[B0023] Arducam OV7670 0.3 Megapixel Camera Module for Arduino Boards

  • This Arduino camera comes with an F1.8/6 mm lens, it also supports AEC, AGC, AWB, ABF and ABLC, detailed specifications can be found below.
  • It can be connected to most Arduino boards, although we’d recommend using our SPI Modules for better performances.
  • Program requires the latest ArduCAM library and ArduCAM Shield_V2 shield and use Arduino IDE 1.6.8 compiler or above.

Description

Overview

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.

Demonstration

ArduCAM provides a full demonstration for OV7670 camera module on Arduino platform. Please download the ArduCAM_Shield_V2_Camera_Playback.ino from github.

It will turn the ArduCAM into a real digital camera with capture and playback functions.

1. Preview the live video on LCD Screen.
2. Capture and buffer the image to FIFO when shutter pressed quickly.
3. Store the image to Micro SD/TF card with BMP format.
4. Playback the capture photos one by one when shutter button hold on for 3 seconds.
