Dynamic Blur Effect for Wide-Angle Visual Content

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wide-angle image capture often results in distorted views that are difficult to present effectively on displays, leading to a need for systems and methods that can enhance blurriness at the periphery of the field-of-view to draw attention to central content.

Innovation Solution

A system comprising physical processors configured by machine-readable instructions to modify visual content by increasing blurriness, particularly at the periphery of the field-of-view, using techniques such as pixel-based processing and transformations to create directional blur or mimic optical aberration, while maintaining sharpness at the center.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If wide-angle image capture is used to expand field-of-view, then the area of visual content is improved, but the manufacturing precision of the image quality deteriorates due to distortion

Engineering Contradiction:

Improvefield-of-viewVSAvoidimage quality

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies different quality levels to different regions of the image: the central region maintains sharp, high-quality focus while the peripheral regions apply increasing blur. This resolves the contradiction by preserving image quality where it matters most (center) while accepting degraded quality in less important areas (periphery) to enable wider field-of-view capture.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The image is segmented into multiple regions (central region and peripheral regions) with different blur characteristics. The central region remains sharp while peripheral regions are progressively blurred, allowing the system to capture wide-angle content while maintaining acceptable quality in the important central area.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If wide-angle image capture is used to expand field-of-view, then the area of visual content is improved, but the manufacturing precision of the image quality deteriorates due to distortion

Engineering Contradiction:

Improvefield-of-viewVSAvoidimage quality

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

Instead of applying blur uniformly across the entire image, the patent applies blur only partially to the peripheral regions while keeping the central region sharp. This partial action allows the system to achieve wide field-of-view capture without sacrificing the quality of the most important central content.

Inventive Principle:

Principle #16Partial or excessive action

3Ease of operation

If blur is applied to periphery to draw attention to center, then the ease of operation for focusing attention is improved, but the loss of information in peripheral areas increases

Engineering Contradiction:

Improveattention focusVSAvoidperipheral content

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent converts the harmful effect of information loss in peripheral areas into a beneficial attention-guiding mechanism. By intentionally blurring peripheral regions, the system draws viewer attention to the central content, transforming the loss of peripheral detail into a useful focus-directing feature that improves overall viewing experience.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Systems and method to increase blurriness of visual content may be based on user control, field-of-view, and/or changes in field-of-view. By adding or increasing blurriness at the periphery of the field-of-view, more attention may be drawn to unblurred sections.
