Introduction to Sony Effio-A, Effio-V ISP

Dated back to 2009, Sony launched its newest "Effio" series image signal processor for working with CCD image sensor, which can deliver 960H/700TVL HD resolution images. The "Effio" series image sensor includes "Effio-E", "Effio-S", "Effio-P", today the Sony launched another two advanced image signal processors "Effio-V" and "Effio-A".

Effio-V (CXD4141GG) and Effio-A (CXD4151GG) are both high image quality which can deliver over 700 tv line resolution images from statement of Sony product's webpage.  That means 750 tv line or even 800 tv line security cameras based on Effio ISP will be available in market in near future. 

Over 700TVL resolution

Just like the above picture shows, being work with 960H CCD, both image signal processors can capture over 700 TVL resolution images.  960H CCD image sensor from Sony including (ICX810AKA/ICX811AKA/ICX662AKA/ICX663AKA/ICX668AKA/ICX669AKA/ICX872AKA/ICX873AKA/ICX672AKA/ICX673AKA/ICX678AKA/ICX679AKA)

2D+3D noise reduction with anti-blur function

The current model Effio-S and Effio-P both supports 2D+3D digital noise reduction, new Effio-V and Effio-A models increased the anti-blur function, which allow security cameras capture images without motion blur. This technology works both for static and motion scene.

wide dynamic range (WDR)

Both models support wide dynamic range,double shutter method is adopted in the CCD image sensor for WDR. Compared with other Effio ISP, newest ISP with more wide range Auto Trace White(ATW),which enables camera can capture images with exact color reproduction. More over, the new Effio ISP is supporting defog, smart IR and high low illumination sensitivity features.

Sony Effio-V/A Application

• Support 760H，960H WDR CCD
• Annul ARM9 MCU in Effio-P/S but improved DSP and add new function : 1.Encryption technology 2.Lens Shading compensation 3.RS485 coaxial communication 4.Scene selection ‧Even without MCU ,develop tool can do some modification in OSD(ex : add company logo, character modify ,Index modify)
• Integrated Line Lock circuit in DSP to avoid CCD color rolling

In summary, analogue security camera will not stop at 700TVL resolution, with continuously development of CCD sensor and digital signal processor, 750TVL, 800TVL even more high resolution cameras will be available. IP cameras totally replace the analogue camera may stagnated.
