Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display systems in digital cameras and video cameras do not adequately meet user demands for composition aids, as pre-set water levels and auxiliary lines are insufficient for capturing diverse subjects, particularly those with curved lines or requiring precise composition.

Innovation Solution

A display control apparatus and method that allows users to dynamically control and customize the display of auxiliary lines on a screen in real-time based on user input, enabling the drawing and adjustment of lines to suit specific composition needs during image capturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pre-set water levels and auxiliary lines are used, then the device complexity is reduced and ease of operation is improved, but the adaptability to different subjects and composition needs deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidadaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The auxiliary line system transitions from static pre-set configurations to dynamic user-customizable lines. Users can draw auxiliary lines freely on the screen, and the system dynamically adjusts the display to show these custom lines, enabling adaptation to various composition needs while maintaining simple operation through touch interface

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The auxiliary line function serves multiple purposes: it can be used for horizontal/vertical alignment, curved line composition, subject framing, and various creative compositions. A single auxiliary line system replaces multiple pre-set patterns, providing universal applicability across different shooting scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If pre-set auxiliary lines are used, then the device complexity is reduced, but the manufacturing precision and measurement precision for composition aid deteriorates

Engineering Contradiction:

Improvedevice complexityVSAvoidprecision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The system allows continuous adjustment of auxiliary line parameters including position, shape (straight or curved), length, and orientation. Users can precisely position auxiliary lines by touching and dragging on the screen, enabling high precision composition aid without complex mechanical structures

Inventive Principle:

Principle #35Parameter changes
