AI Technical Summary
Technical Problem
In head-mounted displays (HMDs), individual differences in eyepiece lenses for the left and right eyes cause varying magnifications, leading to positional misalignment and potential flickering or double images due to binocular rivalry, especially in higher image heights.
Method used
An image processing apparatus that acquires stereo images and corrects the positional displacement between left and right eye views using image height displacement information, adjusting the correction amount for each region to reduce misalignment.
Benefits of technology
Reduces positional misalignment in stereo images observed through eyepieces, minimizing flickering and double images by correcting the stereo image data based on acquired displacement information.

Abstract
To reduce positional misalignment in stereo images observed through a lens. [Solution] The image processing device displays a UI for inputting image height misalignment information on the HMD by executing a program stored on the HDD. The image height misalignment information acquisition unit acquires image height misalignment information. The image input unit acquires stereo image data from the HDD or the like. Image height misalignment information is acquired by correcting the test pattern so that flickering and double images caused by misalignment when the user observes the test pattern displayed on the left and right displays of the HMD with both eyes are reduced. The image height misalignment correction unit performs image height misalignment correction on the acquired stereo image data, adjusting the correction amount for each region specified by image height so as to reduce the misalignment in the observed image seen on the HMD. The image output unit outputs the corrected stereo image data to the HMD.
