GINKGO  (8M, Lens Distortion Correction)

GINKGO is an LDC IP capable of up to 192° angle correction. 

GINKGO comes with factors that can adjust zoom and un-distortion strength. It can also perform viewpoint transformation through rotation, tilt, and pan functions.

RDMA (Read DMA) and WDMA (Write DMA) for the AXI interface are provided, as GINKGO uses external memory. 

GINKGO could be used by single IP and also be integrated with BTREE’s other ISP IPs.

* Tuning solution (such as image(Bayer) loader, ISP board and tool) can be purchased separately.
