Head-Mount Display Live View Transparency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-angle photography, it is challenging for users to capture moving subjects as the line of sight for viewing a live view image and the subject are apart, making it difficult to place the subject within the image frame and confirm the captured image.
Innovation Solution
An image capturing system that includes a head-mount type display device, where a live view image and operation information are transmitted from an image capturing apparatus to a display device, allowing the display device to control the display of the image based on the received information, adjusting transparency and size to facilitate easier subject placement and image confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the transparency of the live view image is increased, then the user can view the actual scene through the image, but it becomes difficult to distinguish the live view image from the actual scene
Solution Approach 1:
The patent applies color changes by superimposing a colored filter (such as a red or blue filter) on the live view image displayed on the transmissive display section. This color overlay allows the user to distinguish the live view image from the actual scene while maintaining high transparency for viewing the actual scene through the display.
Solution Approach 2:
The patent uses composite materials by combining the live view image with a colored filter layer to create a composite visual output. This composite approach allows the live view image to remain translucent for scene visibility while the added color component provides clear distinction and frame recognition.
2Loss of information
If the transparency of the live view image is decreased, then the image frame becomes more distinguishable, but the actual scene behind the image is hidden
Solution Approach 1:
By applying a colored filter to the live view image, the patent achieves both distinguishability of the image frame and maintains visibility of the actual scene. The color overlay provides visual contrast that defines the frame boundaries while the underlying translucent image still allows light from the actual scene to pass through.
Solution Approach 2:
The patent employs dynamics by allowing the user to adjust the transparency level of the live view image according to different shooting conditions. The transparency can be changed dynamically to optimize the balance between frame distinguishability and actual scene visibility based on the specific photography situation.
3Adaptability or versatility
If a variable angle type display section is used for live view, then the display can be viewed from different angles, but the line of sight for viewing the live view image and the subject are apart
Solution Approach 1:
The patent uses the user's eye as an intermediary by projecting the live view image directly onto the user's retina through the transmissive display section positioned in the visual field. This eliminates the need for the user to shift their line of sight to a separate display, as the image is superimposed directly on what they are already viewing.
Solution Approach 2:
The patent transitions from a two-dimensional separate display to a three-dimensional spatial overlay by projecting the live view image into the user's visual field space. This dimensional change allows the image to be viewed at the same spatial location as the actual scene, aligning the line of sight without requiring angle adjustment.

AI summary
An image capturing system including an image capturing apparatus and a head-mount type display device. A smartphone which is the image capturing apparatus generates a live view image and transmits the live view image and operation information associated with an operation performed on the smartphone to a smart glass which is the display device. The smart glass includes a display section and receives the live view image and the operation information from the smartphone. An image generation unit of the smart glass generates a display image to be displayed on the display section, based on the received live view image, and the generated display image is displayed on the display section. The image generation unit changes the display image to be displayed on the display section, according to the received operation information.
