Digital Camera Display Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras with large display screens face the challenge of reduced grip space due to the screen's size, leading to partial image obstruction when held in the conventional horizontal posture, and struggle to adapt to changing postures for optimal image viewing.
Innovation Solution
A display controller that switches between two modes: in the taking mode, the image is displayed with the long side perpendicular to the screen, and in the reproducing mode, the image is rotated 90 degrees to match the screen's orientation, allowing for a larger display area and improved convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display screen is made larger to enhance visibility, then the display area is improved, but the grip space is reduced causing the hand to cover part of the display
Solution Approach 1:
The patent applies dynamics by making the display orientation adaptable rather than fixed. The display controller automatically rotates the display image based on the camera's posture detection, allowing the display to dynamically adjust between landscape and portrait orientations. This resolves the contradiction by enabling the full display area to be utilized while maintaining proper grip space, as the display adapts to the user's holding position whether horizontal or vertical
2Area of moving object
If the camera body is made horizontal type for conventional operation, then the display can show full images in reproducing mode, but the camera becomes less stable when held with one hand
Solution Approach 1:
The patent makes the camera system dynamic by incorporating posture detection capability that automatically identifies whether the camera is held horizontally or vertically. Based on this detection, the display controller automatically rotates the displayed image accordingly. This allows the camera to maintain full image display area while accommodating stable one-handed vertical holding, as the display adapts to the detected posture rather than requiring a fixed horizontal orientation
3Adaptability or versatility
If the display is fixed in a single orientation, then the device structure is simple, but the camera cannot adapt to changing postures for optimal image viewing
Solution Approach 1:
The patent implements dynamics by introducing automatic posture detection and corresponding display rotation control. The display controller detects the camera's holding posture (horizontal or vertical) and automatically rotates the display image to match. This provides full posture adaptability while keeping the system relatively simple, as the rotation is automatically controlled based on detection rather than requiring manual intervention or complex mechanical adjustment mechanisms

AI summary
A digital camera is provided with a vertically long camera body having an approximately rectangular solid shape. An LCD panel provided in a rear surface of the camera body is arranged such that longitudinal directions of the display screen and the camera body correspond to each other. The digital camera is operated through a touch panel provided in a lower portion of the display screen. In a taking mode, an image is displayed in a small size on an upper portion of the display screen. In reproducing, the camera body is rotated sideways by 90 degree. In a reproducing mode, display posture of the image is also rotated by 90 degree, and the image is displayed in a large size on the entire display screen.
