Image Forming Preview Rotation for Upright Character Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses struggle to display preview images with characters in a portrait orientation, making it difficult for users to decipher and recognize details, especially when the characters are in a landscape orientation.
Innovation Solution
An information processing device and image forming apparatus that includes a control device with a character orientation detector to adjust the orientation of preview images to a portrait orientation, ensuring characters are upright, and a rotation mechanism to switch between landscape and portrait orientations, along with a detection sensor to determine the display device's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device is rotated to landscape orientation to enlarge the preview image, then the display size is increased, but the characters become horizontal and difficult to read
Solution Approach 1:
The system dynamically adjusts the preview image orientation based on the detected display device orientation. When the display is rotated to landscape mode, the controller automatically rotates the preview image to maintain portrait orientation of characters, ensuring readability while utilizing the enlarged display area.
Solution Approach 2:
The controller changes the orientation parameter of the preview image according to the display device orientation detected by the detection sensor. This parameter adjustment ensures that characters remain in portrait orientation regardless of whether the display device is in landscape or portrait mode.
2Ease of operation
If the display device is rotated to portrait orientation to make characters upright, then character readability is improved, but the display size is reduced
Solution Approach 1:
The system dynamically adapts the preview image orientation to match the display device orientation. When the display is in portrait mode, the preview image is displayed in portrait orientation for readability. When rotated to landscape mode, the system automatically adjusts to maintain optimal character orientation while utilizing the larger display area.
Solution Approach 2:
The display device can operate in both landscape and portrait orientations, and the system provides universal support for both modes by automatically adjusting the preview image orientation based on detection sensor input, making the device versatile for different usage scenarios.
3Device complexity
If the preview image orientation is fixed regardless of display device rotation, then the system is simple to implement, but user experience deteriorates due to difficult-to-read characters
Solution Approach 1:
The system incorporates a detection sensor that provides feedback on the display device orientation to the controller. Based on this feedback, the controller automatically adjusts the preview image orientation, creating a closed-loop system that adapts to user actions and maintains optimal readability without requiring manual intervention.
Solution Approach 2:
The system performs self-adjustment by automatically detecting display orientation and rotating the preview image accordingly. This self-service mechanism eliminates the need for users to manually adjust orientation settings, simplifying the user experience while maintaining optimal character readability.

AI summary
An information processing device includes a display device and a control device. The control device includes a processor and functions, by the processor executing a control program, as: a controller that causes the display device to display a preview image of an output target image indicated by image data; and a character orientation detector that detects an orientation of characters in the output target image. The controller performs an orientation adjustment display for setting the orientation of the preview image to an orientation in which the orientation of characters detected by the character orientation detector becomes a portrait orientation in which the characters are upright, and displaying the preview image on the display device.
