Caméra VGA pour arduino 640 x 480


OV7670 image sensor, providing single-chip VGA camera and image processor for all functions

Through the SCCB bus control, outputFull frame, sub-sampling, taking a variety of windows, etc. affect the data resolution

Products VGA images up to 30 frames / sec. Users can fully control the image quality, data formats and transmission. All image processing functions including gamma curve process, white balance, saturation, hue and so on through the SCCB interface programming. OmmiVision image sensor applications unique sensor technology, by reducing or eliminating optical or electronic defects such as fixed pattern noise, prop tail, floating powder, etc., to improve image quality, get a clear and stable color image.

Exemple de code:

This is a version of code that sends data to the PC.
Unlike previous code this requires no external ram or fifo.
It just sends the data as it receives it.
The transfer rate is 1 mbps or 128kbytes per second
Order Arduino ov7670
Note what I have just described (above) are I2C connections you will need pullup resistors to 3.3v for both SIOC and SIOD.
You must not connect the resistors to 5v.
I have found that certain resistor values do not work such as 1K and 2.2K but found 4.7K and 10K to work.
