Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional digital cameras and video recorders are used without integrated pico projectors, then the device structure remains simple, but the ability to dynamically adjust lighting for optimal image capture is limited
Solution Approach 1:
The patent combines the pico projector and digital camera into a single integrated device, allowing the projector to serve dual purposes as both an image output device and a dynamic lighting source for camera capture, thereby enhancing adaptability without proportionally increasing complexity
Solution Approach 2:
The integrated pico projector serves multiple functions: it can project images for display and simultaneously function as a controllable lighting source for image capture, enabling the same hardware component to fulfill multiple roles based on operational needs
2Adaptability or versatility
If pico projectors are simply added as separate output devices, then image output capability is provided, but linkage and coordination between the projector and camera for optimized capture is absent
Solution Approach 1:
The system establishes bidirectional communication between the camera and projector through the processing unit, allowing real-time coordination where the camera captures scene information and the projector adjusts lighting accordingly, creating a feedback loop that optimizes image capture dynamically
Solution Approach 2:
The processing unit acts as an intermediary that receives data from both the camera and projector, processes the information, and coordinates their operations to achieve synchronized and optimized image capture and projection
3Illumination intensity
If uniform lighting is applied to the entire scene, then illumination is consistent, but specific areas requiring different lighting conditions cannot be optimized
Solution Approach 1:
The system divides the scene into multiple areas and applies different lighting conditions to each area based on captured image analysis, allowing optimization of illumination for specific regions of interest while maintaining overall scene coverage

AI summary
An image capturing device and a capturing method with light assistance are provided, wherein the image capturing device has a multi-directional lighting unit. In the method, at least two areas are defined continuously according to information provided by the image capturing device after the image capturing device enters a capture mode. Before a capture result is obtained, the multi-directional lighting unit is dynamically controlled to project different light beams to at least two latest areas.
