Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If Optical Image Stabilization (OIS) method is used to detect and correct user tremor, then image stability is improved, but device size and manufacturing cost increase due to required mechanical apparatus
Solution Approach 1:
The patent replaces the mechanical apparatus of OIS with a motion sensor (gyroscope) that detects user tremor through motion sensing. The control unit processes the motion sensor signal to determine tremor intensity and selects images taken during stable periods, eliminating the need for mechanical moving parts while achieving image stabilization.
Solution Approach 2:
The patent introduces a motion sensor as an intermediary between the user's tremor and the image capture system. The motion sensor detects tremor movements and provides signals to the control unit, which then uses this information to select appropriate images for storage, acting as a mediator that enables tremor correction without mechanical intervention.
2Volume of moving object
If digital image stabilization method is used to correct user tremor, then device size and cost are reduced, but processing time increases and pixel capacity is limited
Solution Approach 1:
The patent performs preliminary action by continuously capturing multiple temporary images during the shooting period and storing them in memory before final selection. The control unit determines tremor intensities for all captured images and identifies the best image for storage, eliminating the need for lengthy post-capture processing while ensuring the selected image has minimal tremor.
3Measurement precision
If multiple temporary images are captured and stored to select the best image, then image quality is improved, but memory usage and device complexity increase
Solution Approach 1:
The patent changes the parameter of image selection criteria by using motion sensor signals to objectively determine tremor intensity for each captured image. The control unit calculates tremor intensity based on motion sensor data and selects the image with the lowest tremor intensity, providing an automated, objective method for quality assessment that simplifies the selection process while improving image quality.
