Pan/Tilt

Pan/Tilt is a function used to move a camera up and

down or left and right. However this camera supports a

video mode much smaller than the CCD's effective

pixels by cutting out images from the whole screen. You

can specify the portion to be cut out using Pan/Tilt

commands.

The variable range differs according to the selected

video mode.

When a video mode is changed, the pan/tilt values are

set to the default setting.

Brightness

This feature controls the black level of a video image.

Sharpness (Black and

white models only)

This feature controls the image quality.

A smaller value makes the image softer, and a larger

value makes it sharper.

The Sharpness feature cannot be used together with the

3 × 3 filter.

Saturation (Color

models only)

This feature controls the color density.

White Balance (Color

models only)

This feature controls the white balance by setting the R

and B levels relative to the G level.

The camera also supports the Auto white balance by

which the camera automatically adjusts the white

balance.

Hue (Color models only)

When the white balance cannot be obtained with the R

and B level adjustment, you can change the G level by

hue adjustment. Normally use the default hue setting.

Trigger Delay

Issue of a trigger signal can be delayed from the external

trigger inside the camera.

This delay adjustment is useful to get an appropriate

shooting timing when the position of the subject is not

good at a regular trigger timing.

GPIO

A general-purpose I/O port with a 2-bit output and 2-bit

input is assigned in the 12-pin connector.

This port is used for reading information of external

switches and sensors from the camera and controlling

external devices.

The output terminal is of the open-collector type and

should be pulled outside of the camera (5 to 24 V).

Note on input

Connect to ISO (GND) using an input device with a

minimum signal width of 0.5 msec and an input current

of 0.5 mA or more.

Note on output

Use the following conditions:

Recommended pull-up resistor: 4.7 kΩ

Recommended pull-up voltage: 5 V

Minimum signal width: 0.5 msec

The camera is equipped with a protective resistor of 220

Ω. If the above conditions prove difficult in use, check

the output voltage and determine the external pull-up

resistor.
