2.2 PACKAGE CONTENTS

This product is delivered with its accessories in a carrying case.

For a smooth workflow, please check if the set is complete before going on production. If one of these

items gets lost, feel free to order it at WIGE MEDIA AG.

Contents:

1x CUNIMA MCU[2] HD-camera

1x Power Supply CUNIMA MCU[2]

1x Device Cable for Power Supply

1x Adaptor Fischer to XLR 7-pole (connection camera to power supply)

1x Adaptor Tripod (1/4 inch and 3/8 inch screws)

3. SETUP

Please notice that due to safety reasons this camera system may only be operated by trained staff!

3.1 CAMERA SETUP

1. Open the carrying case and check if all needed items are included (see chapter 2.2).

2. Remove the power supply and connect it with the cable device to a power source (220V-

240V). The blue LED on the power supply should lighten up.

3. Connect the camera to the power supply by using the adaptor ‘Fisher to XLR 7-pole’.

4. The captured image should appear at the BNC connector of the camera within seconds and

can then be finished. The setup is now completed and the camera ready for use.

Please note: do not turn the connectors when pulling out the Fisher-cable. To disconnect,

please just remove the cable by pulling straight. Turning it out with force may cause bended

connectors and lead to irreparable damage.

3.2 CONNECTORS OF THE CUNIMA

3.3 LENS SETUP

The C-Mount screw is a socket to hold applicable lenses. In some cases, an adaptor-coil is needed to

ensure the correct flange back. This is not exceptional, but a current way to counteract imprecise

manufacturing.

3.2.1. Choosing a lens

Independent of the focal length, there is an important characteristic of C-Mount lenses which should

be considered when choosing a lens. Because of the existence of different sensor dimensions (1/3

inch, ½ inch and2/3 inch) and senor quantities (3x ½ inch or 1x 2/3 inch etc.) and the fact that the

Cunima MCU[2] does contains single CMOS sensor with Beyern-pattern, please only use lenses

which are engineered for that indented purpose (CUNIMA: 2/3 inch single CMOS sensor).

3.2.2. C-Mount thread

1. Please remove the rubber protection of the Cunima MCU[2]. You can see the C-Mount thread

now. Please note that behind the thread is the glass protection of the sensor. This glass

should not be damaged or it may constrain the image quality.

2. Remove the lens and check for possible damages. Please do never mount a damaged lens on

the Cunima MCU[2]. Further damages of the camera because of optical small parts like glass

splinters could occur.

3. Screw the lens into the C-Mount.

4. If the flange back of the lens is not right, you may use the backfocus (see chapter 3.4)

adjustment feature of the CUNIMA MCU [2].

Whenever there is no lens screwed on the C-Mount, please make sure that a protection

rubber protects the cameras glass filters to avoid any damages!

3.4 BACKFOCUS ADJUSTMENT

To ensure that you can use every lens with this camera properly,

the housing of the CUNIMA lets you adjust the backfocus.

To adjust the backfocus, please follow the instructions below:

rotate the gearwheel clockwise to increase the

backfocus

rotate the gearwheel counterclockwise to

decrease the backfocus

3.5 IRIS/FOCUS MOTOR

3.5.1 INSTALLATION

1. To use the iris/focus motor on the CUNIMA, mount it on any of the four sides of the

camera. The two threads on each side of the head of the CUNIMA can be used to fix it.

Make sure to align the gearwheel of the motor with the gearwheel of the lens properly.

2. Connect one male 7Pin plug of the Y-patch cable to the CUNIMA and the other to the

iris/focus remote module.

3. Now connect both parts with the female connector of the y-patch cable to the standard Y-

cable of the CUNIMA and establish the connection to the power supply and the RCP.

4. The green LED of the iris/focus remote module will now flash slowly. This indicates that

the remote module is ready to work. If the green LED stays is illuminated constantly

without flashing, reboot the remote module by pulling out the cable and plugging it back in.

