LM9647 Color CMOS Image Sensor VGA 68 FPS
General Description
The LM9647 is a high performance, low power, 1/4" VGA CMOS
Active Pixel Sensor capable of capturing color still or motion
images and converting them to a digital data stream.
Excellent image quality is achieved by integrating a high perfor-
mance analog signal processor comprising of a high speed 10
bit A/D convertor, fixed pattern noise elimination circuits and
separate color gain amplifiers . The offset and black level can be
automatically adjusted on chip using a full loop black level com-
pensation circuit.
Furthermore, a programmable smart timing and control circuit
allowing the user maximum flexibility in adjusting integration
time, active window size, gain, frame rate. Various control, tim-
ing and power modes are also provided.
Features
f Master and slave mode operation
f Progressive scan read out with horizontal and vertical flip
f Programmable Exposure:
f Four channels of digitally programmable analog gain
f Full automatic servo loop for black level & offset adjustment
f Horizontal & vertical sub-sampling (2:1 & 4:2) with averaging
f Windowing
f Programmable pixel clock, inter-frame and inter-line delays
f I
f Power on reset & power down mode
