- Output Formats (8-bit): YUV/YCbCr (4:2:2), RGB (RGB565/555/444, GRB4:2:2), and Raw RGB.
- Image Processing: Built-in ISP for auto-exposure (AEC), auto-white balance (AWB), noise reduction, gamma correction, saturation, sharpness, and lens shade compensation.
- Key Specs:
- Pixel Size: $3.6\,\mu\text{m} \times 3.6\,\mu\text{m}$ (1/6" optical size)
- Sensitivity: 1.3V/(Lux-sec) with a 46 dB SNR
- Operating Voltage: 2.5V – 3.0V (low power consumption: 60mW active, $<20\,\mu\text{A}$ sleep)
- Lens FOV: 25° field of view
