3.2 Lens Distortion Correction (LDC) Block

The LDC is a dedicated hardware accelerator capable of flexible perspective transformations. These transformations are necessary because the final mirror view displayed on the monitor is constructed taking the following into account:

  • Input fish-eye lens distortion correction
  • Driver viewing perspective adjustment
  • Emulation of the aspherical side-view mirror effect digitally

In Figure 3-2, aspherical mirror emulation compresses the right side of the view horizontally so that a wider view can fit into a smaller CMS monitor.
