MAPLE  (5M, Lens Distortion Correction)

MAPLE supports wide-angle correction. MAPLE comes with factors that can adjust zoom and un-distortion strength.

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

MAPLE 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.
