Warped Preview for Image Capture Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small display sizes in image capture devices make it difficult for users to determine framing and composition of visual content, especially when capturing wide-field views, as the reduced preview size complicates identifying details and proper framing.
Innovation Solution
The image capture device provides a warped preview on the display, where a portion of the visual content is enlarged, with the extent within this portion warped to increase size, allowing for better depiction and maintaining the rule of thirds, thus aiding users in framing and composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display size is kept small to maintain compact device form factor, then device portability is improved, but the ability to determine framing and composition of visual content deteriorates
Solution Approach 1:
The preview display is segmented into a normal preview area and an enlarged portion that displays a magnified view of a specific region of interest. This segmentation allows the small display to simultaneously show both the overall framing context and detailed composition information by dividing the display area into functional zones with different magnification levels.
Solution Approach 2:
The patent introduces an additional dimensional aspect to the preview display by adding the enlarged portion that provides depth through magnification. This creates a multi-scale viewing experience where users can observe both the global scene composition and local detail simultaneously, effectively adding a dimensional layer of information density to the limited display space.
2Area of stationary object
If the entire visual content is displayed at normal scale, then the complete scene context is preserved, but the ability to see detailed framing information deteriorates
Solution Approach 1:
The preview area is divided into segments: a normal-scale display showing the complete scene context and an enlarged portion displaying a magnified view of a specific region. This segmentation enables simultaneous preservation of both global context and local detail information without requiring additional display space.
Solution Approach 2:
Different regions of the display are assigned different quality characteristics - the main preview area maintains normal scale for context, while the enlarged portion provides enhanced detail quality through magnification. This local quality differentiation allows optimal information presentation in each display region based on its functional requirement.
3Measurement precision
If a portion of visual content is enlarged to improve framing visibility, then detail depiction is improved, but distortion of other portions may occur
Solution Approach 1:
The enlargement and warping effects are applied locally only to the specific region of interest in the enlarged portion, while the rest of the preview maintains its original undistorted appearance. This localized processing ensures that detail precision is enhanced where needed without introducing unnecessary distortion to other portions of the visual content.

AI summary
An image capture device may capture visual content through a front-facing optical element. A portion of the visual content may be enlarged for presenting on a front-facing display of the image capture device. Extent of the visual content within the portion may be warped to increases size of depiction within the portion.
