Camera Integration Guide for Rivotek AI Platforms
Camera Interface Overview
Rivotek RV series processors support multiple camera interfaces for flexible system design. The primary interface is MIPI CSI-2, supporting high-resolution sensors with high frame rates.
MIPI CSI-2 Interface
Lane Configuration
RV processors support flexible MIPI lane configurations:
- RV300: 2-lane MIPI CSI-2 up to 1.5 Gbps/lane
- RV500: 4-lane MIPI CSI-2 up to 2.5 Gbps/lane
- RV1000/RV2000: 4-lane MIPI CSI-2 up to 4.5 Gbps/lane
Signal Routing
Proper PCB layout is critical for MIPI signal integrity:
- Route differential pairs with controlled 100Ω impedance
- Keep trace length matching within 2mm for all lanes
- Minimize via usage and layer transitions
- Keep away from noisy signals and power planes
ISP Configuration
The integrated ISP provides comprehensive image processing:
- Auto exposure and auto white balance
- Noise reduction and edge enhancement
- Lens shading correction
- HDR tone mapping
Tuning for Applications
Different applications require different ISP tuning:
- Surveillance: prioritize low-light performance
- Video conferencing: prioritize skin tone accuracy
- Industrial: prioritize edge sharpness
- Automotive: prioritize dynamic range

Frequently Asked Questions
1. What is the maximum cable length for MIPI CSI-2?
Maximum MIPI CSI-2 cable length depends on data rate and cable quality. At 1.5 Gbps/lane, up to 30cm is typically achievable with standard FPC cables. At 2.5 Gbps/lane, limit to 20cm. For longer distances, consider using MIPI repeaters or converting to LVDS. Always validate signal integrity with eye diagram measurements for your specific cable and routing.
2. How do I optimize image quality for low-light conditions?
Low-light optimization involves multiple factors: (1) Sensor selection - choose sensor with large pixels and good SNR; (2) Lens selection - use fast lens (f/2.0 or better); (3) ISP tuning - adjust noise reduction and sharpening for low-light; (4) Exposure settings - use longer exposure when motion allows; (5) Gain control - balance analog and digital gain. The Rivotek ISP provides advanced noise reduction specifically for low-light scenarios.
