8 Mega Pixel Digital Camera Package with GPIO interface

Terasic D8M-GPIO is an 8-megapixel camera kit with a 2x20 pin GPIO connector interface. It includes a MIPI camera module and a MIPI decoder.

The MIPI camera module captures images and sends them out in a MIPI video signal package. This packet is converted into a 10-bit parallel Bayer pattern through a MIPI decoder. The data is transmitted through a 2x20 pin GPIO connector. The MIPI camera module has a built-in Voice Coil Motor (VCM) to control its focal length. Users can adjust the focus via the I2C interface.  

The 2x20 pin GPIO connector is the standard expansion interface widely used on Altera DE series development kits. Any main boards with a GPIO connector can interface with D8M-GPIO.

Terasic D8M-GPIO kit also includes camera capture and display reference design. It comes in two versions. One is  only  RTL code and the other one uses components such as Altera VIP in Qsys. It enables users to rapidly be familiar with the operation of the camera module and develop custom applications based on these examples as a reference.

Block Diagram

The functional block diagram of D8M-GPIO is shown above. MIPI Camera Module sends the video captured to the MIPI Decoder via MIPI link. MIPI Decoder converts MIPI Video Data to parallel data and output to the main board through a 2x20 pin GPIO connector. The parameters of the MIPI Camera Module and MIPI Decoder can be configured by FPGA via I2C interface. For instance, the number of output pixels from the MIPI Camera Modules, RGB gain, position of focus, PLL of MIPI Decoder, and parameters of Video MIPI Decoder etc.
