==VIEWFINDER UNIT WITH LINE-OF-SIGHT DETECTION FUNCTION, IMAGE CAPTURING APPARATUS, AND ATTACHMENT ACCESSORY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17837566 titled 'VIEWFINDER UNIT WITH LINE-OF-SIGHT DETECTION FUNCTION, IMAGE CAPTURING APPARATUS, AND ATTACHMENT ACCESSORY

==Simplified Explanation==

The patent application describes a viewfinder unit that includes an optical member, a display, an eyepiece, an illuminator, a sensor, a detector, and an opening wider than the display area.
* The optical member is held by a first member in a direction orthogonal to its optical axis.
* The illuminator is positioned inside the opening and outside the display area when the eyepiece is viewed in the optical axis direction.
* A portion of the optical member extends into the opening in the orthogonal direction.
* The illuminator and the second member are located within a second area surrounded by the outline of the first member and the first area of the optical member.

Potential applications of this technology:
* Camera viewfinders
* Virtual reality headsets
* Augmented reality devices

Problems solved by this technology:
* Provides a clear and well-illuminated view of the display through the eyepiece
* Ensures accurate detection of the photographer's eye proximity to the eyepiece

Benefits of this technology:
* Improved visibility and clarity of the displayed content
* Enhanced user experience and comfort while using the viewfinder
* Accurate detection of eye proximity for efficient operation and power management


==Original Abstract Submitted==

A viewfinder unit includes an optical member between a display and an eyepiece, a first member holding the optical member in a direction orthogonal to an optical axis of the optical member, an illuminator, a second member holding the illuminator, a sensor picking up a photographer's eye image, a detector detecting proximity of the eye to the eyepiece, and an opening wider than a display area of the display in the optical axis direction. When the eyepiece is viewed in the optical axis direction, the illuminator is inside the opening and outside the display area. Part of a first area of the optical member, projecting from an outline of the first member in the optical axis direction, is inside the opening in the orthogonal direction, and at least one of the illuminator and the second member is in a second area surrounded by the outline and the first area.
