Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices lack an efficient method for conveniently adjusting crop frames, which is essential for segmenting specific portions of images, as current methods are not user-friendly or intuitive for resizing and zooming operations.
Innovation Solution
An image processing device and method that includes a display component, touch sensor, and processing component to display an image and crop frame, allowing users to resize and zoom the crop frame by detecting touches within a virtual frame, shifting adjacent sides based on touch movements, and calculating displacements to adjust the frame's position and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional crop frame adjustment methods are used, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent replaces traditional mechanical crop frame adjustment mechanisms with a touch-sensitive interface. Users can adjust the crop frame by touching and dragging on a virtual representation of the frame displayed on a screen, eliminating the need for physical knobs, sliders, or buttons. This substitution of mechanical controls with a graphical user interface directly improves ease of operation while reducing mechanical device complexity.
Solution Approach 2:
The patent creates a virtual copy of the crop frame displayed on a screen that users can manipulate. Instead of directly manipulating the physical crop frame, users interact with a two-dimensional graphical representation that mirrors the crop frame's position and dimensions. This copying approach allows for intuitive touch-based adjustment without requiring complex mechanical transmission mechanisms.
2Manufacturing precision
If precise crop frame adjustment is enabled, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements real-time visual feedback by displaying the crop frame's position and dimensions on a screen as users touch and drag. The virtual representation updates continuously to reflect the current crop frame state, providing users with immediate visual confirmation of their adjustments. This feedback mechanism enables precise positioning while maintaining ease of operation, as users can see exactly where the crop frame is positioned without requiring complex precision mechanisms.
Solution Approach 2:
The patent replaces precision mechanical adjustment mechanisms with software-based control through touch input. The touch-sensitive screen and processing system can detect and respond to user gestures with high precision, eliminating the need for mechanical precision components while achieving accurate crop frame positioning through digital signal processing and coordinate transformation.
3Ease of operation
If touch-based resizing is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes a touch-sensitive display screen that serves multiple functions: displaying the image, showing the crop frame, detecting user touches, and providing visual feedback. This multi-functional device eliminates the need for separate touch sensors, display components, and control mechanisms, thereby improving ease of operation through intuitive touch interaction while actually reducing overall device complexity through functional integration.
Solution Approach 2:
The touch-sensitive display screen automatically detects user touches and processes the resize operation without requiring additional control circuits or intermediary components. The screen itself serves as both the input device and the output device, processing touch coordinates and updating the display in real-time. This self-service capability improves intuitiveness while minimizing added complexity, as the same component handles both display and input functions.
