ξ VARIABLE : The shutter speed is VARIABLE value under a line.
a)8 to 1/30 (1/25 : PAL) :
4 to 1/30 (1/25 : PAL) :
The camera delivers intermittent video signal output. So, to view continuous images, it is required to use the video memory. A clear image can be attained even if the subject is illuminated with a faint light source. As the store time increases, the degree of
Note : With an increase in store time, the degree of characteristic pattern noise, white scratch, etc. of the CCD image sensor will become higher.
b)1/60.38 (1/50.31: PAL) to 1/100,000 : Lock scan mode
When an image of a subject display screen having a different scan frequency is taken, a bright or dark horizontal bar appears to roll up or down the screen. The shutter speed can be adjusted to where the horizontal bars are minimized in the display.
Note : If the display screen scanning frequency is less than 60Hz (50Hz PAL), the rolling horizontal bars cannot be stopped. Not settable in the Auto CAM mode.
ξ AES | : Auto electronic shutter operates in the Limit range setting. |
| Optimum image level is obtained under strong light conditions. |
| Effectively used for special optical systems such as microscope or |
| fixed iris lens which do not have automatic light adjustment |
| functions. Limit settings can be selected from 1/500 to 1/100000 |
| second |
Note: AES cannot be used with Lens Type Video. To use AES with a manual iris lens, set the Lens Type to DC and Iris Mode to Manual. If the iris opening is relatively wide in comparison to the DC voltage (manual
Note: In the Auto CAM mode and the Lens Type is set to DC, the shutter is set to AES. If Lens Type is set to Video, default is to off.
ξ EXT TRIGGER : External trigger refer to a function for picking up rapidly moving objects by applying a trigger pulse input.
It is possible to pick up an image with various timing, by the mode that was set in EXT TRIGGER under 1 line.
3) EXT TRIGGER : external trigger mode
For details of MODE1, MODE2, please refer to Page 27.
4) CCD MODE : CCD store mode
ξ FLD : The field integration mode operation is performed (for ordinary purpose of application).
ξ FRM : Frame integration mode; although vertical resolution is improved, image lag is slightly increased. Suggested for still images. At AES Shutter mode, camera sensitivity is reduced by about 6 dB.
