Processor, display control method, and display control program

A display control method comprising:

• via a processor included in a glasses-type display device that allows at least one eye of a user to visually recognize a real space and that displays a captured image obtained by imaging the real space with a camera,
• performing display processing of displaying a partial image, which is a partial region of the captured image captured by the camera, in a manner visually recognizable by the user based on a parallax between the eye of the user and the camera,
• performing display processing, including cancelling a misregistration amount β corresponding to a distance between a position of a subject image in a real image and a position of a subject image in the captured image,
• wherein the processor performs display processing, including cutting out a partial region from the captured image as a partial image so as to cancel the misregistration amount β, and wherein the misregistration amount β is derived according to the following equation;
• β=α×(F÷D), where F is a focal length of the camera, D is a distance between the camera and a subject, and α is the parallax between the eye of the user and the camera.

A non-transitory storage medium storing a display control program causing a processor, which is included in a glasses-type display device that allows at least one eye of a user to visually recognize a real space and that displays a captured image obtained by imaging the real space with a camera, to execute a process comprising:

• performing display processing of displaying a partial image, which is a partial region of the captured image captured by the camera, in a manner visually recognizable by the user based on a parallax between the eye of the user and the camera,
• performing display processing, including cancelling a misregistration amount β corresponding to a distance between a position of a subject image in a real image and a position of a subject image in the captured image,
• wherein the processor performs display processing, including cutting out a partial region from the captured image as a partial image so as to cancel the misregistration amount β, and
• wherein the misregistration amount β is derived according to the following equation:
• β=α×(F÷D), where F is a focal length of the camera, D is a distance between the camera and a subject, and α is the parallax between the eye of the user and the camera.