3.5.2 CONNECTION DIAGRAM

3.5.3 OPERATION

You can use the RCP to control the iris/focus motor. Navigate to "IRIS" in the RCP Menu and spin the

MASTER Encoder (see chapter 5) on the right, to open or close the iris.

3.6 INTER CAMERA COMMUNICATION (ICC)

The inter camera communication is especially developed for 3D purposes. With this feature you are

able to sync two CUNIMA MCU [2] internal. This method for syncing both cameras is extremely exact

because one pixel on one sensor is synced with the exact same pixel on the other sensor.

To use the ICC, please follow the instructions below:

1) Connect both cameras with a 9-Pin fischercable

2) Set one Camera to SYNCMODE = MASTER

3) Set the other Camera to SYNCMODE = SLAVE

Now both cameras should be synced.

If anything went wrong, please restart the cameras by pulling the powerplug out of the camera.

Every camera restarts in SYNCMODE=NORMAL.

3.7 CLEANING OF THE CAMERA

The metal body of the Cunima MCU[2] can be cleaned with a cleaning cloth. By trend the body is not

very susceptible to damage, which makes the cleaning very easy.

Optical parts like glass protections and lenses can be polished with a dry microfiber lens cloth.

We can not be liable or give any guarantee services for damages caused through cleaning of the

camera with aggressive cleaning agent.

PERATIO

4. OPERATION

In this chapter, there are control modes presented and explained in a detailed way.

4.1 ANALOG GAIN

The analog image intensifier reads the CMOS image sensor and produces high quality results by

boosting the brightness in case of low light situations or especially by reducing the sensor-sensitivity to

avoid overexposure in situations with too much light. The adjustments cause changed image noise

behaviour, which is mostly not seen explicitly until higher intensifier levels (+21, +24).

Cunima MCU[2] offers these analog gain levels:

0 – 24dB in 3dB steps

3dB for example corresponds to a half stop of light intensity. 6dB represents one full f-stop.

Intensifying above 18dB could cause strong noises.

We recommend to run the camera in 6dB or 9dB analog gain for broadcast environments and 0dB for

feature film.

4.2 EDGE ENHANCEMENT

When an image is read by an image sensor, the result is naturally dim. Only a digital edge

enhancement will adjust it to our viewing habits by making the image sharper. For this purpose the

edge enhancement algorithm is implemented.

The digital edge filter finds all the horizontal and vertical edges (x and y direction) in the image and

sharpens them.

The digital edge enhancement can be adjusted between 0 and 50.

The standard adjustment of the Cunima MCU[2] is set on 12, which is very useful for live-broadcast in

4:2:2 HDSDI. If you intend to record images for digital cinema with professional post-production, we

advise you to disable the edge enhancement so that it can be arranged in post.

4.3 FIXED PATTERN NOISE CORRECTION

Digital CMOS image sensors have a pattern noise. This stationary pattern may be seen under certain

circumstances (light setups) as vertical bars. The fixed pattern noise correction is supposed to delete

these bars.

Auto Correction:

The auto correction is recommended. The fixed pattern noise gets identified automatically and

corrected “on the fly”. If enormous fixed pattern noise can be seen in the image it should be gone in

less than 10 seconds. If you need a faster correction, use the manual correction.

Manual correction:

To perform the correction manually, you have to shade the image completely. It is advisable to put the

cap on to the lens to stop any light invasion.

After that, use the RCP to perform the FPN correction what takes less than half a second.

The correction is dependent on the Gain adjustments. If you change these adjustments, you should

renew the correction.

4.4 GAMMA CORRECTION

So that an image is recorded like the human eye expects the reproduction, you can change the

Gamma-curveinterpretation and with that adapt the reproduction to the human needs.

For this, you have the following gamma-options:

REC 709 - Standard-adjustment. For conditions according to broadcast-industry

standards.

Linear - Builds a linear Gamma-curve. Hence is not corrected for the reproduction on

commercial screens and seems often too dark.

