Olympus EVIS EXERA III CV-190 Video System Center (Video Processor)

The Olympus EVIS EXERA III CV-190 is a video system center (video processor) that provides video processing for advanced endoscopy and easy access to EVIS EXERA III endoscope features.
It delivers improved image processing with reduced noise and halation and improved color contrast for clearer visualization.
Narrow Band Imaging (NBI) on the EVIS EXERA III 190 Series is designed for significantly increased brightness and up to twice the viewable distance in the lumen versus prior generations.
Pre-Freeze automatically selects the sharpest still image to improve still capture efficiency.
For your monitors and recording infrastructure, the CV-190 supports multiple outputs including HD-SDI, DVI, DV (IEEE 1394), and analog HDTV/SDTV.

Why clinicians choose the CV-190

Image quality improvements that matter in the procedure room

• Enhanced color reproduction, minimized image noise, and reduced halation for improved image quality.

• Brighter NBI performance (system feature description) designed to increase usable viewing distance.

Still-image capture made easier

• Pre-Freeze automatically selects the clearest still image from moments before the freeze action.

Workflow and ergonomics

• Picture-in-picture and index functions to support observation and room ergonomics.

• One-touch connection design (waterproof connector) that enables one-step connection to the light source and avoids a separate scope cable for the video processor.

Outputs and connectivity

Choose the signal path that fits your monitors and documentation stack.

HD / SD signal outputs (manufacturer listed):

• Analog HDTV: RGB or YPbPr (1080i NTSC/PAL)

• Analog SDTV: composite (VBS), Y/C, RGB (NTSC/PAL), including simultaneous outputs

• Digital: HD-SDI (SMPTE 292M), SD-SDI (SMPTE 259M), DV (IEEE 1394), DVI (WUXGA/1080p/SXGA)

• 16:9 and 16:10 formats for HD monitors

Device linking / expandability (manufacturer listed):

• Link connection to peripheral devices to simplify cabling and accelerate transmission speed; Olympus documentation system supports networking expandability.
