Imaging Apparatus Orientation Detection and Image Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses display and record images in a mirror-reversed state, causing actual and recorded images to differ, with characters and objects appearing reversed, which can lead to confusion during framing and image interpretation.
Innovation Solution
Incorporating a detection unit to determine the orientation of the imaging apparatus and a control unit to rotate or correct images captured by the in-camera, ensuring they are displayed or recorded in a correct rotational state, either by rotating images by 180 degrees or adding rotational information when the apparatus is oriented vertically or horizontally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mirror image reversal is applied to display live view image, then ease of operation for framing is improved, but manufacturing precision of image orientation is worsened
Solution Approach 1:
The system dynamically switches between mirror image display mode and normal image display mode based on shooting mode. In self-shot mode, mirror image reversal is applied for ease of framing; in timelapse mode, normal image orientation is maintained for accuracy. The control unit adjusts the image processing in real-time according to the detected shooting mode, making the system adaptable to different operational requirements.
Solution Approach 2:
The system changes the image processing parameter (mirror image reversal application) based on the shooting mode. When shooting mode is self-shot, the parameter is set to apply mirror image reversal; when timelapse shooting is detected, the parameter is changed to disable mirror image reversal. This parameter change resolves the contradiction by allowing the system to optimize for either ease of operation or image orientation accuracy depending on the specific shooting scenario.
2Manufacturing precision
If normal image display without mirror reversal is used, then manufacturing precision of image orientation is improved, but ease of operation for framing is worsened
Solution Approach 1:
The system dynamically adjusts the image display mode based on the detected shooting mode. For timelapse shooting, the system maintains normal image orientation without mirror reversal to ensure accuracy in representing the actual scene. For self-shot mode, it switches to mirror image display to improve framing ease. This dynamic adjustment resolves the contradiction by contextually optimizing the display mode.
Solution Approach 2:
The control unit changes the image processing parameter (application of mirror image reversal) based on the shooting mode detection. When timelapse mode is detected, the parameter is set to preserve normal image orientation; when self-shot mode is detected, the parameter is changed to apply mirror reversal. This parameter switching mechanism allows the system to resolve the contradiction between image orientation accuracy and framing ease.
3Ease of operation
If mirror image reversal is applied, then ease of operation for camera operator is improved, but loss of information about actual image orientation is worsened
Solution Approach 1:
The system dynamically controls the application of mirror image reversal based on the detected shooting mode. In self-shot mode, mirror image reversal is applied to improve operator convenience. In timelapse mode, the system disables mirror image reversal to preserve the actual image orientation information. This dynamic control ensures that the appropriate level of information preservation is maintained based on the shooting context.
Solution Approach 2:
The control unit changes the image processing parameter (mirror image reversal application) based on shooting mode detection. When timelapse mode is detected, the parameter is set to preserve actual image orientation information; when self-shot mode is detected, the parameter is changed to apply mirror reversal for operator convenience. This parameter switching resolves the contradiction by contextually optimizing both operator convenience and information preservation.
4Manufacturing precision
If image rotation processing is added, then manufacturing precision of image orientation is improved, but device complexity is worsened
Solution Approach 1:
The control unit is segmented into distinct functional modules: detection unit for detecting shooting mode, determination unit for determining the appropriate display mode, and image processing unit for applying or not applying mirror image reversal. This segmentation allows the complex function of resolving orientation contradictions to be divided into manageable, independent components, reducing overall system complexity while maintaining high manufacturing precision.
Solution Approach 2:
The control unit acts as an intermediary between the image capture unit and the display unit, mediating the image processing based on detected shooting mode. It receives the captured image, determines the appropriate processing based on shooting mode, and outputs the processed image to the display unit. This intermediary role allows the system to maintain simplicity in individual components while achieving complex overall functionality through coordinated processing.

AI summary
An imaging apparatus (100) includes a first imaging unit (13), a second imaging unit (103) configured to image an object in an opposite direction from the first imaging unit, a detection unit (44) configured to detect an orientation of the imaging apparatus, and a control unit (50) configured to perform control for displaying an image captured by the first imaging unit and an image captured by the second imaging unit on a display unit (28) at the same time. The control unit performs control so that the image captured by the second imaging unit is displayed after being rotated if the detection unit detects that the orientation of the imaging apparatus is a predetermined orientation, in a case where the image captured by the second imaging unit is displayed together with the image captured by the first imaging unit without being reversed by a mirror image reversal.
