12 description: |
13 The image renderer, or the distortion correction engine, is a drawing
14 processor with a simple instruction system capable of referencing video
15 capture data or data in an external memory as 2D texture data and performing
16 texture mapping and drawing with respect to any shape that is split into
17 triangular objects.
18
19 The image renderer light extended 4 (IMR-LX4) is found in R-Car Gen3 SoCs.
