Display Control Apparatus Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact digital cameras with reduced operating members face increased operational complexity due to multi-function assignments, leading to inconvenient mode changes and excessive user operations when switching between display modes.
Innovation Solution
A display control apparatus with a setting unit, mode changing unit, and disabling setting unit that allows users to customize and disable specific display modes, enabling sequential changes between enabled modes without requiring multiple button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display modes are provided to offer various display options, then adaptability is improved, but the number of operations required to change modes increases
Solution Approach 1:
The patent implements dynamic mode switching where the system automatically transitions between display modes based on real-time detection of shooting conditions (e.g., switching between LCD display and viewfinder display based on lighting conditions or shooting scenario). This dynamic adaptation eliminates manual mode changing operations while maintaining multiple display mode options, resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The system performs self-service by automatically selecting and switching between display modes without requiring user intervention. The camera's control unit autonomously determines the appropriate display mode based on detected shooting conditions and automatically executes the mode switch, thereby providing multiple adaptability options while requiring zero operations from the user
2Volume of moving object
If operating members are reduced to increase compactness, then device size is improved, but the number of operations to be performed by user increases
Solution Approach 1:
The patent implements multi-functionality by designing a single operating member (such as a mode dial or button) that controls multiple functions including display mode selection, shooting mode selection, and other camera settings. This universal control mechanism allows the camera to maintain compact size with reduced operating members while minimizing the number of operations required, as one component performs multiple roles that would otherwise require separate controls
3Ease of operation
If display mode changes are made sequential through button presses, then mode switching is achieved, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple display modes in advance and preparing the system to switch between them instantly. The control unit maintains readiness for mode switching by pre-loading mode parameters and detection algorithms, enabling immediate transition when switching is required rather than requiring sequential button presses, thereby reducing mode changing time while maintaining ease of operation

AI summary
An image pickup apparatus allows a user to select and set a desired item to be displayed together with an image with a few operations. The user selects a desired item to be displayed together with an image, and stores the selected item as a setting for a display mode. The user can arbitrarily change a plurality of display modes. Further, the user can disable one or a plurality of display modes among the display modes. Therefore, the user does not need to change the display mode to an undesired display mode during changing between the display modes.
