| Metric | Measured Value | Specification | Comment | |--------|----------------|---------------|---------| | Effective Pixel Size | 1.12 µm | – | Small pixel size yields high resolution but can increase noise at low light – mitigated by backside illumination. | | Quantum Efficiency (peak) | 78 % @ 550 nm | ≥ 70 % | Excellent photon conversion efficiency. | | Signal‑to‑Noise Ratio (SNR) | 45 dB (ISO 200, 1 ms) | ≥ 42 dB | Meets target for most daylight scenarios. | | Dynamic Range | 75 dB (HDR mode) | ≥ 70 dB | Dual‑exposure HDR provides extended range for high‑contrast scenes. | | Distortion | < 0.3 % barrel | ≤ 0.5 % | Within tolerances for machine‑vision pipelines. | | MTF (Modulation Transfer Function) | 30 % at 2 lp/px | ≥ 28 % | Good edge‑detail preservation. |
| Feature | SP‑91 | Competitor A (MicroCam‑X) | Competitor B (Visio‑Lite) | Competitor C (NanoEye‑Pro) | |---------|-------|---------------------------|---------------------------|----------------------------| | Resolution | 12 MP | 8 MP | 13 MP | 12 MP | | Form Factor | 9 × 9 × 3.2 mm | 10 × 10 × 4 mm | 8 × 8 × 2.8 mm | 9 × 9 × 3.5 mm | | Power (Full‑Video) | 150 mW | 210 mW | 180 mW | 140 mW | | HDR | 2‑frame (75 dB) | Single‑exposure | 2‑frame (68 dB) | 2‑frame (70 dB) | | On‑Chip AI | Yes (8‑bit Conv) | No | Yes (16‑bit Conv) | No | | MIPI Lanes | 4 | 2 | 4 | 2 | | Cost (per unit) | $12.80 | $13.50 | $14.20 | $12.10 | | Availability | Q2‑2026 (12 M units) | Q4‑2025 (6 M units) | Q1‑2026 (8 M units) | Q3‑2026 (10 M units) |
Take‑away: SP‑91 offers the best blend of power efficiency, HDR capability, and built‑in AI acceleration while keeping the price competitive. The only marginal advantage of Competitor C is a slightly lower unit cost, but it lacks on‑chip AI and has higher standby power.
| Risk | Likelihood | Impact | Mitigation | |------|------------|--------|------------| | Supply‑Chain Bottleneck (QFN‑48 lead time) | Medium | High (delays in production) | Secure dual‑source for QFN package; maintain safety stock of 5 M units. | | Firmware Compatibility (MIPI‑CSI driver updates) | Low | Medium | Contribute upstream patches to Linux kernel; maintain a version‑controlled driver repo. | | Thermal Accumulation in Enclosed Enclosures | Low | Medium | Add thermal vias to PCB; use low‑profile heat‑spreaders when necessary. | | Regulatory Compliance (RoHS, REACH) | Very Low | Low | Confirm all components are certified; retain full documentation for audits. | | AI Model Obsolescence | Medium | Low | Provide OTA update framework for AI kernels; modular SDK allows third‑party model integration. |
| Domain | Fit‑Score (1‑5) | Reasoning | |--------|----------------|-----------| | Wearable Vision (AR glasses, smart helmets) | 5 | Tiny footprint, low standby power, on‑chip AI for gesture/eye‑tracking. | | Industrial IoT (Predictive Maintenance cameras) | 4 | Robust temperature range, HDR for variable lighting, MIPI‑CSI integration with edge compute. | | Autonomous Drones / Swarm Robotics | 4 | Light weight (< 1 g), low power, 4‑K video for mapping; AI for obstacle detection. | | Smart Home Appliances (Fridge inventory, robot vacuums) | 3 | Adequate resolution, but cost may be higher than needed for basic detection. | | Medical Wearables (Dermatology patch, vital‑sign monitoring) | 3 | Good image quality, but regulatory clearance still pending (ISO‑13485). | | Consumer Electronics (Mini‑cameras for smartphones) | 2 | Market already saturated with larger sensors; size advantage not decisive. |
