Basic Functions

Overview of Functions

VISCA commands are the basis of camera control.

Timing Chart

As VISCA Command processing can only be carried out one time in a Vertical cycle, it takes the maximum 1V cycle time for an ACK/Completion to be returned. If the Command ACK/Completion communication time can be cut shorter than the1V cycle time, then every 1V cycle can receive a Command.

In general

• 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; the display and other features are turned off.

• I/F clear

Clears the Command buffer of the EX780S/SP. 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. However, the FCB-EX780S does not support connection of cameras in a daisy chain. Therefore, whenever a camera is connected for the first time, be sure to use the address set to confirm the address. The EX780S does not support connection of cameras in a daisy chain. However, whenever a camera is connected for the first time, be sure to use the address set to confirm the address.

• ID Write

Sets the camera ID.

• Mute

Blanks the screen and sends out a synchronizing signal.

• Lens Initialize

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

• Comp Scan

A pixel blemish-masking feature, which can be made to reevaluate overall CCD pixel blemishes and mask severely flawed pixels automatically upon receiving the COMP SCAN command. This feature helps to mask the flaws found in CCD imagers, even after the camera has been powered on for some time.

Basic Functions

Zoom

The EX780S/SP employs a 25× optical zoom lens combined with a digital zoom function; this camera allows you to zoom up to 300x.

• Optical 25×, f = 2.4 to 60 mm (F 1.6 to F 2.7)

The horizontal angle of view is approximately 45 degrees (wide end) to 2.0 degrees (tele end). Digital Zoom enlarges the center of the subject by expanding each image in both the vertical and horizontal directions. When 300× zoom is used, the number of effective picture elements in each direction

reduces to

/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 camera itself

• 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 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.

- Normal AF Mode

This is the normal mode for AF operations.

- Interval AF Mode

The mode used for AF movements carried out at particular 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 stops.

AF sensitivity can be set to either HIGH or LOW.

- HIGH

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.

When used for 24 hours continuously, initialization of lens system once a day is recommended because this will make the life of lens longer. The Initialize Lens Command takes a little less than 3 seconds to initialize the focus and zoom.

• Manual Focus Mode

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.

• One Push Trigger Mode

When a Trigger Command is sent, the lens moves to adjust the focus for the subject. The focus lens then holds that 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 (35 mm).

• Auto Focus Mode

The minimum focus distance is 35 mm at the optical wide end and 800 mm at the optical tele end, and is independent of the digital zoom. The AutoFocus (AF) function automatically adjusts the focus position to maximise the high frequency content of the picture in a center measurement area, taking into consideration the high luminance and strong contrast components.

Basic Functions

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 factory setting.

• ATW

Auto Tracing White balance (2000 to 10000 K)

• Indoor

3200 K Base Mode

• Outdoor

5800 K Base Mode

• 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 One Push White Balance.

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 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,” can you 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%, the rest should be set to 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.

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.

When Auto Slow Shutter is ON

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 red colors are taken.

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.

Basic Functions

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.

Effect

It consists of the following functions.

• Neg. Art: Negative/Positive Reversal

• Black White: Monochrome Image

Others

Mirror image

The video output from the camera can be reversed left and right using this function.

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.

The Image Stabilizer Function

When the Image Stabilizer Function is ON, it helps in obtaining a stable image free of vibration caused by jarring movements. For a vibration frequency of around 10 Hz, correction is approximately 90%.

Note

Be advised that, when using systems equipped with Pan and Tilt functions, quick starts and stops are corrected for, causing a different movement from that of the normal image.

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.

• 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

• Slow Shutter Auto/Manual

Custom Preset

As with the positon preset function, the camera shooting conditions can be stored and recalled. The settings are recalled when the power is turned on. For setting items, refer to the “Initial Settings, Custom Preset and Backup” section on page 13.

Privacy Zone Settings

For subjects requiring special treatment due to privacy issues, designated areas of the image can be masked from view. In this situation, an area can be masked using Privacy Zone settings. As shown in the diagram below, 12 blocks vertically and 16 horizontally, in a maximum of 6 places, can be masked.

Synchronization methods

Internal and external synchronization are available; VISCA Commands allow you to switch between them.

• Internal synchronization

An internal vibrator inside the camera generates a synchronizing signal as a basic oscillator. NTSC=28.636363MHz PAL=28.375MHz

• External synchronization (V-Lock Synchronization)

When a TTL level V-Lock pulse is input, the camera synchronizes to the input signal (V-lock synchronization). The frequency of the input signal synchronizes to within ±1Hz of the external synchronization. Also, V-Phase phase adjustment can be carried out to within ±90 degrees due to the V-Lock phase adjustment. In addition, 360 degree phase adjustment is possible because you can switch between 0 degree and 180 degree phases.

Because V-Lock synchronization is a simple synchronization method, color signals like a VBS “GenLock” cannot be synchronized.

Note

Cannot be displayed together with Privacy display.
