The display unit includes a tubular display whose directional range in which an image is displayed is larger than 180 degrees. The motion sensor detects an observer who observes the display. The region setting unit sets a first region visible from the observer and a second region different from the first region as regions on the display on the basis of a detection result of the motion sensor. The information generating unit generates main information displayed in the first region and illumination information regarding illumination light presented in accordance with the second region. ## Claims ### Claim 1 A display apparatus, comprising: a display unit including a tubular display whose directional range in which an image is displayed is larger than 180 degrees; a motion sensor that is configured to detect an observer who observes the tabular display; and at least one processor configured to: set a first region visible from the observer and a second region different from the first region as regions on the tabular display based on a detection result of the motion sensor; and generate main information displayed in the first region and illumination information regarding illumination light presented in accordance with the second region. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the at least one processor is further configured to set the first region based on a directional range of the tabular display that is visible from one eye of the observer and based on a congestion angle when seeing the tabular display with both eyes of the observer. ### Claim 3 (depends on 1) The display apparatus according to claim 1, wherein the tabular display configures a cylindrical surface on which the image is displayed, and provided that D denotes a diameter of the cylindrical surface, Lv denotes an observation distance from an axis of the cylindrical surface to an observation position, Le denotes a distance between left and right eyes of the observer, and θ denotes a display angle in a directional range that defines the first region, the at least one processor is further configured to calculate the display angle θ in accordance with Expression (1) below [ Formula ⁢ 1 ]  θ 2 = cos - 1 ( D 2 / Lv 2 + ( Le 2 ) 2 ) + tan - 1 ( L e 2 / Lv ) . Expression ⁢ ( 1 ) ### Claim 4 (depends on 1) The display apparatus according to claim 1, wherein the motion sensor is configured to detect a distance to the observer, and the at least one processor is further configured to set the first region in accordance with the distance to the observer. ### Claim 5 (depends on 1) The display apparatus according to claim 1, wherein the motion sensor is configured to detect a plurality of observers simultaneously, and the at least one processor is further configured to calculate a plurality of individual regions as regions on the tabular display
