CXD3172AR

CXD3172AR Signal Processor LSI for Single CCD Color Camera Description The CXD3172AR 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 functions such as AE/AWB without an external microcomputer. Features Generates timing pulses to drive the single CCD image sensor Built-in H/V driver for CCD image sensor Luminance/chroma signal processing Supports NTSC/PAL modes Supports 510H/760H system CCD image sensor Built-in 10-bit A/D converter Built-in EVR (3ch) Analog composite output — Built-in digital encoder — 10-bit D/A converter output Digital output — Conforms to ITU-REC656/ITU-REC601 format Supports external sync functions — Sync separation circuit — Phase comparator AE/AWB detector Block control functions with a built-in microcontroller — AE/AWB/CLAMP/Blemish detection and compensation Peripheral IC control function — EVR/EEPROM communication control Serial communication function (2 mode selection) — Microcomputer communication/start-stop synchronous system communication (RS232C) Auto blemish detection and compensation function Mirror function Applications Industrial CCD cameras (Surveillance/FA/image input cameras) Multimedia CCD cameras (Teleconferencing/personal computer cameras) 100 pin ...
