4 Raspberry Pi PiSP Back End Memory-to-Memory ISP (pisp-be)
10 The PiSP Back End is a memory-to-memory Image Signal Processor (ISP) which reads
11 image data from DRAM memory and performs image processing as specified by the
16 Image Signal Processor (PiSP) Specification document`_
18 The PiSP Back End ISP processes images in tiles. The handling of image
19 tessellation and the computation of low-level configuration parameters is
23 The full image processing pipeline, which involves capturing RAW Bayer data from
24 an image sensor through a MIPI CSI-2 compatible capture interface, storing them
