Image Sensor MIPI Driver Development

Image Quality Labs provides end-to-end MIPI image sensor driver development, from sensor bring-up and power sequencing to V4L2/Linux integration and ISP tuning. We deliver production-ready drivers with multi-resolution support, HDR features, and full validation to ensure seamless performance and faster time-to-market.

1. Requirements & Planning

• Sensor and SoC platform analysis (datasheet review, reference code assessment)
• System architecture definition (lane configuration, bandwidth analysis, ISP compatibility)
• Device tree / board configuration planning

2. Driver Development

• Custom Linux V4L2 / Media Controller sub-device driver implementation
• I²C register initialization sequences (power-up, PLL, streaming modes)
• Multi-resolution and multi-frame-rate support (binning, skipping, HDR)
• Pixel format integration (RAW8/10/12, YUV422, RGB)

3. MIPI CSI-2 Configuration

• Lane mapping and data rate configuration
• D-PHY timing setup and validation
• Synchronization with SoC CSI receiver and ISP pipeline

4. Power & Control Management

• Regulator and power rail sequencing
• GPIO, reset, standby, and external clock integration
• Low-power and standby mode handling

5. ISP & System Integration

• Integration with SoC ISP blocks (auto-exposure, AWB, autofocus, HDR pipelines)
• Media controller graph linking (sensor → CSI receiver → ISP → output)
• Support for frame metadata (timing, embedded stats)

6. Testing & Debugging

• Bring-up validation with v4l2-ctl, GStreamer, and OpenCV tools
• MIPI signal integrity testing with analyzers/scopes
• Debugging I²C communications and streaming issues
• Regression testing across multiple resolutions and FPS

7. Optimization & Customization

• Frame rate tuning and latency reduction
• HDR / multi-exposure mode enablement
• Test pattern enablement for calibration
• External trigger, strobe/flash sync, and GPIO event integration

8. Documentation & Handoff

• Full driver documentation (integration notes, API usage, test procedures)
• Training/support for customer engineering teams
• Long-term maintenance and feature extension
