Multi-Plane Camera Projection for Individualized Depth of Field
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera imaging and projection systems fail to maintain depth of field effectively for individual users, particularly for closely spaced objects, due to the use of a single plane for image generation, leading to observational errors.
Innovation Solution
A camera projection system that includes a Camera, Camera Vehicle, Display Device, Viewing Space, Head unit to model eye coordinates, Field of View unit, Recapture Space, and Image Set to maintain and display images in a way that the viewer's focus point can be in front or behind the display surface, with the image focus point parallel to the retina plane, using Stereo and Mono Recapture Units to capture and display images on specific angles and orientations.

Engineering Contradiction Analysis
1Device complexity
If a single plane is used to generate an image, then the system complexity is reduced, but observational errors occur for closely spaced objects
Solution Approach 1:
The patent divides the single plane into multiple planes (first plane and second plane) positioned at different depths. The first plane displays images for distant objects while the second plane displays images for closely spaced objects, allowing each plane to be optimized for its specific depth range and eliminating observational errors without requiring a single complex plane to handle all depths.
Solution Approach 2:
The patent transitions from a two-dimensional single plane to a three-dimensional multi-plane arrangement by positioning planes at different depths along the optical axis. This dimensional extension allows the system to represent different depth zones simultaneously, improving observation accuracy for objects at various distances while maintaining manageable system complexity through modular plane design.
2Measurement precision
If individualized depth of field effects are implemented, then viewing accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent applies different optical properties and image characteristics to different planes based on their specific functions. The first plane is optimized for distant objects with appropriate focal characteristics, while the second plane is optimized for closely spaced objects with different focal characteristics. This local optimization achieves individualized depth of field effects without requiring the entire system to be redesigned with uniform complexity.
