Overview of Functions

Zoom

The SRG camera employs a 30× optical zoom lens combined with a digital zoom function; this camera allows you to zoom up to 360×. SRG-201SE employs 20× optical zoom lens. If you use digital zoom, it allows you to zoom up to 240×.

• Optical 30 (F 1.6 to F 4.7)

• SRG-201SE employs 20 to 111.8 mm (F 1.6 to F 4.5)

Digital Zoom enlarges the center of the subject by expanding each image in both the vertical and horizontal directions. When the digital zoom is used, the resolution deteriorates.

You can activate the zoom in the following modes, all of which can be set using VISCA command.

Standard Mode Variable Mode

There are eight levels of zoom speed.

In these standard and variable modes, it is necessary to send Stop Command to stop the zoom operation.

Direct Mode

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

Digital Zoom ON/OFF

×, f = 4.3 mm to 129 mm

× optical zoom, f = 4.3 mm

Focus

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

• Auto Focus Mode

The Auto Focus (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.

The minimum focus distance is 10 mm at the optical

wide end and 1200 mm at the optical tele end.

- 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, the AF mode activates for the pre-set time. Then, it stops. The initial value is set to 5 seconds.

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.

Basic Functions

• Manual Focus Mode

Manual Focus has both a Standard Mode and a

Variable Mode. Standard Mode focuses at a fixed rate of speed. Variable Mode has eight speed levels that can be set using a VISCA Command.

In these standard and variable modes, it is necessary to send Stop Command to stop the zoom operation.

• 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 F000 (1 cm). Default setting: D000h (30 cm)

White Balance

White Balance has the following modes.

• 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 2500K to 7500K.

This mode is the factory setting.

• ATW

Auto Tracing White balance (2000K to 10000K)

• Indoor

3200K Base Mode

• Outdoor

5800K Base Mode

• One Push WB

One Push White Balance is a function that forcibly

captures the white color once the lighting conditions to illuminate the subject are set, enabling you to shoot the image in the conditions as they are set. By using this function, the natural color of the subject can be obtained without being affected by the surrounding lighting conditions. To set this mode, shoot the subject that you want to capture the white color and send the One Push White Balance Trigger.

Automatic Exposure Mode

A variety of AE functions are available for optimal output of subjects in lighting conditions that range from low to high.

• Full Auto

Iris, Gain and Shutter Speed can be set automatically.

• Gain Limit Setting

The gain limit can be set at the Full Auto, Shutter

Priority, Iris Priority, Bright and Manual in the AE mode. Use this setting when image signal-to-noise ratio is particularly important.

• Shutter Priority

AE – Manual

The shutter speed (22 steps), iris (14 steps) and gain (15 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,” you 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.

Defog mode

When the surrounding area of the subject is foggy and low contrast, the defog mode will make the subject appear clearer.

Basic Functions

Wide Dynamic Range Mode (WD)

The Wide Dynamic Range mode is a function for dividing an image into several blocks and correcting blocked-up shadows and blown-out highlights in accordance with the intensity difference. It enables you to obtain images in which portions ranging from dark to light can be recognized, even when capturing a subject with a large intensity difference that is backlit or includes extremely light portions. Images with wide dynamic range are produced by combining long-exposure signals (normal shutter) with the signals of the high-intensity portions obtained with a short exposure (high-speed shutter).

• About WD Set Parameter (Command: 8x 01 7E 04 00 0p FF)

p: WIDE D (Wide dynamic range mode) When MODE (exposure mode) is set to FULL

AUTO, the camera distinguishes light and dark areas in the same scene, adjusts the brightness for dark areas, and also controls the blown out highlights.

You can select the wide dynamic range mode

from among OFF, LOW, MID and HIGH.

(0: OFF, 1: LOW, 2: MID, 3: HIGH.)

Notes

• You can set the wide dynamic range mode when the WIDE D is set to FULL AUTO only.

• When the WIDE D is not set to OFF, the MODE setting is fixed at FULL AUTO.

• When changing the WIDE D, the luminance change of the screen occurs for a moment.

