Solution Overview

Problem

Existing image display apparatuses face challenges in efficiently capturing and outputting a wall surface image as a background, especially when the wall surface is contaminated, damaged, or obstructed, or when the distance between the electronic device and the image display apparatus is short, leading to a significant difference in perceived quality between the captured and actual wall surfaces.

Innovation Solution

An electronic device equipped with a camera, display, and processor that determines the size of the wall surface to be photographed based on the distance between the device and the image display apparatus, displays a guideline on the preview image to indicate the region to be captured, and adjusts the guideline size according to movement, allowing users to accurately capture and transmit the image for output on the image display apparatus, minimizing differences in perceived quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the electronic device is positioned close to the image display apparatus to capture the wall surface, then the captured image quality improves, but the guideline size on the preview image becomes too small for accurate positioning

Engineering Contradiction:
Improvewall surface capture accuracyVSAvoidguideline visibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The guideline size is made dynamic and adjustable based on the distance between the electronic device and the wall surface. When the device is close to the wall, the guideline automatically enlarges to remain visible and usable for positioning, while still capturing the correct wall surface area.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the guideline display parameter (size) based on the distance parameter. By detecting the distance between the device and wall surface, the guideline size is adjusted accordingly - larger when closer, smaller when farther - to maintain both visibility and capture accuracy.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the electronic device is positioned far from the image display apparatus, then the guideline size on the preview image increases for better visibility, but the captured wall surface image quality deteriorates

Engineering Contradiction:
Improveguideline visibilityVSAvoidwall surface capture accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The guideline size dynamically adapts to the shooting distance. When positioned far from the wall surface, the guideline automatically reduces in size to represent the correct capture area, ensuring that users capture the appropriate wall surface region while maintaining guideline visibility on the display.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system adjusts the guideline display parameter inversely to the distance parameter. As distance increases, guideline size decreases proportionally, maintaining the correct visual representation of the capture area regardless of device position.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a fixed guideline size is displayed on the preview image, then the device structure is simplified, but the capture accuracy varies with distance changes

Engineering Contradiction:
Improveguideline display systemVSAvoidwall surface capture accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

Instead of a fixed guideline size, the system implements a dynamic guideline that automatically adjusts its display size based on the detected distance between the electronic device and the wall surface. This ensures consistent capture accuracy regardless of device position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guideline size parameter is changed based on the distance parameter detected by the system. This automatic parameter adjustment maintains accurate wall surface capture representation without requiring complex manual calibration or adjustment mechanisms.

Inventive Principle:
Principle #35Parameter changes
