Optera Video Processor with Built-in LED Light Source

CV - 170

The Optera Video Processor CV-170 offers HDTV image quality and NBI (Narrow Band Imaging) which support maximizing diagnostic yield. Furthermore, long-life LED light source is incorporated in one design. The CV-170 achieves both more advanced diagnosis and lower running cost compared to any other conventional processor.

Key Benefits:-


HDTV imaging capability provides the best possible image quality for endoscopes, enabling observation of capillaries, mucosal structures, and other patterns.

NBI (Narrow Band Imagining)

NBI (Narrow Band Imaging) enhances the visibility of capillaries and other structures on the mucosal surface.

LED Light Source

Newly adopted long-life LED light source minimizes lamp replacement, while reducing energy and noise.

Pre-freeze Function

The pre-freeze function selects the clearest still image automatically. It may help to save time and eliminate the physician’s frustration.

Structure Enhancement

Two types of structure enhancement are available – mainly, the conventional Type A is ideal for observation of larger mucosal tissues with high contrast in the lower gastrointestinal tract, while the new Type B is suitable for observation of vascular tissues in the upper gastrointestinal tract.

Portable Memory Compatibility

Portable memory (MAJ-1925) is compatible, which is the standard for data management. Simply connect and upload.

Compatible with existing scopes

Compatible with EVIS 100/130/140 Series, Actera 150 Series, EVIS EXERA 160 Series, EVIS EXERA II 180 Series and GI/BF/VISERA Series scopes.
*Please note that there are some exceptions.

Variety of signal output options

16:9 and 16:10 output for a HDTV monitor is available. Compatible with analog, HD-SDI, and DVI output.

Digital signal output HD-SDI (SMTPE 292M), SD-SDI (SMPTE 259M) and DVI (WUXGA, 1080p or SXGA) can be selected.
White balance adjustment White balance adjustment is possible using the white balance button on the front panel.
Standard color chart output The “Color bar” or the “50% white” screen can be displayed.
Color tone adjustment The following color tone adjustments are possible.

  • Red adjustment: ±8 steps
  • Blue adjustment: ±8 steps
  • Chroma adjustment: ±8 steps
Automatic gain control (AGC) The image can be electronically amplifi ed when the light is inadequate due to the distal end of the endoscope being too far from the object.
Contrast The image contrast can be set to one of the following three modes (N, H, L).

  • N (Normal): Normal image
  • H (High): The dark areas are darker and the bright areas are brighter than in the normal image.
  • L (Low): The dark areas are brighter and bright areas are darker than in the normal image.
Noise reduction Noise is corrected by image processing.
Iris The auto iris modes can be selected using the “iris mode” switch on the front panel.

  • Peak: The brightness is adjusted based on the brightest part of the endoscopic image.
  • Average: The brightness is adjusted based on the average brightness of the endoscopic image.
Image enhancement setting Fine patterns or edges in the endoscopic images can be enhanced electrically to increase the image sharpness.
Either the structural enhancement or edge enhancement can be selected according to the user setup.

  • Structural enhancement: Enhancement of contrast of the fine patterns in the image.
  • Edge enhancement: Enhancement of edges of the endoscopic image.
Switching the enhancement modes The enhancement level can be selected from 3 levels (1, 2, and 3).
Image size selection The size of the endoscopic image can be changed using the “IMAGE SIZE” key on the keyboard.
Freeze An endoscopic image is frozen using an endoscope or the “FREEZE” key on the keyboard.
Pre-freeze The image with the least blur is selected from the images captured in the set time period before freeze operation and displayed.
NBI observation This is one of optical-digital observations using the narrow band observation light.
