Terasic auto-focus IP through its own I2C master controller. Users must make sure
there is only one I2C master used a time.
◼ KEY IP Descriptions
In this demonstration, the default camera settings are:
⚫ Terasic Camera IP implements RAW to RGB and avalon-ST streaming
package conversion.
⚫ Terasic AutoFocus IP implements Simplified AutoFocus function.
⚫ Scaler IP implements Scaling function. Combining with software
configuration, it can scale two 640x480 images to proper size to fit the
bandwidth limitations (100MHz x 16bit) of the SDRAM.
⚫ Frame Buffer IP can read and write image stream into the SDRAM
⚫ Mixer IP Camera will blend two image data into one picture (resolution is
800x600).
⚫ Clock Video Output block will output the image data (resolution is 800x600)
from the Mixer IP to the VGA monitor.
◼ The default camera settings
In this demonstration, the default camera settings are:
⚫ Resolution: 600x480
⚫ Frame Rate: 50 fps
⚫ Pixel Data: RAW10
⚫ Bin Mode: 1, 2, 4 (achieved ZOOM-IN/ ZOOM-OUT function)
Camera1 default settings:
⚫ Resolution: 600x480
⚫ Frame Rate: 50 fps
⚫ Pixel Data: RAW10
⚫ Bin Mode: 1, 2, 4 (achieved ZOOM-IN/ ZOOM-OUT function)
Users can change the settings base on their requirements.
◼ Synchronize Two D8M Data Streaming
There is a simple way to synchronize multiple D8M’s “Frame Start” signals. See Table
5-2 follow the “Hardware standby with PWDNB” mode. After configuring all of the
D8M’s registers, just pulling all of the D8M’s “PWDNB” signal low for a while at the
same time. In this way, the register setting will not be clear and it will synchronize all
