9.1.4 Sub-sampling Digital Zoom
TM/TMC-4200CL has four sub-sampling digital zoom modes:1x, 2x, 3x, and 4x. Effective pixels in
these modes are 512(H) x 1024(V). In 1x mode, the output video uses all the pixels in the center 512(H)
x 512(V) of the CCD sensor. In 2x mode the output video is every other pixel in the horizontal row, and
every other line in the vertical rows at the center 1024(H) x 1024(V) of the CCD sensor. In the 3x mode
the output video is every other two pixels in the horizontal row and every other two lines in the vertical
row of the center 1536(H) x 1536(V) of the CCD sensor. In 4x mode output video is every other three
pixels in the horizontal row, and every-other three lines in the vertical rows of the full scan area, which
is 2048(H) x 2048(V).
