Basic Functions

Basic Functions

Zoom

The camera employs an 18× optical zoom lens combined with a digital zoom function allowing you to zoom up to 216×.

Lens specifications: Optical 18×, f = 4.1 to 73.8 mm (F1.4 to F3.0)

The horizontal angle of view is approximately 48 degrees (wide end) to 2.7 degrees (tele end). Digital Zoom enlarges the center of the subject by expanding each image in both the vertical and

horizontal directions. When 12× digital zoom is used, the number of effective picture elements in each direction reduces to 1/12 and the overall resolution deteriorates.

You can activate the zoom in the following two ways:

•By pressing the TELE or WIDE buttons on the Remote Commander.

•Using a VISCA Command

Using Standard Mode

Using Variable Mode

There are eight levels of zoom speed.

Direct Mode

Setting the zoom position enables quick movement to the designated position.

Digital Zoom ON/OFF

In these standard and variable Speed Modes, it is necessary to send a “Stop Command” to stop the zoom operation.

•The Zoom Mode supports a Combined Mode and a Separate Mode.

Combined Mode

This is the previously existing zoom method. After the optical zoom has reached its maximum level, the camera switches to Digital Zoom Mode.

Separate Mode

In this mode, Optical Zoom and Digital Zoom can be operated separately. You can use digital zoom magnification at any time from within any level of optical magnification.

Focus

Focus has the following modes, all of which can be set using VISCA Commands.

•Auto Focus Mode

The minimum focus distance is 10 mm at the optical wide end (extreme close-up settings with VISCA control) and 800 mm at the optical tele end (distance from the front end of the lens), and is independent of the digital zoom.

The AutoFocus (AF) function automatically adjusts the focus position to maximize the high frequency content of the picture in a center measurement area, taking into consideration the high luminance and strong contrast components.

- Normal AF Mode

This is the normal mode for AF operations.

- Interval AF Mode

The mode used for AF movements carried out at defined intervals. The time intervals for AF movements and for the timing of the stops can be set in one-second increments using the Set Time Command. The initial value for both is set to five seconds.

- Zoom Trigger Mode

When the zoom is changed with the TELE or the WIDE buttons, the pre-set value (initially set at 5 seconds) becomes that for AF Mode. Then, it returns to Manual Focus mode.

AF sensitivity can be set to either NORMAL or LOW.

- NORMAL

Reaches the highest focus speed quickly. Use this when shooting a subject that moves frequently. Usually, this is the most appropriate mode.

- LOW

Improves the stability of the focus. When the lighting level is low, the AF function does not take effect, even though the brightness varies, contributing to a stable image.

7

To avoid AF error from continuous 24 hour AF mode usage, daily initialization of lens system using the CAM_Initialize command is recommended.

The CAM_Initialize command takes less than 3 seconds to initialize the focus and zoom.

•Manual Focus Mode

MF (Manual Focus) has both a Standard Speed Mode and a Variable Speed Mode. Standard Speed Mode focuses at a fixed rate of speed. Variable Speed Mode has eight speed levels that can be set using a VISCA Command.

Will not stop by this command itself in Standard Speed Mode and Variable Speed Mode. To stop, a Stop command must be sent.

•One Push Trigger Mode

When a Trigger Command is received, the lens moves to adjust the focus for the subject. The focus lens then holds the same position until the next Trigger Command is input.

•Infinity Mode

The lens is forcibly moved to a position suitable for an unlimited distance.

•Near Limit Mode

Can be set in a range from 1000 (∞) to C000 (10 mm). The focus range is narrowed by excluding the unnecessary range.

White Balance

White Balance has the following modes, all of which can be set using VISCA Commands.

•Auto White Balance

This mode computes the white balance value output using color information from the entire screen. It outputs the proper value using the color temperature radiating from a black subject based on a range of values from 3000 to 7500K.

This mode is the default setting.

•ATW

Auto Tracing White balance (2000 to 10000 K)

•Indoor

3200 K Base Mode

•Outdoor

5800 K Base Mode

Basic Functions

•One Push WB

The One Push White Balance mode is a fixed white balance mode that may be automatically readjusted only at the request of the user (One Push Trigger), assuming that a white subject, in correct lighting conditions and occupying more than 1/2 of the image, is submitted to the camera.

