Imaging Device Autofocus Area Alignment for Miniature Faking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in achieving precise miniature faking photography effects in digital images due to challenges in setting and maintaining the focus area and blurring area, leading to an inconsistent and often out-of-focus miniature scale model appearance.
Innovation Solution
An imaging device and method that automatically sets the autofocus area to overlap with the main area, allowing for a seamless blurring operation on areas outside the main subject, ensuring proper focus and blurring settings during the miniature faking photography process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the autofocus area is manually set separately from the main area, then the user can control focus independently, but the alignment between focus area and main subject becomes inconsistent leading to imprecise miniature faking effects
Solution Approach 1:
The patent merges the autofocus area setting with the main area setting by automatically determining the autofocus area based on the detected main subject area. This eliminates the need for separate manual configuration of focus areas, ensuring precise alignment between the main subject and autofocus region while simplifying the user operation to only require main area selection.
2Reliability
If the blurring operation is performed on areas outside the main area, then the miniature faking effect is enhanced, but the autofocus area may not be properly aligned causing out-of-focus main subjects
Solution Approach 1:
The patent performs preliminary determination of the autofocus area based on the main area detection results before executing the blurring operation. By pre-aligning the autofocus area with the main subject area through automatic determination, the system ensures that the main subject remains in focus while areas outside the main area are blurred, thereby enhancing the reliability of the miniature faking effect without increasing system complexity.
3Manufacturing precision
If retouching software is used to perform miniature faking photography, then the effect can be achieved, but the processing becomes troublesome and time-consuming for users
Solution Approach 1:
The patent implements self-service functionality by automatically determining the autofocus area based on the main area detection, eliminating the need for users to manually configure focus settings or perform complex post-processing operations. The system autonomously aligns the focus area with the main subject and applies appropriate blurring to surrounding areas, thereby achieving precise miniature faking effects without requiring troublesome manual retouching operations or additional processing time.
