Rotary Display Orientation Management for Preview Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses, such as image forming apparatuses, do not effectively manage the display of preview images when the display device is rotated between landscape and portrait orientations, leading to inconsistencies in image orientation and user instructions for job resumption or suspension.
Innovation Solution
The apparatus includes a control device that detects the orientation of the display device using a sensor and adjusts the display of preview images accordingly. When the display is rotated from landscape to portrait, the preview image is enlarged, and when rotated back, the user is prompted to resume or suspend the job through a dialog box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device is rotated from landscape to portrait orientation, then the preview image can be displayed in an enlarged size with expanded display region, but the image orientation may become inconsistent with the display orientation
Solution Approach 1:
The system dynamically adjusts the preview image orientation and display parameters based on the detected display device orientation. When portrait orientation is detected, the system rotates the preview image 90 degrees and expands the display region to utilize the vertical space effectively, maintaining visual consistency between image and display orientation.
Solution Approach 2:
The control device changes multiple parameters simultaneously when orientation change is detected: rotation angle of the preview image (0 or 90 degrees), display region boundaries (expanded in portrait mode), and image size (enlarged in portrait mode). These parameter changes ensure the preview image remains consistent with the display device orientation while maximizing the use of available display space.
2Manufacturing precision
If the preview image is enlarged when rotating to portrait orientation, then the display quality improves, but the job processing may be interrupted or suspended
Solution Approach 1:
The system performs preliminary detection of orientation changes and prepares the preview image transformation in advance. By detecting the portrait orientation before fully displaying the enlarged preview, the system can smoothly transition the image display without interrupting the underlying job processing operations, thus maintaining both display quality and processing continuity.
Solution Approach 2:
The system maintains continuous job processing while the preview image is being transformed and displayed in the new orientation. The image formation or copying job continues in the background while the control device simultaneously updates the preview display, ensuring that the useful action of job processing is not interrupted by the orientation change and image enlargement operations.
3Adaptability or versatility
If the display device supports both landscape and portrait orientations, then the adaptability to user preferences improves, but the device complexity increases due to the rotary mechanism and orientation detection
Solution Approach 1:
The display device performs self-detection of its own orientation through the integrated sensor, and the control device automatically adjusts all display parameters without requiring user input. The system serves itself by autonomously detecting orientation changes and adapting the preview image display accordingly, reducing the need for complex user interfaces or manual configuration while maintaining high adaptability.

AI summary
An image forming apparatus includes a rotary mechanism that allows a display device to rotate between a landscape orientation in which the long sides are opposed in an up-down direction, and a portrait orientation in which the short sides are opposed in the up-down direction, and a controller that displays a second preview screen, in which a preview image display region has been expanded, when the display device, displaying a first preview screen, has been shifted from the landscape orientation to the portrait orientation. When the display device is shifted from the portrait orientation to the landscape orientation, in a state where the second preview screen is displayed on the display device, and a job assigned with respect to image data corresponding to the second preview image is suspended, the controller displays a message urging inputting of an instruction on whether to resume the job, on the display device.
