OV7670 Camera Module

OV7670 Camera Module

The OV7670 is a compact and cost-effective CMOS camera module designed for embedded vision applications. It is ideal for use with Arduino, FPGA, and other microcontroller platforms. The module provides real-time VGA (640x480) video capture and supports various output formats including YUV, RGB, and raw data.

Key Features:

• High sensitivity for low-light operation
• Low operating voltage for portable embedded systems
• Standard SCCB interface (compatible with I2C)
• Supports VGA, CIF, and lower resolutions
• Output formats: RGB565/555, GRB 4:2:2, YUV 4:2:2, YCbCr 4:2:2, and raw RGB
• VarioPixel® sub-sampling for lower resolutions
• Built-in automatic image control:
  • Auto Exposure Control (AEC)
  • Auto Gain Control (AGC)
  • Auto White Balance (AWB)
  • Auto Band Filter (ABF)
  • Auto Black-Level Calibration (ABLC)
• Image enhancements: color saturation, hue, gamma, sharpness, anti-blooming
• Noise reduction and defect correction
• Supports LED flash, strobe, and scaling
• Flicker detection (50/60 Hz), lens shading correction
• Auto-adjust for saturation, edge enhancement, and de-noise levels
