Semi-Transparent Ornament Overlay for Camera Auto-Focusing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to adjust and predict the spatial relationship between an ornament image and a photographing object on a digital camera display, as the ornament image is often opaque, covering parts of the moving image and obscuring the object's position.
Innovation Solution
An image capturing apparatus with an auto-focusing device and a semi-transparent display that initially shows the ornament image overlaid on the captured image, allowing users to adjust the spatial relationship, and then switches to opaque display after focusing, ensuring clear visibility of the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the ornament image is displayed opaque on the display, then the ornament image is clearly visible and the composite image can be predicted, but the photographing object is obscured and the spatial relationship cannot be judged
Solution Approach 1:
The patent applies dynamics by changing the transparency state of the ornament image from opaque to semi-transparent during the photographing process. The control unit dynamically switches the display mode based on the focusing state: opaque when focusing is complete for clear prediction, and semi-transparent during focusing to maintain visibility of the photographing object and enable spatial relationship adjustment.
Solution Approach 2:
The patent changes the transparency parameter of the ornament image display. The display unit modifies the transparency level of the ornament image from 0% (opaque) to 50% (semi-transparent) based on the focusing status. This parameter change allows the system to switch between two display modes: one for clear ornament visibility and another for maintaining object visibility during adjustment.
2Difficulty of detecting and measuring
If the ornament image is displayed semi-transparently, then the photographing object remains visible and spatial relationship can be judged, but the ornament image becomes less distinct and prediction becomes difficult
Solution Approach 1:
The system dynamically adjusts the transparency parameter based on the photographing state. During the focusing process, the ornament image is displayed semi-transparently to enable spatial relationship adjustment. Once focusing is complete, the system switches to opaque display mode to provide clear ornament visibility for final prediction and composite image generation.
Solution Approach 2:
The patent applies preliminary action by displaying the ornament image semi-transparently during the focusing process, allowing users to adjust the spatial relationship before the final photograph is taken. This preliminary display mode enables users to verify the positioning accuracy before switching to opaque mode for the actual capture.
3Manufacturing precision
If the ornament image covers the moving image completely, then the composite image is clearly defined, but the user cannot see the covered portion of the moving image
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of different regions. The ornament image is displayed with different transparency levels in different contexts: semi-transparent during focusing to show underlying moving image details, and opaque after focusing for clear composite image definition. This allows the system to optimize visibility for each specific operational phase.

AI summary
An image capturing apparatus is provided having an auto-focusing device and an image displaying device. The auto-focusing device focuses a lens on a photographing object automatically. The image displaying device displays an input image which corresponds to the photographing object and is updated periodically in a display, and displays an ornament image which covers all or part of the circumference of the input image in the display. The image displaying device displays the parts of the input image superimposed by the ornament image before said auto-focusing device finishes focusing the lens on a photographing object due to the ornament image semi-transparency, and displays the ornament image superimposed with opaque on parts of the input image after said auto-focusing device has focused the lens on a photographing object.
