Camera Assistance System Using 3D Sharpness Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera assistance systems for focusing cameras are either overly informative, obscuring the actual image content or not intuitive enough, making manual focusing tedious and prone to errors for users.
Innovation Solution
A camera assistance system that projects a camera image onto a virtual three-dimensional projection surface, where height values correspond to local imaging sharpness, allowing for intuitive focusing by displaying the image on a suitable display unit, potentially with 3D or pseudo-3D representations, and using contrast or phase detection units to enhance precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional camera assistance systems superimpose additional information on the camera image, then focusing assistance is provided, but the actual captured camera image becomes visible only to a limited extent
Solution Approach 1:
The patent transforms the two-dimensional camera image into a three-dimensional representation where height values correspond to local imaging sharpness. This dimensional transformation allows sharpness information to be visualized without obscuring the underlying image content, as the sharpness data is encoded in the vertical dimension rather than overlaying the horizontal plane of the image.
2Measurement precision
If conventional camera assistance systems use complex information displays, then focusing information is provided, but the display becomes not intuitively comprehensible to the user
Solution Approach 1:
The patent employs color coding to represent different levels of imaging sharpness in the three-dimensional projection. By assigning specific colors to different sharpness ranges, the system provides intuitive visual feedback that is easily comprehensible to users, allowing them to quickly identify in-focus regions without interpreting complex numerical data.
Solution Approach 2:
By projecting sharpness information into the vertical dimension, the patent creates an intuitive height-based representation where peaks indicate sharp regions and valleys indicate blurred regions. This spatial metaphor is naturally understandable to users, eliminating the need for complex legends or scales.
3Ease of operation
If manual focusing is performed without assistance, then the camera lens can be focused, but the process becomes tedious and prone to error
Solution Approach 1:
The patent implements real-time feedback by continuously analyzing the camera image and projecting sharpness information onto the three-dimensional surface. This immediate visual feedback allows users to adjust the focus and instantly see the effect on different regions of the image, enabling rapid convergence to the correct focus setting with minimal errors.
Solution Approach 2:
The patent replaces traditional mechanical focus indication methods (such as focus peaking or overlay planes) with a three-dimensional projection system that provides more comprehensive and intuitive feedback. This substitution transforms the focusing process from a trial-and-error mechanical adjustment to a guided visual process.
