A vehicular display apparatus comprising: a map data storage unit in which road information of a preset area is stored; a superimposition image information storage unit in which at least ones of captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle or processed images generated to correspond to the captured images are stored to be associated with the road information stored in the map data storage unit; a vehicle position detection unit configured to detect a position of the vehicle; a vehicle travel direction detection unit configured to detect a travel direction of the vehicle; a normal image capture unit configured to capture an image of a periphery of the vehicle; a superimposed area setting unit configured to set a superimposed area having a clarity lower than a preset clarity threshold in the image captured by the normal image capture unit; a superimposition image extraction unit configured to extract a superimposition image on a basis of the position of the vehicle detected by the vehicle position detection unit, the travel direction of the vehicle detected by the vehicle travel direction detection unit, the road information stored in the map data storage unit, among the images stored in the superimposition image information storage unit, the superimposition image being an image of a range corresponding to the image captured by the normal image capture unit; an image superposition unit configured to generate a superimposed image, by superimposing the image in an area corresponding to the superimposed area set by the superimposed area setting unit in the superimposition image extracted by the superimposition image extraction unit, on the image captured by the normal image capture unit; and an image display unit configured to display a video generated from the superimposed image generated by the image superposition unit at a position visible from a driver of the vehicle; characterized in that the superimposed area setting unit is further configured to detect a low gradation area where a gradation is lower than a preset gradation threshold, in the image captured by the normal image capture unit, and to set the detected low gradation area as the superimposed area. a map data storage unit in which road information of a preset area is stored; a superimposition image information storage unit in which at least ones of captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle or processed images generated to correspond to the captured images are stored to be associated with the road information stored in the map data storage unit; a vehicle position detection unit configured to detect a position of the vehicle; a vehicle travel direction detection unit configured to detect a travel direction of the vehicle; a normal image capture unit configured to capture an image of a periphery of the vehicle; a superimposed area setting unit configured to set a superimposed area having a clarity lower than a preset clarity threshold in the image captured by the normal image capture unit; a superimposition image extraction unit configured to extract a superimposition image on a basis of the position of the vehicle detected by the vehicle position detection unit, the travel direction of the vehicle detected by the vehicle travel direction detection unit, the road information stored in the map data storage unit, among the images stored in the superimposition image information storage unit, the superimposition image being an image of a range corresponding to the image captured by the normal image capture unit; an image superposition unit configured to generate a superimposed image, by superimposing the image in an area corresponding to the superimposed area set by the superimposed area setting unit in the superimposition image extracted by the superimposition image extraction unit, on the image captured by the normal image capture unit; and an image display unit configured to display a video generated from the superimposed image generated by the image superposition unit at a position visible from a driver of the vehicle; characterized in that the superimposed area setting unit is further configured to detect a low gradation area where a gradation is lower than a preset gradation threshold, in the image captured by the normal image capture unit, and to set the detected low gradation area as the superimposed area.
