VV5410 & VV6410

3.4.2 Sub-Sampled QCIF

In this mode the QCIF image is generated by sub-sampling the CIF image in groups of 4 to preserve the Bayer pattern with every

second group of pixels & lines skipped as illustrated in Figure 10. Although the former would not necessarily apply to a

monochrome sensor the same address sequence is preserved. VV5410 users should ignore the colour references in Figure 10.

Due to the crude nature of the sub-sampling, the resultant output image will be of inferior quality but contains full field of view and

is intended for use in gesture recognition applications or perhaps as a preview option before switching to pan tilt QCIF mode to

view the required scene region in more detail.
