IMAGE CALIBRATION METHOD AND DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18257263 titled 'IMAGE CALIBRATION METHOD AND DEVICE

Simplified Explanation

The patent application describes a method and device for calibrating images displayed on a head-mounted display device based on the user's pupil position offset and visual acuity. The pupil position offset refers to the deviation of the user's pupil from the optical axis.

  • Obtaining the pupil position offset and visual acuity of the user.
  • Adjusting the image to be displayed based on the pupil position offset and visual acuity.
  • Ensuring that the center point of the displayed image aligns with the user's point of focus when wearing the head-mounted display device.

Potential applications of this technology:

  • Virtual reality (VR) and augmented reality (AR) headsets: This calibration method can enhance the user's viewing experience by ensuring accurate image alignment and focus, reducing eye strain, and improving visual clarity.
  • Medical imaging: The method can be used in medical imaging devices, such as surgical microscopes or endoscopes, to calibrate the displayed images according to the user's pupil position and visual acuity, allowing for precise visualization during procedures.

Problems solved by this technology:

  • Improper alignment of displayed images: When users wear head-mounted display devices incorrectly, the center point of the displayed image may not align with their point of focus, leading to discomfort and reduced visual clarity. This technology solves this problem by adjusting the image based on the user's pupil position offset.
  • Eye strain and visual fatigue: Inaccurate image alignment can cause eye strain and visual fatigue, especially during prolonged use of head-mounted display devices. By calibrating the image based on the user's visual acuity, this technology helps reduce these issues.

Benefits of this technology:

  • Enhanced user experience: By ensuring accurate image alignment and focus, users can have a more immersive and comfortable experience when using head-mounted display devices.
  • Improved visual clarity: The calibration method takes into account the user's visual acuity, resulting in sharper and clearer images.
  • Reduced eye strain and fatigue: Proper image alignment and focus help reduce eye strain and visual fatigue, allowing users to use head-mounted display devices for longer periods without discomfort.


Original Abstract Submitted

An image calibration method and a device are provided. The method includes: obtaining a pupil position offset of a user and a visual acuity of the user, where the pupil position offset of the user is an offset of a pupil of the user relative to an optical axis; and adjusting a to-be-displayed image based on the pupil position offset of the user and the visual acuity of the user. In this way, when the user wears a head-mounted display device improperly, a point seen by the user when the user looks straight ahead is a center point of an image displayed on a display.
