Caméra VGA pour arduino 640 x 480

Caméra VGA pour arduino 640 x 480


Description:


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.




Features:


● High sensitivity suitable for illumination applications


● Low voltage suitable for embedded applications


● Standard SCCB interface compatible with I2C interface


● RawRGB, RGB (GRB4: 2:2, RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2) output format


● Supports VGA, CIF, and from a variety of sizes CIF to 40x30


● VarioPixel sub-sampling mode


● Auto affect the control features include: automatic exposure control, automatic gain control, automatic white balance, automatic elimination light stripes, automatic black level calibration image quality controls including color saturation, hue, gamma, sharpness ANTI_BLOOM


● ISP has a compensation function to eliminate noise and dead pixels


● Support for image scaling


● compensation for loss of optical lens


● 50/60Hz automatic detection


● Saturation automatically adjust (UV adjustment)


● Automatically adjust edge enhancement


● Noise Reduction automatically adjust

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
Connections
Order Arduino ov7670
A5->SIOC
A4<->SIOD
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.
11-> (convert 5v to 3.3v) XCLK
