Claim 0:
1. An Augmented Reality (AR) display apparatus to display an AR image, being image information on augmented reality, onto a screen transmitting an actual view of an external world, the AR display apparatus comprising:
a processor, which when executing a program, configures the processor to:
determine whether an object in an image photographed by a camera is a fixed object or a moving object, the fixed object being an object that does not move, the camera being configured to photograph an area including an actual view corresponding to a field of view of a user, the moving object being an object that is moving;
extract, in a case where the processor determines that the object is the fixed object, a pixel in an area of the fixed object with respect to a plurality of image frames;
obtain an amount of change in a position of the pixel extracted with respect to the plurality of image frames;
judge visibility of the user to the fixed object in the actual view of the external world viewed through the screen on a basis of the amount of change in the position of the pixel;
control the AR image regarding the fixed object;
calculate a moving direction of the fixed object on a basis of a difference between the area of the fixed object at a first point in time and the area of the fixed object a second point in time, the area of the fixed object changing in time series on the screen transmitting the actual view of the external world;
predict the area of the fixed object at a third point in time on a basis of the area of the fixed object at the second point in time and the calculated moving direction; and
display the AR image of the fixed object at a position different from the predicted area of the fixed object at the third point in time,
wherein the different position where the AR image is displayed is a position that does not overlap with a predicted movement trajectory of the area of the fixed object based on the moving direction,
wherein the different position where the AR image is displayed is temporally ahead in the moving direction,
wherein different positions that are positions where the AR image is displayed are selected as neighboring positions when following the area of the fixed object at the third point in time,
wherein the AR image is displayed with a selected position as a static position for a period of time including at least the third point in time, and
wherein the different position where the AR image is displayed is a position above the area of the fixed object at the third point in time when the predicted movement trajectory is a horizontal movement trajectory.
