Eyenix is a Korean based video signal processing solution provider, Eyenix specializes in developing, manufacturing, marketing HD-SDI and EX-SDI image signal processors. Eyenix chips feature image restoration, pattern recognition, image stabilization, motion detection, image scaling etc functions. Additionally, the recently launched high-performance Eyenix HD-ISP can integrate different video encoder engines to provide IP camera solution.


Eyenix EN771C is a high-performance image signal processor which supports 1.3MP to 2MP CMOS image sensors. This ISP offers wide dynamic range (WDR), 2D/3D ADNR (Adaptive digital noise reduction), ACE (Adaptive contrast enhancing) etc functions. This image signal processor can be used in HD-SDI, EXSDI and HD-CVI cameras that offering Max. 1080P video with 30fps frame speed or 1.3 megapixel video at 60fps. A Full HD 1080P HD-CVI camera adopts 1/2.8" SONY IMX322 + Eyenix EN771C hardware design.



EN773 is a digital camera processor for security camera. This newly developed signal processor can work with 1.3MP - 3MP CMOS image sensors (Aptina, Sony, Pananosic, OmniVision). Through working with different CMOS sensors, the EN773E can provide 1.3MP@60fps, 2MP@45fps, 3MP@30fps video processing capability. Additionally, the EN773E features double-shutter WDR, 3D/3D ADNR, D-WDR, defog, lens shading compensation, 16x digital zoom, flip/mirror, motion detection, privacy masking, gamma correct etc functions. A Full HD 1080P HD-TVI camera may adopt 1/2.8" Sony IMX322/IMX323/IMX222 + EN773E + TP2801 hardware design. TP2801 is the 1080P transmitter supporting 1080P30/25 and 720P60/50.

EN773e HD-TVI Cameras


Eyenix EN773V is dedicated to provide Full HD 1080p HD video processing for HD-SDI and EX-SDI security cameras. EN773V advanced RGB interpolator for working with 1.3MP - 2MP high resolution CMOS image sensors. It is able to offer 1.3MP@30fps or 2MP@30fps video processing capability. Furthermore, this model supports WDR, 2D+3D ADNR, ACE, LSC, 8x Digital Zoom, Sense-up, privacy mask, motion detection, defog etc functions. A 2MP HD-SDI camera may utilize 1/3-inch Panasonic MN34227PL CMOS sensor + EN773V hardware design. A EX-SDI camera may utilize 1/3-inch Panasonic MN34229PL CMOS sensor (WDR sensor) + EN773V hardware design. Compared with HD-SDI, the EX-SDI offers maximum 450m long video transmission through the coaxial cable.

ACE (Adaptive Contrast Enhancing)

Adaptive Contrast Enhancer is necessary because imaging devices has narrow dynamic range. Conventional methods, such as Gamma Correction or Histogram Equalization, are normally lost their contents information in limit area, and then picture quality of bright/dark area can be degraded. Eyenix’s ACE processing is based on the human visual system. The ACE automatically calculates a different curve transformation for each pixel in image, based on an analysis of the image segmentation. Processed result image is capable of drastic adaptive contrast enhancer, while preserving fine details and avoiding common artifacts, gradient reversals or loss of local contrast.

3D ADNR (Adaptive Digital Noise Reduction)

The A-DNR is motion-compensated temporal noise reduction filter leads to effective noise reduction for motion video without blurring. The algorithms are based on accurately measurement of the local motion in a given video sequence, and local time averaging based on the degree and direction of motion. This spatiotemporal de-noising can reduce flickers in intraframe as well as random noise in time.
