Adaptive Focus Frame Positioning in Enlarged Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses struggle to determine the optimal position for focus adjustment after enlarging an image, as the focusing area either remains fixed or moves undesirably when the enlargement position changes, lacking a clear indication of the appropriate focus adjustment position based on the situation.
Innovation Solution
A display control apparatus with a reception unit, switching unit, and display control unit that allows for movement of the enlarged area and switches between enlarged and entire display states, determining the focus adjustment position based on the moved enlarged area, ensuring the focus adjustment position is accurately displayed and updated accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the focusing area is moved according to the movement of the enlargement position, then the focus can be maintained on the currently viewed area, but the original main object may lose focus
Solution Approach 1:
The patent applies dynamics by making the focus frame position adaptive rather than fixed. The focus frame dynamically adjusts its position based on whether the user moves the enlargement position or performs focus adjustment operations during enlarged display. This resolves the contradiction by allowing the system to maintain focus on the current view when needed while preserving the original main object focus when the user intends to return to it.
2Loss of information
If the focusing area remains fixed after enlargement, then the original focus position is maintained, but the user cannot easily check focus on moved areas
Solution Approach 1:
The patent implements feedback by continuously monitoring user operations during enlarged display and adjusting the focus frame position accordingly. When the user moves the enlargement position or performs focus adjustment, the system provides visual feedback through the focus frame to indicate the current focus state, enabling the user to understand how focus will behave after exiting enlarged display mode.
3Measurement precision
If a focus adjustment operation is performed during enlarged display, then the focus can be precisely adjusted on the enlarged area, but the focus frame position determination becomes complex
Solution Approach 1:
The patent applies preliminary action by determining the focus frame position in advance based on the enlarged area position before the user exits enlarged display. This preparation ensures that when the user completes focus adjustment operations, the focus frame is already positioned correctly to maintain or switch focus as needed, simplifying the overall control logic while achieving precise focus adjustment.

AI summary
Control is performed so that when an enlarged display state of a captured image is switched to an entire display state, and in a case where a particular operation is performed in the enlarged display state, a display item regarding focus adjustment is displayed at a position which is determined according to an enlarged area after movement of the enlarged area based on a movement instruction to move the enlarged area given in the enlarged display state, and in a case where the particular operation is not performed in the enlarged display state, the display item regarding focus adjustment is displayed at a position unrelated to the movement of the enlarged area based on the movement instruction.
