LM9618 Monochrome CMOS Image Sensor VGA 30 FPS
General Description
T h e LM9618 is a high performance, low power, 1/3" VGA CMOS Active Pixel Sensor capable of capturing grey-scale 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 convertor, fixed pattern noise elimination circuits, a video gain and separate color gain are provided. Furthermore, an integrated p r o g r a m m a b l e smart timing and control circuit allows the user m a x i m u m 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 e x t e n d e d to above 100dB by programming a non linear r e s p o n s e curve that matches the response of the human eye.