User Gamma - Gives the user the possibility to change Gamma-parameters individually. The

parameters are Gamma-black (black level), Gamma-white (white level) and

Knee (falling gradient of white). The manipulation of these adjustments can

avoid a too strong white or a too poor presentation of black.

4.5 SHUTTER SPEED / EXPOSURE TIME

The Cunima MCU[2] camera with its CMOS image sensor scans the image linear. Hence it is the

electronic pendant to a rolling shutter.

Through the exposure time of the image you can manipulate the shutter speed and consequently the

picture.

You can choose an exposure time between 100% and 5%.

If you correct the exposure time, you get the following results in your picture:

By reducing the exposure time, the image becomes darker and the motion blur is reduced more and

more, what can be a win for recording fast content like sports.

The exposure time basis can be obtained by calculating 1/x. With a framerate of 50fps interlaced (for

example 1080i50) you get an exposure time of 1/50 by 100%. If you then reduce this integration time

to 50%, you get an exposure time of 1/100. Thus you lose the half of the incoming light, that means

one stop of light and the motion blur is reduced by 50% as well.

With a framerate of 25fps progressive (for example 1080p25) you get an exposure time of 1/25 by

100%. If you then reduce this integration time to 50%, you get an exposure time of 1/50. Hence, like

explained in the other example, you lose the half of the incoming light, that means one stop of light

and the motion blur is reduced by 50%, too.

4.6 OPERATION MODE

Next to the normal color operation mode in HSDSI (4:2:2), Cunima MCU[2] offers an uncompressed

RAW format.

There are following modes:

4.6.1. Color Mode

This is the standard mode. The camera starts in this one and is mainly used this way. At the exit of the

camera is a HDSDI signal in 4:2:2 compression. Recommended for broadcast applications.

4.6.2. RAW Format

In this mode, you get a special format with 12Bit data in a 20Bit data stream at the HDSDI exit. This

data can be recorded – with equipped recorders like the Megacine from MikroM – and converted in

12Bit/16Bit image data. Therefore you get a completely uncompressed video signal, which is

especially useful for special effects (keying and compositing) and for inserts in film material.

With the RAW format, an additional stop contrast range is added to the image.

4.7 IMAGE RESOLUTION - SCANNING FORMAT

Cunima MCU[2] supports all current broadcast-formats and several cinema formats.

The camera can be used worldwide and support all common framerates.

A distinctive feature is the display of these modes, because all scanning modes are based upon native

scans. So it does not scale the images and in smaller resolutions than 1080i, only a window of the

sensor is used. The CMOS sensor offers up to 2k resolution.

This way, it is possible to make images without scaling and the associated time loss and no need for

an external camera control unit (CCU) available.

5. RCP - REMOTE CONTROL PANEL

RCP – REMOTE CONTROL PANEL

For a flexible control of one or more cameras without computer support, there are two different remote

control panels available. The main difference between them is the operation mode and the quantity of

cameras to be controlled.

The RCP64 can control any amount of cameras, while the RCP4 is limited to two cameras.

In the following the RCP4, which is developed for mobile occasions, is explained.

5.1. INTRODUCTION

Controls up to 2 CUNIMA MCU[2] cameras.

5.2 INSTALLATION

With every RCP, a 7pol Fisher Y-cable is delivered. It connects the power supply with the camera and

with the RCP, so that the control panel has power and is connected to the RS 485 serial interface of

the Cunima MCU[2].

Connector Camera 1

Connector Camera 2

Please note to not turn the wires when pulling out the

Fisher cable out of the connector.

5.3 OPERATION

Cursor

Screen

MASTER Encoder

Controller for RED

Controller for GREEN

Controller for BLUE

Controller for black level of RED

Controller for black level of GREEN

Controller for black level of BLUE

The Operation of the Panel is separated in options, which navigate through the menu, and in direct

controller (4.-9.).

The menu can be navigated with the cursors (up) and (down)

A changing of an adjustment in the menu can be done with (left) and (right)

6.4 MENU

The following menu items provide you access

to all supported CUNIMA features (based on RCP Firmware 4.5):

Select camera

Selects between the control of the connector 1 and 2 on the right side of the control panel.

