A display device including: a timing unit configured to time an elapsed time from a starting time point; a display control unit configured to control a display of a displayed image and an information image including a display related to the elapsed time; and a time setting unit configured to set a presentation time. The display control unit exerts control such that the display of the information image is displayed over the presentation time, and changes a mode of the information image whenever an elapsed time timed by the timing unit reaches a set time. ## Claims ### Claim 1 A display device comprising: a timing unit configured to time an elapsed time from a starting time point; a display control unit configured to control a display of a displayed image and an information image including a display related to the elapsed time; and a time setting unit configured to set a presentation time, wherein the display control unit exerts control such that the display of the information image is displayed over the presentation time, and changes a mode of the information image whenever an elapsed time timed by the timing unit reaches a set time. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the set time is set at a certain time interval. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the set time is set every first time interval before a predetermined time elapses, and is set every second time interval which is shorter than the first time interval after a lapse of the predetermined time. ### Claim 4 (depends on 1) The display device according to claim 1, wherein changing, by the display control unit, the mode of the information image includes enlarging the information image. ### Claim 5 (depends on 1) The display device according to claim 1, wherein changing, by the display control unit, the mode of the information image includes changing a shape of the information image. ### Claim 6 (depends on 1) The display device according to claim 1, wherein changing, by the display control unit, the mode of the information image includes changing a display position of the information image. ### Claim 7 (depends on 1) The display device according to claim 1, wherein changing, by the display control unit, the mode of the information image includes changing a color of the information image. ### Claim 8 (depends on 1) The display device according to claim 1, wherein the information image includes a first image related to a first time unit and a second image related to a second time unit which is shorter than the first time unit. ### Claim 9 (depends on 8) The display device according to claim 8, wherein the first image and the second image are different in display form. ### Claim 10 (depends on 9) The display device according to claim 9, wherein the first image is a number, and the second image is a pie chart. ### Claim 11 (depends on 1) The display device according to claim 1, further comprising: an image acquisition unit configured to acquire the displayed image from an external device; and a projection unit configured to project the display device and the information image.