One Push White Balance data is lost when the power is turned off. If the power is turned off, reset the One Push White Balance.

•Manual WB

Manual control of R and B gain, 256 steps each

Automatic Exposure Mode

The variety of AE functions, which allow video signal to output the optimum image for subjects from low light conditions to bright light conditions, are available.

AE – Shutter Priority

The shutter speed can be set freely by the user to a total of 22 steps – 16 high speeds and 6 low speeds. When the slow shutter is set, the speed can be 1/30, 1/15, 1/8, or 1/4 s. The picture output is read at a normal

rate from the memory. The memory is updated at a low rate from the CCD. AF capability is low.

In high speed mode, the shutter speed can be set up to 1/10,000 s. The iris and gain are set automatically, according to the brightness of the subject.

Basic Functions

AE – Manual

The shutter speed (22 steps), iris (18 steps) and gain (16 steps) can be set freely by the user.

AE – Bright

The bright control function adjusts both the gain and iris using an internal algorithm according to a brightness level freely set by the user. Exposure is controlled by gain when dark and by iris when bright. As both gain and iris are fixed, this mode is used when exposing at a fixed camera sensitivity. When switching from Full Auto or Shutter Priority Mode to Bright Mode, the current status will be retained for a short period of time.

Only when the AE mode is set to “Full Auto” or “Shutter Priority,” the user can switch it to “Bright.”

When switching from the Shutter Priority mode to the Bright mode, the shutter speed set in the Shutter Priority mode is maintained.

Spot Exposure Mode

In Full Auto AE, the level for the entire screen is computed and the optimum Auto Iris and Gain levels are determined. In Spot AE, a particular section of the subject can be designated, and then that portion of the image can be weighted and a value computed so that Iris and Gain can be optimized to obtain an image. For example, in an image with a lot of movement and with varying levels of brightness, portions without much change can be designated as such a “spot,” and changes to the screen can be minimized in that area. As shown in the diagram below, a range of 16 blocks vertically and 16 blocks horizontally can be designated.

In the case where the center is designated (shown in black), the level is computed along with a weighted value for the surrounding block (shaded), including the specified portions; and then the Gain and Iris are set. The value of the designated portions and the surrounding areas should be calculated as 90% and the rest should be set to 10%.

03	–4	–6 dB
02	–5	–7.5 dB
01	–6	–9 dB
00	–7	–10.5 dB

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 the text 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 the Slow Shutter is set to “Auto,” this ensures that the slow shutter is engaged automatically when the brightness drops. This occurs only when the AE mode is set to “Full Auto.”

“Slow Shutter Manual” is the factory setting.

ICR (IR Cut-Removable) Mode

An infrared (IR) Cut-Filter can be disengaged from the image path for increased sensitivity in low light environments. The ICR will automatically engage depending on the ambient light, allowing the camera to be effective in day/night environments.

If you normally set the IR Cut-Filter to OFF, the image will be black and white (monochrome).

10

Auto ICR Mode

Auto ICR Mode automatically switches the settings needed for attaching or removing the IR Cut Filter. With a set level of darkness, the IR Cut Filter is automatically disabled (ICR ON), and the infrared sensitivity is increased. With a set level of brightness, the IR Cut Filter is automatically enabled (ICR OFF). Also on systems equipped with an IR light, the internal data of the camera is used to make the proper decisions to avoid malfunctions.

Basic Functions

Note

When in Auto_ICR_OFF state and WB data is added (default), a malfunction may occur when the subjects largely consisting of blue and green colors are taken. Auto ICR is available in AE-full-auto state only.

Camera ID

The ID can be set up to 65,536 (0000 to FFFF). As this will be memorized in the nonvolatile memory inside the camera, data will be saved, regardless of the “position preset.”

Effect

It consists of the following functions.

•Neg. Art: Negative/Positive Reversal

•Black White: Monochrome Image

Others

IMAGE FLIP

The image output by the camera is flipped upside down, and the direction of Pan/Tilt movements are reversed using the IMAGE FLIP switch on the back of the unit.

