Specifications


Step 1: General Description

This camera module can perform image processing such as AWB (auto white balance), AE (automatic exposure) and AGC (automatic gain control), for the video signal coming from CMOS sensor. What’s more, in fusion of other advanced technology such as image enhancement processing under low illumination, and image noise intelligent forecast and suppress, this module would output high quality digital video signals by standard CCIR656 interface. OV7670 built-in JPEG decoder supported reatime encoding for collected image, and external controller can easily read the M – JPEG video streams, achieving the camera design of double stream. OV7670 supported motion detection and OSD display function of screen characters and pattern overlay, capable of self-defining detection area and sensitivity.

  1. Firstly download the two files of Camera_OV0706_lib and Camera_OV0706_TEST from the Camera Module Code written by ElecFreaks and then unzip it.
  2. Put the unzipped file of Camera_OV0706_lib into the Arduino IDE folder of Libraries.

  3. Open unzipped file of Camera_OV0706_TEST, and the program the code into UNO. The detailed steps are demonstrated in the pictures.

  4. Click Tools,and then choose the board of Arduino UNO.

  5. Click Tools / Serial Port,and then choose the corresponding COM number.

  6. And then click the button of programming like below in red rectangle, program the code into the UNO board until done uploading appears.

  7. Finally open the monitoring serial port as below in red rectangle.

  8. When the serial port display the data like demonstrated below, you can press the digital keys to take a photo.

  9. If photo was taken successfully, the serial port would be displayed.

Until now, the module testing has been completed. Thanks for reading.
