Figures 5-1 to 5-4 show a comparison of video recording sizes, using a video dimension of
320x240 pixels and the HM compression method. The camera will generate many noise signals
in the nighttime because of low lighting, and will always create significantly large-size video
recordings.
Figure 5-1 shows the original picture at nighttime. Figure 5-2 illustrates that the noise reduction
process can reduce the video recording size, but still maintain the same video quality as Figure 5-
1. Figure 5-3 is the original picture in daytime, and Figure 5-4 shows that the size reduction ratio
is 24.8%.
