Solution Overview
Problem
Conventional image capturing devices, such as mobile phones and mature image capturing platforms, face challenges in efficiently capturing images of documents due to time-consuming object location and focusing, inadequate lighting conditions, and poor image quality resulting from underexposure or overexposure, especially when dealing with documents on various sizes and in different environments.
Innovation Solution
A portable image capturing electronic device with a main body, image capturing lens assembly, and light source assembly, where the light sources are positioned adjacent to the lens assembly to provide stable and adjustable illumination within an enclosed chamber, allowing for one-handed operation and efficient image capture with improved exposure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If mobile phones with photoflash or night-mode function are used to capture images in dim light, then illumination is improved, but image quality deteriorates due to overexposure or sharp light reflection
Solution Approach 1:
The patent applies local quality by positioning light sources at specific locations (above and below the accommodating chamber) to provide targeted illumination only where needed for document capture. This localized lighting approach ensures adequate illumination for reading and capturing text while avoiding excessive light intensity that would cause overexposure or reflection issues in the captured images.
Solution Approach 2:
The patent implements preliminary action by providing illumination before the image capturing moment. The light sources are positioned to illuminate the document in advance, allowing the user to read and position the document properly before triggering the camera capture, thus ensuring optimal lighting conditions without the need for high-intensity flash during capture.
2Productivity
If conventional image capturing devices are used, then image capture function is provided, but time is wasted in locating the object, focusing, and adjusting light intensity
Solution Approach 1:
The patent merges multiple functions into a single integrated device. The main body houses both the image capturing lens assembly and the light source assembly within the same accommodating chamber structure. This integration eliminates the need to separately locate and adjust external lighting devices, focusing mechanisms, and camera positioning, as all functions are unified in one handheld device with a unified control unit.
Solution Approach 2:
The patent implements multi-functionality by designing the main body to simultaneously perform illumination, image capture, and image processing functions. The device can adapt to different document sizes and lighting conditions through the unified control unit that manages both light sources and camera operation, making it a universal tool for various document capture scenarios without requiring multiple separate devices or manual adjustments.
3Adaptability or versatility
If documents on various sizes and in different environments are captured, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the lighting and capturing system adaptable to different conditions. The light sources can be independently controlled in intensity and timing, and the camera parameters can be adjusted by the unified control unit based on the captured scene. This dynamic adjustment capability allows the device to handle various document sizes and environmental conditions without requiring multiple fixed-configuration devices.
Solution Approach 2:
The patent implements parameter changes by allowing the unified control unit to adjust lighting intensity, exposure time, and other capture parameters based on the document size and environmental conditions. The system can modify these parameters dynamically to optimize image quality for different scenarios, from small documents in bright environments to large documents in dim lighting, without increasing physical device complexity.
