spellings constituting characters, but also numerals, symbols, and the like. Hereinafter, examples in which the image processing unit 1201 adds text to a medical image and the input unit 1601 outputs an image in which text is added will be described with reference to FIGS. 7 to 8.
