Imaging Apparatus Orientation-Based Live View Display Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face difficulties in achieving accurate horizontal alignment of images when the camera is held in portrait orientation, as existing methods for visual confirmation using side-by-side enlarged live view images are ineffective in this orientation.
Innovation Solution
An imaging apparatus with an orientation detection unit and a control unit that switches between left/right and up/down 2-area enlargement displays based on the camera's orientation, allowing for easy adjustment of the tilt angle in both landscape and portrait orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If side-by-side enlarged live view images from left/right regions are displayed, then horizontal alignment is achieved in landscape orientation, but horizontal alignment cannot be achieved in portrait orientation
Solution Approach 1:
The display arrangement dynamically changes based on camera orientation. When the camera is rotated from landscape to portrait orientation, the system automatically switches from displaying two enlarged regions side by side (left/right) to displaying them one above the other (top/bottom). This dynamic adaptation ensures that the enlarged display always provides useful visual feedback for horizontal alignment regardless of the holding orientation.
Solution Approach 2:
The invention transitions the display arrangement from a horizontal dimension (side-by-side in landscape) to a vertical dimension (stacked in portrait). By changing the spatial dimension of the display arrangement according to orientation, the system maintains effectiveness of the enlarged view for alignment purposes in both landscape and portrait modes.
2Device complexity
If a fixed display arrangement is used, then the system is simple to implement, but it cannot accommodate different camera orientations effectively
Solution Approach 1:
The system uses orientation detection (via acceleration sensor or similar) to provide feedback about the camera's current orientation. Based on this feedback, the control unit automatically adjusts the display arrangement. This feedback mechanism enables adaptive behavior without requiring complex manual configuration or user intervention.
Solution Approach 2:
The display system is designed to serve multiple orientations universally. A single display control mechanism handles both landscape and portrait orientations by switching between two display patterns, making the system universally applicable to different holding positions without requiring separate control systems for each orientation.
3Measurement precision
If enlarged display is activated, then visual confirmation for alignment is improved, but the display space for other information is reduced
Solution Approach 1:
Instead of enlarging the entire live view display, the system selectively enlarges only specific regions (two particular areas) that are relevant for alignment confirmation. This partial enlargement approach provides sufficient visual detail for precision alignment while leaving the rest of the display area available for other information such as menu options, status indicators, and control elements.

AI summary
An imaging apparatus including a control unit configured to perform control to present a first 2-area enlargement display of displaying live view images captured by two imaging regions that are separated in a width direction while arranging them on a display unit if an orientation of the imaging apparatus is a first orientation, and present a second 2-area enlargement display of displaying live view images captured by two imaging regions that are separated in a height direction while arranging them on the display unit if the orientation of the imaging apparatus is a second orientation. The control unit is configured to perform control to end the first 2-area enlargement display based on the orientation of the imaging apparatus changed from the first orientation in a manner satisfying a predetermined condition when the first 2-area enlargement display is presented.
