Designing a wearable night vision camera is a complex task, particularly when the device must be lightweight, compact, and power-efficient while meeting stringent military standards. The camera needed to integrate two distinct imaging sources — an infrared camera and a low-light camera — to provide superior night vision in challenging environments. The integration of these sources presented a significant challenge. The camera had to process and synchronize high-speed signals from both cameras despite their differing resolutions. This required an advanced FPGA (Field Programmable Gate Array) design capable of managing high-speed parallel processing and video synchronization within the compact confines of a wearable device.
