The OMAP Resizer module enables up scaling and down scaling. It resizes
YUV422 image and stores output image in the RAM. The following figure shows
the block diagram for Resizer module.
Figure 7.1. OMAP Resizer HW Block Diagram
The Resizer module performs digital zoom either up sampling or down sampling
on image/video data within a range of 0.25x to 4x resizing. The input source
can be sent to either the preview engine/CCDC or memory, and the output is
sent to memory.
The Resizer module performs horizontal resizing, then vertical resizing,
independently. Between them, there is an optional edge-enhancement feature.
This process is shown in the above Figure.
