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