Mirror Image

This function reverses the video output from the camera horizontally.

Freeze

This function captures an image in the field memory of the camera so that this image can be output continuously.

Because communication inside the camera is based on V cycle, the captured image is always the one 3V to 4Vs after the sending of a Command. Thus, you can not specify a time period after sending EVEN, ODD or a Command.

Power On/Off

Powers the camera on and off. When the power is off, the camera is able to accept only the lowest level of VISCA Commands and POWER of the Remote Commander; the display and other features are turned off.

I/F clear

Clears the Command buffer of the camera. Clearing the buffer can also be carried out from the control application software when the power is on.

Address set

VISCA is a protocol, which normally can support a daisy chain of up to seven attached devices. Therefore, whenever a camera is connected for the first time, be sure to use the address set to confirm the address.

11

Mute

Blanks the screen and sends out a synchronizing signal.

Lens Initialization

Initializes the zoom and focus of the lens. Even when power is already on, it initializes the zoom and the focus.

AutoPowerOff

If an operation is not attempted via either a VISCA command or the remote controller during a pre-set time period (from 1 to 65,535 minutes), the power will automatically turn off (Standby). To disable this function, set the time period to 0 minutes.

NightPowerOff

When the Alarm function operates in DayNight mode, and the unit judges that it is night, if an operation is not attempted via either a VISCA command or the remote controller during a pre-set time period (from 1 to 65,535 minutes), the power will automatically turn off (Standby). To disable this function, set the time period to 0 minutes.

When the DayNight level is set correctly (the Day level > the Night level), the Alarm function can only be set when the unit is operated in DayNight mode.

For information on DayNight mode settings, see pages 13, 14, and 24.

AutoPowerOff and NightPowerOff can be used at the same time.

However, if the criteria for both are fulfilled at the same time, the shorter of the two time periods until shut down will be used to turn the power off (Standby).

Memory (Position Preset)

Using the position preset function, 6 sets of camera shooting conditions can be stored and recalled.

This function allows you to achieve the desired status instantly even without adjusting the following items each time:

•Pan-Tilt position

•Zoom Position

•Digital Zoom On/Off

•Focus Auto/Manual

•Focus Position

•AE Mode

•Shutter control parameters

•Bright Control

•Iris control parameters

•Gain control parameters

•Exposure Compensation On/Off

•Exposure Level

•Backlight Compensation On/Off

Basic Functions

•Slow Shutter Auto/Manual

•White Balance Mode

•R/B Gain

•Aperture

•ICR Shoot On/Off

The settings are recalled when the power is turned on.

Basic Functions

Alarm Function

This function instructs the camera to detect movement within the monitoring area and then send an alarm signal automatically.

A High level signal is output when camera detects movement inside the monitoring area. A Low level signal is output when object stops moving.

However, when the mode is set to “DAY/NIGHT”, the High level signal is output for dark and the Low level signal is output for bright.

The Detect signal goes out through the serial command (VISCA) communication line.

Example

1.A door is motionless, so the Detect Level is Low.

2.At the moment when the door is opened by someone, the Detect Level goes to High.

3.The Detect Level is High while the shooting object is moving.

4.When the door is closed, Detect Level goes to Low again, or signals are output only once at the time of switching between High Level and Low Level.

00		Set the internal focus position. When focus movement is detected, the detect signal is High. When focus goes
		back to the previous position, the detect signal is Low.
01		Set a fixed period of time. When focus does not move during the time, the focus position is memorized as a
		rest position and the detect signal is Low.
		When focus moves, the detect signal is High. Afterwards when focus does not move for the fixed period of
		time, the focus position is memorized and the detect signal becomes Low.
02		Set the internal AE Level. When AE movement is detected, the detect signal is High. When AE Level goes
		back to the previous level, the detect signal is Low.
03		Set a fixed period of time. When AE Level does not change during this time, the AE value is memorized as a
		rest value and the detect signal is Low.
		When AE value changes, the detect signal is High.
		Afterwards when AE value does not change for the fixed period of time, the AE value is memorized and the
		detect signal becomes Low.
