General Description (Replace LC822973-04V1-TBM-GBE / LC822973-04V-TBM-GBE )

SR1913 is the smallest size 3.6mm x7mm BGA video encoder with frame rate buffer.

It is an advanced hardware-based  image processor designed to provide programmable wide 

angle lens distortion compensation and  keystone compensation.

This device accepts  digital video input ports for 10-bit interlaced or progressives.   

Output for  digital and analog CVBS video output with 10-bit progressive or interlace scan video 

with frame rate conversion.


SIZE:3.6mm x 7mm

Advanced frame rate control technology


Whatever CMOS sensor output is, SR1913 will smoothly convert progressive signal to CVBS.

You can configure your CMOS sensor that is at low frame rate  in low lux environment 

 At low lux environment, the exposure will rise












Mega pixel  YUV 422 Progressive input source and CVBS output

The video  source is more than VGA.

It will have enough video information to do the ePTZ and Keystone.

Keystone:









Camera module IC  diagram



Case 1: AUTO BOOT ( TO save your eBOM and PCB dimension)

This is simple mode that is digital CMOS to CVBS without any special function





Case 2: MCU Mode

If you need fisheye correction, keystone, ePTZ.......





Case 3: MCU + AUTO BOOT

If you want to powerful function and need extra control.....





 
Application


Endoscope / snake camera  / spy camera








Door Phone camera  with ePTZ  (digital zoom / ROI )












Car rear view  camera

請問BT656或CVBS輸出可以有960H的格式?

FEBON 提到...

沒有

只有一般的720H 的CVBS

但是如果你走百萬數位的話,
可以有 百萬的656 輸出
