CV-290

EVIS LUCERA ELITE Processor

The EVIS LUCERA ELITE Video System Centre CV-290 enables easy access to the range of advanced features incorporated into EVIS LUCERA ELITE endoscopes.

Key benefits

Ground-breaking resolving power for efficient diagnosis

Olympus is proud to introduce Dual Focus – a unique optical imaging technology enabling detailed examination of mucosal changes at the touch of a button when connecting HQ290 endoscopes

Brighter, more powerful Narrow Band Imaging

Narrow Band Imaging in EVIS LUCERA ELITE now delivers significantly increased brightness and contrast. Previously widely accepted as a tool for characterisation, the improved brightness may open new possibilities for lesion detection.

Outstanding, true-to-life image quality

EVIS LUCERA ELITE offers true-to-life HD endoscopic images of breath-taking clarity, delivering the optimum support for accurate diagnosis

The EVIS LUCERA ELITE Video System Centre CV-290 enables easy access to the range of advanced features incorporated into EVIS LUCERA ELITE endoscopes. A range of improvements assist in obtaining endoscopic images with maximum diagnostic yield whilst advanced Picture-in-Picture functions improve ergonomics in the endoscopy room.

Dual Focus
Dual Focus, a unique Olympus innovation on HQ scopes, is an innovative two-stage optical system enabling the user to switch between two focus settings. With the simple push of a button, the desired observation mode can be selected: “near mode” featuring ground-breaking resolving power for close mucosal observation or “normal mode” for standard observation.

Brighter and higher contrast Narrow Band Imaging
NBI in EVIS LUCERA ELITE offers a significantly increased viewable distance compared to previous generations. The improved contrast combined with this increased brightness means that NBI opens new possibilities in assisting you in lesion detection and characterisation.

Improved image processing
New and improved image processing delivers outstanding image quality thanks to reduced noise, reduced halation and improved colour contrast. The result: the optimum in image quality.

Classification (medical electrical equipment)Type of protection against electric shockClass I
 Degree of protection against electric shock of applied partTYPE BF applied part. Where no classification mark appears, the device is a TYPE BF applied part.
 Degree or protection against explosionThe video system center should be kept away from flammable gases.
ObservationAnalog HDTV signal outputEither RGB (1080/60I) or YPbPr (1080/60I) output can be selected. (For 100-240 V models)
Either RGB (1080/50I) or YPbPr (1080/50I) output can be selected. (For 220-240 V models)
 Analog SDTV signal outputVBS composite (480/60I: NTSC), Y/C (480/60I: NTSC), and RGB (480/60I: NTSC); simultaneous outputs possible. (For 100-240 V models)
VBS composite (576/50I: PAL), Y/C (576/50I: PAL), and RGB (576/50I: PAL); simultaneous outputs possible. (For 220-240 V models)
 Digital signal outputSDI (HD-SDI or SD-SDI), DV (IEEE1394), DVI (WUXGA, 1080P or SXGA) can be selected.
 White balance adjustmentWhite balance adjustment is possible using the white balance button on the front panel.
 AFI color balance adjustmentAFI color balance adjustment is possible using the AFI color balance cap in the AFI observation.
 Standard color chart outputThe “Color bar” or the “50% white” screen can be displayed.
 Color tone adjustmentThe 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 amplified when the light is inadequate due to the distal end of the endoscope being too far from the object.
 ContrastThe 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 reductionNoise is corrected by image processing.
 IrisThe auto iris modes can be selected using the “iris mode” switch on the front panel.
• Auto: The brightness is adjusted based on the brightest part of the central part and the average brightness of the periphery part. • 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 settingFine 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 modesThe enhancement level can be selected from 3 levels (1, 2, and 3) using the image enhancement mode button on the front panel.
 Adaptive IHb color enhancementEnhances small differences in colors based on the IHb values in endoscopic images.
 Switching the adaptive IHb color enhancement modesThe adaptive IHb color enhancement level can be selected from 3 levels (1, 2, and 3) using the color enhancement mode button on the front panel.
 Displaying the Ihb chart screenThe IHb chart screen is displayed using the “IHb CHART” key on the keyboard. The IHb chart screen calculates the IHb value of each pixel in the endoscopic image
and displays the IHb values in the corresponding positions in an image by representing the values using simulated colors.
 Rainbow color correctionAvoid the color deviation caused by the time lag between RGB signals and ensure a stable, flicker-free image.
 Image size selectionThe size of the endoscopic image can be changed using the “IMAGE SIZE” key on the keyboard.
 FreezeAn endoscopic image is frozen using an endoscope or the “FREEZE” key on the keyboard.
 Pre-freezeThe image with the least rainbow color is selected from the images captured in the set time period before freeze operation and displayed.
 Optical-digital observationThe optical-digital observation can be performed when using the endoscope and light source compatible with each optical-digital observation mode.
• NBI observation: This observation mode uses the narrow band observation light. • AFI observation: This observation mode uses the blue light.
• IRI observation: This observation mode uses the infra-red light.
 Endoscope’s remote switches functionThe functions of the remote switches on the endoscope can be set in the user settings.
 Reset to defaultsThe following settings can be reset to their defaults using the reset button on the front panel.
• Color tone (except AFI and IRI) • Iris mode • Image enhancement mode • Color enhancement mode • Optical-digital observation • Image size • Contrast
