Augmented reality providing apparatus

An augmented reality providing apparatus provided with an image capturing unit that captures an image for each frame period, comprising:

• a global coordinates calculation unit that calculates global coordinates indicating a position on which a virtual object is required to be superimposed in a global coordinate system that defines a virtual space corresponding to a real world, based on a reality image obtained with an image capturing by the image capturing unit;
• a virtual image combining unit that generates a virtual combined image in which a virtual object image is combined with the reality image using the global coordinates calculated from the global coordinates calculation unit;
• a display unit that displays any one of the reality image and the virtual combined image;
• a movement amount detection unit that detects an amount of movement of the augmented reality providing apparatus;
• and
• an output control unit that
• in a first frame period in which a reliability of the global coordinates calculated by the global coordinates calculation unit is equal to or greater than a first threshold and the amount of movement detected by the movement amount detection unit is equal to or less than the second threshold, performs a normal output control that causes the virtual combined image generated by the virtual image combining unit in the first frame period to be output to an external display device provided externally, and
• in a second frame period in which the reliability of the global coordinates becomes lower than the first threshold or the amount of movement becomes larger than the second threshold, performs a hold output control that causes the previous virtual combined image having been previously generated and stored by the virtual image combining unit in a frame period prior to the second frame period to be output to the external display device provided externally.
