BU6520KV_10 Datasheet, PDF (1/19 Pages) Rohm – Video Encoders built-in Image Correction

AIE Adaptive Image Enhancer Series
Video Encoders
built-in Image Correction
BU6520KV,BU6521KV
No.10060ECT03
●Description
BU6520KV, BU6521KV are video encoders with built-in AIE image correcting function. Also, BU6521KV has the image
correcting function of the fog reduction, too.
Fog Reduction, the brightness correction, the backlight correction and the chroma emphasis can improve the visibility of the
input image of the camera.
* AIE and Fog Reduction function are image processing technology by ROHM’s hardware.
●Features
1) Format of video output is compatible with NTSC/PAL composite video format (CVBS).
Built-in DAC with direct 75Ω drive capability.
2) Built-in Fog Reduction function^*1, dynamic range correction, edge-emphasizing filter and gamma filter.
3) Input/output data format is compatible with ITU-R BT.656 and YCbCr=4:2:2 with synchronization signal.
4) Compatible with NTSC (27MHz, 28.63636MHz and 19.06993MHz)/
PAL(27MHz, 28.375MHz, 35.46895MHz and 18.9375MHz) ^*2.
5) Registers can be set up with a 2-line serial interface.
6) Registers can be automatically set up by reading from external EEPROM, when after resetting or changing mode.
*1 As for the Fog Reduction feature, it loads only BU6521KV.
*2 NTSC 19,06993 MHz and PAL 18,9375 MHz support only BU6521KV.
