LM9647 Color CMOS Image Sensor VGA 68 FPS
General Description
T h e LM9647 is a high performance, low power, 1/4" VGA CMOS A c t i v e 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 performance 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 a u t o m a t i c a l l y adjusted on chip using a full loop black level compensation circuit. Furthermore, a programmable smart timing and control circuit a l l o w i n g the user maximum flexibility in adjusting integration t i m e , active window size, gain, frame rate. Various control, timi n g and power modes are also provided.
