ICX252AK
3. AF1 mode, AF2 mode
The AF modes increase the frame rate by cutting out a portion of the picture through high-speed elimination of
the top and bottom of the picture in high frame rate readout mode. AF1 allows 1/60s and 1/50s output, and
AF2 allows 1/120s and 1/100s output, so these modes are effective for raising the auto focus (AF) speed.
In addition, the cut-out can begin from an optional line by controlling the number of frame shift lines that sweep
the top of the picture. The relation between the number of frame shift lines, the output start position and
number of output lines is shown in the table below.

Output line is Up to 258 lines.
The i + 1 and i + 2 line signals may be disrupted by elimination of the picture top, so these lines should not
be used.
For example, if the picture top is eliminated with i = 100 in AF1 mode (NTSC), lines 103 to 208 in high frame
rate readout mode are output from 26H of the timing chart.
If the picture top is eliminated with i = 160 in AF1 mode (NTSC), lines 163 to 258 in high frame rate readout
mode are output from 26H of the timing chart.
