1. A translation display device comprising: a processor and an associated memory; wherein the processor: sequentially obtains images; performs a translation process of translating text extracted from any given image, and subjects a certain image to the translation process in a case where the certain image is obtained while no image other than the certain image is being subjected to the translation process; and identifies movement information indicative of a displacement of a position of an object in a most recent image which has been most recently obtained, the displacement being measured with respect to a reference position of an object in a reference image for which the translation process most recently ended; and the translation display device further includes a display that displays a generated image in which translated text obtained by translating extracted text extracted from the reference image is superimposed on the most recent image in accordance with (i) a position of the extracted text and (ii) the movement information, and a sensor that detects a movement of a camera, wherein the processor obtains an image captured by the camera, and in a case where a value concerning the movement of the camera with respect to a reference state of the camera at a time point at which the reference image was captured by the camera exceeds a predetermined range, (i) the processor does not identify movement information and (ii) the display displays the image obtained by the processor while the image has not been subjected to any process after being obtained.
