1. An information processing device comprising: an image capturing device that optically captures an image; a display device that displays a translation image on a screen; an input device that receives an input of a user; and at least one processor that: controls the display device to display the image captured by the image capturing device; translates, into another language, a text string contained in the image captured by the image capturing device; generates the translation image which is an image showing a result of translation of the text string; controls the display device to display the translation image corresponding to the text string such that the translation image is superimposed on the text string and that the text string is hidden by the translation image; in response to the user selecting a portion of the translation image, switches between a display by the display device of the portion of the translation image so that a corresponding portion of the text string is hidden, and a non-display by the display device of the portion of the translation image so that the corresponding portion of the text string is not hidden; and controls the display device to display a GUI (graphical user interface) that receives the input of the user to control the processor to switch between the display and the non-display of the portion of the translation image.
