VGA camera module OV7670 has a maximum resolution of 640x480 pixels (0.3 megapixels) and low supply voltage. Equipped with a single-chip CMOS image sensor has a wide range of aspect ratios. Is controlled by the bus Serial Camera Control Bus (SCCB), which is analogous to the bus I2C, IIC.

VGA camera module OV7670 is used to capture, primary processing and image transmission to the controller, the display, the other image processing apparatus, etc.

VGA camera module OV7670 can be controlled by Arduino controller, another microprocessor control unit, as well as from a computer using special software to control serial ports (Serial port).

In order to use VGA camera module OV7670 , you need to connect the power - to connect to Arduino controller (or other microprocessor control unit), the display, the other image processing apparatus, etc. You can start working. The lens is screwed on the thread and you can use the scroll thread to change the distance from the lens to the single-chip CMOS sensor.

VGA camera module OV7670 can give his image at up to 30 frames per second. Video Interface uses the clock for Personnel VSYNC, HREF in lines and pixels PCLK. Pixel data representing coded information about its color, issued on 8-bit parallel interface D7 - D0 in cycles PCLK. In the case of encoding RGB color pixel data issued in two bytes. It is also possible YCbCr encoding.

To modulyaVGA camera OV7670 There are a lot of settings. For example, it is possible to use such a frame format:

  • VGA (640 x 480);
  • QVGA (320 x 240);
  • CIF (352 x 240);
  • QCIF (176 × 144);
  • manual scaling.

VGA camera module OV7670 has one 18-pin interface for input, output signal and power:

  • VDD - food;
  • GND - general;
  • SDIOC - (input) clock serial SCCB camera control;
  • SDIOD - (input / output) data signal (data) serial SCCB camera control;
  • VSYNC - (output) pulse frame synchronization;
  • HREF - (output) horizontal sync pulse;
  • PCLK - (output) clock issue byte parallel port D7 - D0;
  • XCLK - (input) the main clock for OV7670;
  • D7 - D0 - 8-bit parallel video output;
  • RESET (Reset) - output hardware reset the camera;
  • PWDN - output hardware on / off camera.
