Display Control Apparatus Enlargement Area Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face difficulties in making the enlargement area easily recognizable and reducing the number of operations needed to provide an enlarged display, as current methods either require multiple operations or interfere with the visibility of the live view image.
Innovation Solution
A display control apparatus that stores information about the enlargement position and uses a processor to control the display, allowing for an immediate indication of the enlargement area without changing the display magnification and providing an enlarged display based on stored information, reducing the need for additional operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an index indicating the enlargement area is constantly superimposed and displayed on a live view image, then the enlargement area is easily recognizable, but the visibility of the live view image is interfered with
Solution Approach 1:
The index indicating the enlargement area is displayed periodically or temporarily rather than constantly. The display controller shows the index only when needed (when enlargement operation is detected or in progress), and hides it otherwise, creating a periodic display pattern that balances information provision with image visibility.
2Loss of information
If a live view image of actual size is displayed once and an index indicating an enlargement area is superimposed, then the enlargement area can be indicated, but the number of operations needed to provide an enlarged display increases
Solution Approach 1:
The indication of enlargement area and the provision of enlarged display are merged into a single continuous operation. Once the enlargement operation is started, the system maintains the index display and provides enlarged display without requiring the user to initiate separate operations, combining multiple functions into one operational flow.
Solution Approach 2:
The system performs preliminary actions by detecting the enlargement operation start and proactively displaying the index and preparing the enlarged display before the user would need to request it again. The system anticipates the user's need and executes the necessary display actions in advance.
3Loss of information
If angle of view frames corresponding to previous and next zoom steps are superimposed on a live view image, then the zooming range can be easily figured out, but the technique is limited to optical zooming with center enlargement
Solution Approach 1:
Instead of always displaying frames for the entire image or center area, the system displays the index and provides enlarged display for specific local areas that the user needs to examine. The enlargement position and area can be specified locally, allowing flexible focus on particular regions of interest rather than being constrained to center or full-image display.

AI summary
A display control apparatus to display a display object on a display unit includes a display control unit to perform control. In a case where a predetermined operation is started while the display object is displayed on the display unit at a first magnification, the display control unit performs control to provide a display indicating an enlargement area of the display object based on the information about the enlargement position stored in the storage unit without changing a display magnification of the display object and then provide an enlarged display of the enlargement area of the display object based on the information about the enlargement position stored in the storage unit, even without the predetermined operation being newly started. The enlarged display is enlarged at more than the first magnification.