• When the change of exposure is big, the screen may stop for a moment.

• When the wide dynamic range mode is ON, false colors may appear in some parts of the image. This phenomenon is unique to wide dynamic range mode, and is not an indication of a camera malfunction.

• When switching wide dynamic range mode, images are shown at a maximum of 8 frames at the same time.

• When the intensity difference of the image is small, there is no difference in effect between MID and HIGH.

Exposure Compensation

Exposure compensation is a function which offsets the internal reference brightness level used in the AE mode, by steps of 1.5 dB. The reference brightness is 0.

Setting value

High Resolution Mode

This mode enhances edges and produces higher definition images.

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.

Noise Reduction

The NR (Noise Reduction) function removes noise (both random and non-random) to provide clearer images. This function has six steps: levels 1 to 5, plus off. The NR effect is applied in levels based on the gain, and this setting value determines the limit of the effect. In bright conditions, changing the NR level will not have an effect.

Basic Functions

High Sensitivity Mode

In this mode, higher sensitivity gain is applied as standard gain increases, reaching a gain level at MAX gain of up to 4x the standard gain. In such cases, however, there will be a high volume noise in the image.

Gamma Mode

In this mode, the gamma can be set to ON/OFF. 0: Standard 1: OFF

Image Stabilizer

You can set this function to ON or OFF. When set to ON, you can obtain steadier images if vibration is present. This stabilizer is effective for vibration frequencies around 10 Hz. This function utilizes digital zoom; therefore, the angle of view and resolution of images may be affected. However, image sensitivity is retained. OFF: The image stabilizer function is not effective

operations.

ON: The image stabilizer function is effective

operations.

Notes

• The image stabilizer function is not effective during pan/tilt operations. It may take some time for the image to stabilize after performing pan/tilt operations.

• If the image stabilizer function is enabled, it may take some time for the image to stabilize after turning on the power of the camera.

• Depending on the installation conditions, the image stabilizer may not be effective.

• When the image stabilizer function is set to ON, the field angle is shifted to the direction in which the subject appears larger.

• The image stabilizer may not be effective in an installation environment where high frequency vibration is present. In this case, set the image stabilizer function to OFF.

Auto Slow Shutter On/Off

Low-Illumination Chroma Suppress Mode

You can configure a chroma suppress mode for lowillumination conditions. This can be useful when color noise is particularly noticeable in such conditions. Four levels (disabled and three levels) are available for the low-illumination chroma suppress mode.

ICR (IR Cut-Removable) Mode

The IR Cut-Filter can be disengaged, by which the sensitivity in the infrared range is increased, allowing the camera to capture the image in darker area. When the auto ICR mode is set to ON, the image becomes black and white.

Color Gain

You can configure the color gain. Use this setting when bright color is particularly important. The initial setting 100% (4h) can be set to range from approx. 60% (0h) to 200% (Eh) with 15 stages.

Color Phase

You can configure green, yellow, red, magenta, blue and cyan individually. The initial setting 0 degrees (7h) is adjustable between approx. −14 degrees (0h) to +14 degrees (Eh), in 15 increments.

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. Auto ICR Mode operates with the AE Full Auto setting.

When set to “On,” the slow shutter functions automatically when the light darkens. This setting is available only when the AE mode is set to “Full Auto.” The default setting is “Auto Slow Shutter Off.”

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.

Picture Effect

It consists of the following functions.

• Neg. Art: Negative/Positive Reversal

• Black & White: Monochrome Image

Others

I/F Clear

Clears the Command buffer of the camera. The buffer is cleared even during the power on state using the control software.

Address Set

VISCA is a protocol, which supports a daisy chain of up to seven connected cameras via RS-422 interface. In such cases, the address set command can be used to assign addresses from 1 to 7 to each of the seven cameras, allowing you to control the seven cameras with the same personal computer. Be sure to use the address set command to set the address whenever a camera is connected for the first time.

Note

Depending on the information such as brightness, etc., in the ON/ OFF settings condition, a malfunction may occur when the subjects largely consisting of blue and green colors are taken.
