Further, the luminance changing unit determines a luminance after the change in a peripheral region of this bright region. A virtual-image creating unit creates a virtual image based on the determined luminance, and a display processing unit displays this virtual image on a display unit. In this manner, since a display system displays the virtual image for use in increasing the luminance in periphery of the bright region, the feeling of the brightness for the driver can be moderated, and therefore, the visual recognition can be improved. That is, the display system can output the virtual image depending on the circumstances. ## Claims ### Claim 1 A display system displaying a virtual image on a display mounted on a movable body, comprising: a camera configured to capture an exterior circumstantial image of a forward part of the movable body through the display; a memory configured to store an object including a letter and a symbol linked to the object; and a processing circuit configured to: determine a position of the movable body; determine a line-of-sight direction of a user based on at least one of position or direction of at least one of the user's head or the user's eyeball; determine an emphasis target from the exterior circumstantial image captured by the camera on the basis of the position of the movable body and the line-of-sight direction of the user; in response to the emphasis target being the object stored in the memory, create a symbol virtual image using the symbol stored in the memory corresponding to the object; and control the display so as to display the symbol virtual image at a position of the emphasis target. ### Claim 2 (depends on 1) The display system according to claim 1, wherein the processing circuit is further configured to: determine a luminance of the exterior circumstantial image captured by the camera; create a mask virtual image for masking a region of the exterior circumstantial image having a luminance that is greater than or equal to a threshold; and control the display so as to display the mask virtual image at a position of the region. ### Claim 3 (depends on 1) The display system according to claim 1, wherein the memory is further configured to store a relative-position based on a direction in which the exterior circumstantial image is captured by the camera and the line-of-sight direction of the user, the exterior circumstantial image and the symbol virtual image, as historical information. ### Claim 4 (depends on 1) The display system according to claim 1, wherein the object is a signboard. ### Claim 5 (depends on 1) The display system according to claim 1, wherein the movable body is a vehicle. ### Claim 6 A display apparatus comprising: a display; a memory configured to store an object and a symbol corresponding to the object; and a processing circuit configure to: acquire an exterior circumstantial image captured by a camera; acquire position information of the display apparatus; determine a line-of-sight direction of a user of the display apparatus based on at least one of position or direction of at least one of the user's head or the user's eyeball; determine an emphasis target from the exterior circumstantial image on the basis of the position information and the line-of-sight direction of the user; in response to the emphasis target being the object stored in the memory, create a symbol image using the symbol stored in the memory corresponding to the object; and control the display so as to display the symbol image at a position of the emphasis target. ### Claim 7 (depends on 6) The display apparatus according to claim 6, wherein the processing circuit is further configured to: determine a luminance of the exterior circumstantial image; create a mask image for masking a region of the exterior circumstantial image having a luminance that is greater than or equal to a threshold; and control the display so as to display the mask image at a position of the region. ### Claim 8 (depends on 6) The display apparatus according to claim 6, wherein the memory is further configured to store a relative-position based on a direction in which the exterior circumstantial image is captured by the camera and the line-of-sight direction of the user, the exterior circumstantial image and the symbol image, as historical information. ### Claim 9 (depends on 6) The display apparatus according to claim 6, wherein the object is a signboard. ### Claim 10 (depends on 6) The display apparatus according to claim 6, wherein the display apparatus is a head-up display or a head mounted display. ### Claim 11 (depends on 6) The display apparatus according to claim 6, wherein the display apparatus is mounted on a vehicle, the memory is further configured to store map information, and the processing circuit is further configured to determine a position of the vehicle by using the position information and the map information.
