Figure 9-159 shows the low-pass filter (LPF) block diagram.
An optional horizontal low-pass anti-aliasing filter (LPF) can be applied (the ISIF_MODESET[14] HLPF bit) after reframing. The LPF consists of a simple 3-tap (1/4, 1/2, and 1/4) filter. Two pixels on the left and two pixels on the right of each line are cropped if the filter is enabled. Use of the LPF is intended for bandwidth reduction if culling is enabled.
For YUV data, the LPF must be disabled (ISIF_MODESET[14] HLPF = 0x0).
