Abstract: Provided is a display device including a photographic image acquisition unit that acquires data regarding a photographic image to be displayed, a plurality of singular point detection units that each determine whether or not an allocated target pixel in the photographic image is a singular point which has an abnormal value, a plurality of correction units that each correct a pixel value by using values of adjacent pixels when the allocated target pixel is the singular point, and an output unit that outputs data regarding an image in which a pixel value of the singular point has been corrected, to a display panel.

Abstract: Disclosed is a head-mounted display including a captured image acquisition section that acquires data of an image captured by a camera mounted on the head-mounted display, a display image generation section that displays the captured image on a projection plane set in a virtual three-dimensional space as a display target and draws an image obtained when the captured image is viewed from a virtual camera, to generate a display image including the captured image, a projection plane controlling section that changes the projection plane according to a situation, and an outputting section that outputs the display image.

Abstract: Disclosed is a head-mounted display implementing stereoscopic vision, including a superimposition image controlling section that determines a virtual distance of a superimposition image to be displayed, according to a state of a three-dimensional space in a field of view, a display image generation section that generates data of a display image including the superimposition image in a state in which the superimposition image is placed at the virtual distance in the three-dimensional space, and an output controlling section that outputs the data of the display image to a display panel.
