Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatus with image display functions, such as smartphones and digital cameras, experience unclear images due to shaking, as the display panel's movement causes persistence of vision issues for human eyes.
Innovation Solution
An electronic apparatus with image stabilization, comprising a display device, sensor, and processor, detects movement parameters and calculates compensation data to shift the reference image point on the display panel, ensuring clear image display by adjusting the image data and display parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the display panel moves with the electronic apparatus during shaking, then the display follows the device movement naturally, but the image becomes unclear due to persistence of vision
Solution Approach 1:
The processor calculates compensation data in advance based on movement parameters detected by the sensor, before the actual display occurs. This preliminary calculation allows the display device to pre-position image points to counteract upcoming shaking movements, maintaining image clarity without requiring complex real-time adjustments during shaking
Solution Approach 2:
Compensation data serves as an intermediary between the movement parameters and the display output. The processor generates this intermediate compensation information that translates device movement into corresponding image point adjustments, simplifying the overall control mechanism while achieving stable image display
2Stability of the object's composition
If the display panel remains stationary while the apparatus shakes, then image clarity is maintained, but the display does not follow the natural device movement
Solution Approach 1:
Instead of mechanically stabilizing the display panel or using physical stabilization mechanisms, the patent substitutes a computational approach where the processor calculates and applies compensation data to adjust image point positions. This replaces complex mechanical stabilization systems with software-based image processing
Solution Approach 2:
The system dynamically changes display parameters by adjusting the positions of image points on the display panel based on compensation data. This parameter adjustment allows the image to be repositioned virtually without physically moving the display panel, achieving stability through digital rather than mechanical means
3Reliability
If compensation data is calculated and applied to shift image points, then image clarity is maintained during shaking, but the processing time and computational load increase
Solution Approach 1:
The compensation data is calculated in advance based on detected movement parameters, allowing the system to prepare correction information before the shaking fully impacts image display. This preliminary calculation reduces the need for complex real-time processing during critical moments
Solution Approach 2:
The system uses feedback from movement parameters detected by the sensor to continuously adjust and optimize compensation data. This feedback mechanism allows the processor to learn from actual shaking patterns and refine compensation calculations, improving efficiency and reducing processing time over time

AI summary
An electronic apparatus is provided. The electronic apparatus includes a display device, a sensor, and a processor. The display device receives an image data. The display device includes a display panel and displays an image related to the image data on the display panel. A reference image point of the image is displayed on a first location on the display panel. The sensor detects a movement status of the electronic apparatus when the electronic apparatus shakes to generate at least one movement parameter. The processor calculates compensation data according to the at least one movement parameter and size information of the display panel. When the display device receives the compensation data, the display device displays the image by shifting the reference image point of the image from the first location to a second location on the display panel to display according to the compensation data.
