Driven by rising personal health consciousness and the proliferation of mobile healthcare technology, visual oral endoscopes are transitioning from professional dental clinics to diverse settings such as households, kindergartens, and beauty institutions. These devices enable visual oral health management through wireless WiFi connectivity, high-definition imaging, and waterproof designs. This article provides an in-depth analysis of the core technical requirements for endoscope camera modules based on current product characteristics and explores future development directions.
Current devices commonly adopt 1MP image sensors supporting 1080P HD transmission, representing a precise balance between cost, power consumption, and image quality:
Pixel Size and Light Sensitivity: The oral cavity's low-light environment requires larger pixel sizes (typically ≥1.75μm) to ensure sufficient light intake per pixel and reduce noise
Frame Rate Stability: Must maintain stable transmission above 30fps to prevent lag from affecting diagnostic experience
Color Accuracy: Accurate judgment of teeth and gum conditions depends on precise color reproduction, requiring superior white balance algorithms
The 6-LED configuration addresses unique lighting challenges in enclosed spaces:
Uniform Diffused Illumination: Ring layouts with 6-8 LEDs eliminate shadows for obstruction-free observation
Adjustable Brightness: Multi-level dimming prevents patient discomfort from excessive brightness
Anti-Fog Optical Design: Lenses require hydrophobic coatings to prevent condensation from breath from affecting imaging
Direct water rinsing, IP67 waterproof rating represents a fundamental requirement for oral medical devices:
Fully Sealed Structure: Camera modules must use medical-grade sealant to withstand repeated disinfection
Corrosion-Resistant Materials: Oral cavity contact requires biocompatibility certification (e.g., ISO 10993)
Mechanical Strength: Must pass drop tests (from 1m+ height) and bending tests to ensure daily durability
Built-in batteries enabling 3-hour standby impose stringent power consumption requirements:
Low-Power WiFi Module: 802.11n protocol with <200mW power consumption for transmission range within 30m
Efficient Encoding Chip: H.264/H.265 hardware encoding reduces SoC load and extends battery life
Smart Sleep Mechanism: Auto-sleep during inactivity with <1s wake-up response time
Expansion from oral examination to scalp, skin, and PCB inspection requires flexible focal lengths:
Fixed-Focus Design: Typically 5-15mm working distance with 3-10mm depth of field
Optimized Field of View: 60-90° FOV balances detailed observation with coverage area
Fast Switching Capability: Software-based toggling between macro and normal modes via algorithms
Higher Resolutions: 2MP and even 4MP sensors will gradually become mainstream, surpassing current 1080P limitations
Advanced Pixel Technologies: BSI (Backside Illuminated) and stacked structures will improve low-light performance by 30%+
AI Image Enhancement: Real-time HDR synthesis and multi-frame noise reduction will be integrated into ISP chips
Real-Time Lesion Detection: AI models accelerated by embedded NPUs can identify 20+ conditions including cavities, tartar, and oral ulcers
Smart Measurement Functions: Automatic calculation of cavity depth, gum recession distance, and other quantitative metrics
Cloud AI Diagnosis: 5G/WiFi 6E enables low-latency cloud analysis with accuracy comparable to professional dentists
WiFi 6E/7 Deployment: Tri-band concurrency with <50ms latency supporting multi-device simultaneous viewing
Proprietary Protocol Optimization: Custom low-power protocol stacks extending standby time to 8+ hours
UWB Precise Positioning: Integrated Ultra-Wideband technology enables 3D tracking of probe position
Smaller Module Size: Lens diameter reduction from 5mm to 3mm improves patient comfort
Flexible Circuit Application: FPC cables replacing traditional PCBs increase bend lifespan to 100,000+ cycles
Antimicrobial Surface Treatment: Nano-silver ion coatings inhibit 99.9% of bacterial growth
Home Edition: Focused on ease-of-use with one-button operation and built-in health record management in the app
Professional Edition: DICOM-compliant, integrable with hospital PACS systems
Industrial Edition: Enhanced anti-static design for precision PCB inspection
Beauty Edition: Integrated sensors for skin moisture and oil detection
As devices enter households, end-to-end encryption will become standard, complying with HIPAA, GDPR, and other medical data regulations. Camera modules will integrate hardware-level encryption engines to ensure video streams cannot be intercepted.
Camera modules for visual oral endoscopes are rapidly evolving toward higher definition, intelligence, lower power consumption, and specialization. The current 1MP/1080P configuration indicates the industry is transitioning from "functional" to "user-friendly." In the next 3-5 years, with the miniaturization of AI chips and WiFi 7 adoption, oral endoscopes will evolve into intelligent terminals for personal health management, and camera modules will upgrade from single imaging components to **integrated sensing-computing-communication system-level solutions.
Manufacturers must continuously innovate across sensor selection, optical design, power optimization, and AI integration while meeting medical-grade safety certifications to secure a leading position in the trillion-dollar personal health market.
