CXD4141 Datasheet – System ICs for Security Camera

Overview

System ICs for High Resolution and High Sensitivity Cameras Support 960H CCD Image Sensors Sony has developed system ICs for analog security cameras, the Effio-V (CXD4141GG) and Effio-A (CXD4151GG) with drastically improved functions and performance as the third generation of the EffioTM series. The Effio-V and Effio-A can be combined with 960H CCD image sensors to realize the highest horizontal resolution over 700 TV lines in the Effio series. Also, the ICs improved overall functions such as noise reduction (3D-NR), exposure optimization of infrared LED, wide dynamic range (WDR), or defog. And visibilities in different conditions with low light, infrared light, or high (low) contrast were greatly improved.

The CXD4103R is a signal processor LSI for Ye, Cy, Mg, and G single CCD color cameras. In addition to basic camera signal processing functions, it includes an AE/AWB detection circuit, a sync signal generation circuit, and an external sync circuit, etc. This chip also has a built-in microcontroller to realize basic camera control functions such as AE/AWB without an external microcomputer.
