Color or B&W Internal Video Assist for Aaton LTR (Reg16 or Super16)

The CCD image sensor and video assist electronics are mounted inside the camera body. The power necessary to supply the video assist is taken internally from the camera's 4 pin XLR power input receptacle. You can use an on-board battery in a regular way without an adapter. Our internal installation will give you a picture that is brighter than that of the external one because the CCD image sensor is installed closer to the beamsplitter.

Specificationsfor the color unit:

• SONY CCD image sensor
• Signal system: NTSC or PAL
• Picture elements: NTSC 768(H) x 494(V), PAL 752(H) x 582(V)
• Scanning system: NTSC - 525 lines, PAL - 625 lines, 2:1 interlace
• Horizontal resolution: 470 TV lines
• Min. illumination: 0.8 Lux, F1.2 AGC: ON
• BNC video output connector: 1.0 V p-p composite video at 75 ohm
• White balance (WB) control 2 position switch. When set to the lower position, the white balance is in auto mode (AWB is on). When set to the upper position, the white balance is in constant color temperature mode (CCT). The CCT mode remembers the last color palette that was set in the lower position (last palette in AWB mode); the palette will remain constant even if the color temperature of the light source changes. To calibrate the white level for a particular color temperature, you will need to put a white sheet of paper in front of the camera lens and set the switch to the lower position for about 3 sec. Then turn it to the upper position to activate the CCT mode. The color palette will be set after this procedure .
• AGC/CCD IRIS control switch: 3 position switch which controls the CCD IRIS and AGC on/off
  - Lower: AGC control is OFF (0dB) and CCD IRIS control is OFF
  - Middle: AGC control (max 14dB) is ON and CCD IRIS control is OFF
  - Upper: AGC control is OFF (0dB) and CCD IRIS control is ON
• LED power indicator
• Power on/off switch: when in upper position, the video power is ON and the red LED is lit; when in lower position, the video power is OFF and the red LED is not lit.
• Power requirement: 12 to 17V DC (from the camera's battery)
• Power consumption: 2.4 W (200mA/12V)

- the color unit with digital control:

• Power on/off switch (2 position):
  - Left: the video assist is ON and the red LED is lit.
  - Right: power is OFF and the red LED is not lit.

• Digital control by decimal switch:
  "0" - Auto Gain Control (AGC) is ON (gain max: 18 dB), and CCD IRIS is ON. This is the automatic exposure control setting.
  "1" - AGC is OFF (gain: 0 dB), and CCD IRIS is ON. Use this setting when the image is overexposed (bright light).
  "2" - AGC is ON, and CCD IRIS is OFF. Use this setting when shooting in low light.
  "3" - AGC is OFF, and CCD IRIS is OFF.
  "4" - Same as "0" but with back light compensation.
  "5" - Same as "1" but with back light compensation.
  "6" - Same as "2" but with back light compensation.
  "7" - Same as "3" but with back light compensation.
  "8" - Automatic exposure control, white balance setting.
  "9" - CCD IRIS is ON, white balance setting.

To calibrate the white level for a particular color temperature, you will need to put a white sheet of paper in front of the camera lens and set the decimal switch to "9" or "8" for about 3 sec. Then set it to "0" or "7", respectively. The color palette will be set after this procedure.

• CCD IRIS control on/off switch: upper position CCD IRIS control is ON, lower position is OFF. Set this control to ON when the image is overexposed (bright light)
• LED power indicator
• Power on/off switch: when in upper position, the video power is ON and the red LED is lit; when in lower position, the video power is OFF and the red LED is not lit.

• Power consumption: 1.4W (120mA/12V)

Flickerfree Color Integrated Video Assist for Aaton LTR

This flickerfree color video assist is designed to produce a flickerfree monitor image for camera speeds above 10 fps and gives you the best possible image (brightness and contrast) for the Aaton LTR camera because the high sensitivity EXview HAD CCD image sensor is mounted just behind the camera's pellicle beam splitter. All original AATON connectors are accessible. The on-board battery can be used only with a power adapter.

The flicker reduction switch (3 position):
- When set to the lower position, flickerfree mode FF is activated and the green LED is lit. This mode is designed to produce a 100% flickerfree video image for camera speeds above 10fps.
- When set to the middle position, flicker reduction is off and the green LED is not lit. The video assist is in normal mode.
- NTSC - When set to the upper position, flickerfree mode FF30 is activated and the green LED is lit. This mode provides the best possible 100% flickerfree image when operating at a camera speed of 29.97 fps or 30 fps. In this mode, flickering is reduced by 70% for camera speeds other than 29.97 fps and 30 fps.
PAL - When set to the upper position, flickerfree mode FF24/25 is activated and the green LED is lit. This mode provides the best possible 100% flickerfree image when operating at a camera speed of 24 fps or 25 fps.
Flickerfree modes FF , FF30 (NTSC) and FF24/25 (PAL) will only be active when the camera is running. Once the camera is stopped, normal mode will resume.

White balance switch (3 position):
- Lower: 5600K (fixed) - for outdoor shooting on sunny days.
- Middle: 3200K (fixed) - for indoor shooting under incandescent light.
- Upper: Auto White Balance is ON. The white balance is adjusted according to the color temperature transition of the subject. This mode is suitable for shooting with variable lighting.

Gain control switch (3 position):
- Lower: gain control is set to 0dB.
- Middle: gain control is set to 4dB.
- Upper: auto gain control (AGC) is ON.
