|
|
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.
