OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, announced from MD&M East in NYC the OV2741, a new PureCel-S stacked-die sensor that extends OmniVision’s high definition (HD) medical image sensor family. The OV2741 provides 1080p full HD resolution and high image quality in a compact chip-scale package. It offers 1920 x 1080 resolution at a rate of 60 frames per second (FPS), for jitter-free, full-HD video. It also has a broadband double anti-reflective coating on its cover glass to eliminate glare, ghosting and reflections due to strong illumination.

With high image quality, ease of integration, and compact size, the OV2741 is ideal for many endoscopic devices used in diagnostic and surgical procedures, including airway-management (esophagoscopes, laryngoscopes, thorascopes, pleuroscopes, bronchoscopes, mediastinoscopes) and gastro-intestinal (gastroscopes, duodenoscopes, amniscopes) applications.

“To ensure the best patient outcomes, surgeons need 1080p HD resolution and excellent image quality when performing endoscopic surgeries,” said Tehzeeb Gunja, principal marketing and business development manager at OmniVision. “The OV2741 meets those needs, while eliminating the glare and reflections from endoscope lights by using an innovative anti-reflective coating.”

The OV2741 image sensor has a 1/6-inch optical format for excellent low-light operation, a 1.4-micron pixel size and supports RAW data output. The sensor’s PureCel-S stacked pixel architecture delivers the highest-quality images with improved sensitivity, less saturation, high full-well capacity, no blooming and low color crosstalk.

The OV2741’s low power consumption of just 90 mW, while operating at 60 FPS and full HD resolution, keeps the distal tip of the endoscope cooler for greater patient comfort. The OV2741 is also stereo-ready, enabling two image sensors to be synchronized for 3D video during surgical procedures.

The sensor integrates one-time-programmable (OTP) memory to store manufacturing and calibration information. It also has an on-chip pulse width modulator (PWM) to drive LED illumination without the need for an external driver IC. Additionally, the OV2741 can be both autoclaved for reusable applications and sterilized for disposable ones.

OmniVision Technologies is a leading developer of advanced digital imaging solutions. Its award winning CMOS imaging technology enables superior image quality in many of today’s consumer and commercial applications, including mobile phones, notebooks, tablets and webcams, digital still and video cameras, security and surveillance, entertainment devices, automotive and medical imaging systems.