Paint Color & Saturation

Paints the color values in red, green and blue from -255 to 255. ‘0’ is the ‘standard value’.

With the selector ( control 3) you can control the saturation 0 (black and white ) up to 4000.

Standard value saturation is 2100.

Paint Black & master black

Paints the black values in red, green and blue from -255 to 255. ‘0’ is the ‘standard value’.

With the selector ( control 3) you can control the master black from 08 – 255.

Analog Gain

Sets an analog gain. Range is 0dB to 24dB in 3dB steps. Every 6 dB is equivalent to 1 f-stop

and 3 dB is ½ f-stop.

Gamma Mode

Set the current gamma curve.

Values are: off, REC 709, USR

REC 709 is recommended, but for feature films a linear gamma (off) could be right choice

(depends on post production needs).

The menu item user gamma (USR) enables the following features:

Gamma Black

Defines the black point (dark values) on the gamma curve.

Range: 0-64

GAMMA White

Defines the white point (bright values) on the gamma curve.

Range: 0-128

GAMMA Knee

Sets the knee point on the gamma curve, which is the angle of the connection between the

gamma black and white point on the curve.

Range: 0-64

Format

The Cunima camera is a multi format scanning camera, that provides most scanning formats

for broadcast and feature films worldwide.

The following scanning formats are available:

720p60; 720p50; 720p59,94;

1080i60; 1080i50; 1080i59,94;

1080p30; 1080p25; 1080p24; 1080p23,97; 1080p29,97

PAL 4:3, PAL 16:9; NTSC 4:3; NTSC 16:9

Detail & Focus

Detail is a detailing algorithm that gives you more sharpness in the image.

Range: 0-50

Recommendation for broadcast: 12

The focus value gives you information about how sharp your image is. The higher the value,

the sharper the image.

Integration Time

The integration time sets the shutter speed of the camera. 100% is a shutter speed of

1/framerate. So, a 1080p25 resolution/framerate is 1/25 on 100% shutter.

50% shutter is 1/50

25% shutter is 1/100

12% shutter is 1/200

6% shutter is 1/400

Half the shutter means 1 f-stop less light.

White Mode

Auto White Balance, but not implemented, yet.

Color Mode

Values: COL, B/W, RAW

COL: sets the ‘normal’ color mode.

B/W: sets the black and white mode, all color values get desaturated.

RAW: The CUNIMA camera provides you a RAW format with absolutely no changes on the

image. That format is a black and white image with a Bayer-Pattern and needs to be

debayered in post production. If you use this format make sure to use completely

uncompressed recorders only. Otherwise your Bayern-Pattern and the final image will be

destroyed.

Sync Mode

Via Bi-Level and Tri-Level Sync.

Values: Normal, Master, Slave

Normal: Camera is syncable with external sync-sources.

Master, Slave: Settings for ICC (see chapter 3.6)

Genlock IN

Values: Analog, Digital

Defines the Genlock signal that's selected to sync the camera.

Analog is an analog Black Burst (BB),

Digital defines a Tri-Level Sync.

Fixed Pattern Noise

CMOS imager always have some fixed pattern noise that needs to be corrected. Therefore the

imager provides two different algorithms to reduce fixed pattern noise.

Values: Manual, Auto

Manual: To use the manual fixed pattern noise correction, cover the lens to make sure the

camera only gets a totally dark (black) image. Then press the button of your cursor to start the

correction. That only takes milliseconds to execute.

Auto: The Auto algorithm is recommended, because it is working on the image all the time, to

avoid fixed structures on the image. As long as this feature is selected you won`t recognize

any fixed pattern noise in the image.

Reset

By pressing the cursorbutton, the camera will be reseted. This will help in cases of incorrect

communication between the camera and the RCP.

Set Output

Values: SDI

Iris

Values: 000 - 099

000: iris is completely closed

099: iris is completely opened

Focus

will be included in future versions
