| 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. |
