Variable Magnification Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image processing apparatus requires users to frequently switch between modes to check image composition and focus state, leading to operational inefficiencies.
Innovation Solution
A variable-magnification image processing apparatus that allows users to select from predefined magnification settings for increasing or decreasing image display, enabling seamless transitions between composition and focus state checks without mode switching, using a magnification setting group, display magnification obtaining unit, and display control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus uses separate display modes for composition checking and focus checking, then the display can be optimized for each specific purpose, but the user must frequently switch modes which reduces operability
Solution Approach 1:
The patent merges composition checking and focus checking into a single display mode by integrating variable magnification control within the live view display. The magnification setting selection unit allows users to select from multiple discrete magnification settings (e.g., 1x, 2x, 5x, 10x) without switching display modes, thereby combining the functionality of separate composition and focus checking modes into one unified interface.
Solution Approach 2:
The live view display is designed to serve multiple functions simultaneously - it can display images at various magnification levels for both composition checking and focus state verification. The display control unit enables the same display interface to adapt to different checking needs through magnification adjustment, making the display system universal for both composition and focus evaluation tasks.
2Adaptability or versatility
If the apparatus provides multiple discrete magnification settings, then the user can select appropriate magnification for different checking needs, but the system complexity increases
Solution Approach 1:
The patent implements dynamic magnification control where the display magnification can be changed on-the-fly during live view display. The magnification setting selection unit allows users to dynamically switch between predetermined discrete magnification settings (1x, 2x, 5x, 10x) without requiring system reconfiguration or mode changes, providing adaptability while maintaining system simplicity through a unified control interface.
