Method and device for providing augmented reality image and recording medium storing program to execute the method

A method of providing, by a device, an augmented reality (AR) image, the method comprising:

• obtaining a first image including an object at an object position and a second image including a mask for blocking transmission of light incident on a display of the device at the object position;
• determining a time period;
• predicting blur values of pixels corresponding to the mask of the second image based on a distance between the display and a user of the device, a pupil size of the user, and a focal distance of the device;
• performing preprocessing on the second image to offset a blur effect of the second image based on the predicted blur values;
• generating a corrected second image based on the predicted blur values;
• and
• controlling a display to alternately display the first image and the corrected second image during the time period,
• wherein a polarization switch included in the device is configured to alternately polarize light incident on the display at a switching period determined based on the determined time period.

A non-transitory computer-readable recording medium storing a program, which when executed by a processor of an augmented reality (AR) device, causes the AR device to perform an AR method, the AR method including:

• obtaining a first image including an object at an object position and a second image including a mask for blocking transmission of light incident on a display of the AR device at the object position;
• determining a time period;
• predicting blur values of pixels corresponding to the mask of the second image based on a distance between the display and a user of the AR device, a pupil size of the user, and a focal distance of the AR device;
• performing preprocessing on the second image to offset a blur effect of the second image based on the predicted blur values;
• generating a corrected second image based on the predicted blur values;
• and
• controlling a display to alternately display the first image and the corrected second image during the time period,
• wherein a polarization switch included in the AR device is configured to alternately polarize light incident on the display at a switching period determined based on the determined time period.
