ADVANCE INFORMATION
LM9628 Color CMOS Image Sensor VGA 30 FPS
General Description
The LM9628 is a high performance, low power, 1/3" VGA CMOS
Active Pixel Sensor capable of capturing color digital still or
motion images and converting them to a digital data stream.
In addition to the active pixel array, an on-chip 12 bit A/D conver-
tor, fixed pattern noise elimination circuits, a video gain and sep-
arate color gain amplifier are provided. Furthermore, an
integrated programmable smart timing and control circuit allows
the user maximum flexibility in adjusting integration time, active
window size, gain and frame rate. Various control, timing and
power modes are also provided.
The excellent linear dynamic range of the sensor can be
extended to above 100dB by programming a non linear
response curve that matches the response of the human eye.
