7.1.5 Filtering
A 3-tap or 5-tap FIR filter is used to reduce noise and aliasing artifacts produced by the CCD or
CMOS sensor, and the scaling process.
7.1.6 Captured Video Data Format
After cropped, down-scaled, and filtered in the video pre-processing (VPRE) block, the input video is
stored into the DRAM as captured video. Four different formats are supported for the captured video:
YUV4:2:2 packed, YUV4:2:0 packed, YUV4:2:2 planar, and YUV4:2:0 planar modes, which are
selected by bits 1-0 of the Video Capture Control register (CR26) as described in Table 7.1. YUV4:2:2
and YUV4:2:0 packed modes are used for original video transfer, while YUV4:2:2 and YUV4:2:0
planar modes are used for JPEG compression video transfer.
