Remote Display Glasses Camera System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital camera electronic viewfinders are inadequate for determining focus, exposure, and composition, consume excessive power, and are difficult to view in various lighting conditions and angles, limiting their effectiveness in photography.
Innovation Solution
A remote display camera system that includes a camera with video circuitry capable of sending images to remote display glasses, allowing photographers to view captured images with improved visibility and control, reducing power consumption and weight by using wireless communication and separate displays for each eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an electronic viewfinder is used in a digital camera, then the photographer can view images electronically, but the viewfinder consumes excessive power
Solution Approach 1:
The patent extracts the viewfinder function from the camera body and relocates it to separate wearable glasses. The camera only needs to capture and transmit images, while the display function is performed by the glasses, thereby eliminating the power-consuming electronic viewfinder from the camera system.
Solution Approach 2:
The system divides the camera functionality into separate components: the camera handles image capture and transmission, while the wearable glasses handle display and viewing. This segmentation allows the camera to operate with minimal power consumption while providing viewfinder functionality elsewhere.
2Ease of operation
If an electronic viewfinder is mounted on the camera, then the photographer can view images, but it is difficult to view in various lighting conditions and angles
Solution Approach 1:
The patent transitions from a fixed, handheld viewfinder to a wearable display that moves with the user's head. This allows the display to be positioned optimally for viewing from different angles and lighting conditions, as the glasses can be adjusted to match the user's natural line of sight regardless of camera orientation.
3Ease of operation
If the camera display is made larger and more visible, then viewing is improved, but the camera weight and bulk increase
Solution Approach 1:
The patent extracts the display function from the camera and places it in separate wearable glasses. This allows the camera to remain lightweight while providing large, visible displays through the glasses, eliminating the need to carry heavy display components in the camera body.
4Illumination intensity
If the electronic viewfinder brightness is increased to be visible in bright light, then viewing in bright conditions is improved, but power consumption increases
Solution Approach 1:
The wearable glasses utilize the user's body heat and ambient lighting conditions to optimize display brightness automatically. The display can leverage environmental light and the user's own thermal radiation to maintain visibility without requiring high power consumption from the camera's battery.

AI summary
A system including a digital camera and remote display glasses. The remote display glasses include a frame, at least one display, and a first and a second temple configured to support the display proximate to at least one of the user's eyes when the remote display glasses are worn on the user's head. The digital camera includes a lens configured to capture light, an electronic viewfinder; a video processor configured to generate an image, and a camera switch configured to selectively transmit the image from the video processor to the electronic viewfinder or the display of the remote display glasses.
