For example, with the normal setting (about 1 second), if the headlights of a car are caught by the camera, the camera automatically adjusts the exposure so that it can shoot a high-intensity subject (in this case, the headlights). As a result, images around the headlights, that is, the rest of the subject, except the headlights, becomes relatively dark, and poorly distinguished. However, using the slow AE function means the AE response speed will be slower, and response time will be longer. As a result, even if the camera catches a high-intensity subject (e.g., the headlights) for a moment, you can still easily distinguish the portions of the image surrounding the headlights.

Slow AE (Automatic Exposure)
The slow AE Response (automatic exposure) function
allows you to reduce the exposure response speed.
Usually the camera is set up so that the optimum
exposure can be obtained automatically within about 1
second. However, using the slow AE response function
allows you to lengthen the automatic exposure
response speed from the factory setup speed (01 (hex)
up to 32 times (20 (hex)).
For example, with the normal setting (about 1 second),
if the headlights of a car are caught by the camera, the
camera automatically adjusts the exposure so that it
can shoot a high-intensity subject (in this case, the
headlights). As a result, images around the headlights,
that is, the rest of the subject, except the headlights,
becomes relatively dark, and poorly distinguished.
However, using the slow AE function means the AE
response speed will be slower, and response time will
be longer. As a result, even if the camera catches a
high-intensity subject (e.g., the headlights) for a
moment, you can still easily distinguish the portions of
the image surrounding the headlights.
High Resolution Mode (Default)
A newly developed DSP function enables the filtering
of signals. This allows the camera to provide images
with a high resolution (530 TV lines).
When this function is set to OFF, the camera outputs
images which are equivalent to 470 TV lines.
Aperture Control
Aperture control is a function which adjusts the
enhancement of the edges of objects in the picture.
There are 16 levels of adjustment, starting from “no
enhancement.” When shooting text, this control may
help by making them sharper.
Back Light Compensation
When the background of the subject is too bright, or
when the subject is too dark due to shooting in the AE
mode, back light compensation will make the subject
appear clearer.
Slow shutter – Auto/Manual
When set to “Auto,” ensures that the slow shutter is set
automatically when the brightness drops. Effective
only when the AE mode is set to “Full Auto.”
Set to “Slow Shutter Manual” at shipment.
Camera ID
The ID can be set up to 65,536 (0000 to FFFF). As this
will be memorized in the nonvolatile memory inside,
data will be saved regardless of whether it has been
backed up.

It consists of the following functions.

E-FLIP
This function turns the video output from the camera

continuously.
Because communication inside the camera is based on V
