Fast FPGA-based frame grabber for digital progressive scan image sensors

The paper presents a custom designed frame grabber for a digital progressive scan image sensor. The system was designed using VHDL and then implemented within Spartan-6 FPGA. The whole project was successfully tested on Atlys development board with the MT9P031 image sensor attached. The architecture of the overall image acquisition system as well as its modules are described in details. Despite of its relatively simple structure, performed tests proved that the developed frame grabber achieves pixel stream speed up to 1.15 Gbps.
