Características

Description:

OV7670 image sensor, small volume, low operating voltage, providing all functions of a single chip of VGA camera and image processor. Through SCCB bus control, the sensor can output the whole frame, sampling, and various resolution 8 bits of data. The product VGA image can reach up to a maximum of 30 frames per second. Users can completely control the image quality, data format and transmission mode. All the process of image processing functions can be through the SCCB programming interface, including gamma curve, white balance, saturation and chroma .

 

 Features:

  • Optical size 1/6 inch
  • Resolution 640×480 VGA
  • Onboard regulator, only single 3.3V supply needed
  • Standard 0.1inch (2.54mm) pin pitch header connector
  • Mounted with high quality F1.8 / 6mm lens
  • Output support for Raw RGB, RGB (GRB 4:2:2, RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2) formats
  • High sensitivity for low-light operation
  • Low operating voltage for embedded portable apps
  • Standard SCCB interface compatible with I2C interface
  • Supports image sizes: VGA, CIF, and any size scaling down from CIF to 40×30
  • VarioPixel® method for sub-sampling
  • Automatic image control functions including: Automatic
  • Exposure Control (AEC), Automatic Gain Control (AGC), Automatic White Balance (AWB), Automatic
  • Band Filter (ABF), and Automatic Black-Level Calibration (ABLC)
  • Image quality controls including color saturation, hue, gamma, sharpness (edge enhancement), and anti-blooming

The following schematic diagram show a basic camera based system. The camera module is powered from a single +3.3V power supply. An external oscillator provide the clock source for camera module XCLK pin. With proper configuration to the camera internal registers via I2C bus, then the camera supply pixel clock (PCLK) and camera data (Data[9:0]) back to the host with synchronize signal like HREF and VSYNC.

The host may have integrate camera interface like STM32F2 or STM32F4 series MCUs, or ARM9/11 which has dedicate camera port, and DPS like TI TMS320DM series, as well as FPGAs that user can design special logic for camera application. The typical connection between these system and camera module would show like following diagram.

For the host that doesn’t have a dedicate camera interface, additional hardware is needed. User need to buffer a entire frame before read them out with low speed MCUs. For example ArduCAM shield is a additional hardware that can be connected to Arduino UNO/Mega board, user can take a photo or something like that easily. The following diagram show the system without dedicate camera interface.
