Moduł kamery OV7670 + AL422B(FIFO) (V2.0)

Description

1、380KB high-capacity FIFO AL422B, very suitable for slow MCU to acquisit image data directly through the I/O

2、24MHZ active crystal oscillator

3、OV7670 2.8 V voltage stabilization LDO

4、Single work power 3.3 V (+ / -0.1 V), working temperature from 0 degrees - 50 degrees

5、The camera is all the glass lenses, lens (including seat) is magnesium alloy material, focal length of the lens is 3.6 millimeters 650nm bands

6、 PCB is black FR - 4 ,quality heavy gold plate, effectively prevent the PCB from light leak problems (if it is not black, this module will have light leak problem and the images will have a shadow)

7、Module size is 3 * 3 centimeters (+ / - 0.5 mm)

8、 Module pin is standard interface 2X10 2.54 mm, and convenient for cable to connect directly with microcontroller I/O for collecting images.

Main Function

1、Support low illumination applications for high sensitivity

2、Support SCCB interface,and compatible with the I2C interface

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

4、Support VAG、CIF and support all kinds of size from CIF to 40x30 size

5、Support VarioPixel sampling way

6、Support Automatic influencing control functions include: automatic exposure control, automatic gain control, automatic white balance, automatic eliminate light stripe, automatic black level calibration. Image quality control including the color saturation, hue, gamma, ANTI_BLOOM sharpness

7、The ISP support eliminating noise and compensation bad point function

8、Support image scaling

9、Support compensation losing light

10、50/60Hz automatic detection

11、Support adjusting saturation automatically(UV adjust)

12、Support adjusting Edge enhanced function automatically

13、Support adjusting noise reduction function automatically
