VOUT
1. Progressive scan mode
In this mode, all pixels signals are output in non-interlace format in 1/15s.
The vertical resolution is approximately 800 TV-lines and all pixels signals within the same exposure period
are read out simultaneously, making this mode suitable for high resolution image capturing.
2. High frame rate readout mode
All effective areas are scanned in approximately 1/30s by reading out two out of four lines (3rd and 4th
lines, 7th and 8th lines). The vertical resolution is approximately 400 TV-lines.
This readout mode emphasizes processing speed over vertical resolution.
3. High frame rate readout two pixels addition mode
All effective areas are scanned in approximately 1/30s by reading out two out of four lines (3rd and 4th
lines, 7th and 8th lines), and by reading out two out of the remaining four lines (1st and 2nd lines, 5th and
6th lines) after shifting the vertical register by 2 bits, and adding them in the vertical register.
