LM9628

LM9628 Color CMOS Image Sensor VGA 30 FPS Version 0.9 October 02 Preliminary 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 convertor, fixed pattern noise elimination circuits, a video gain and separate 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. Features Video or snapshot operations Programmable pixel clock, inter-frame and inter-line delays. Programmable partial or full frame integration Programmable gain and individual color gain adjustment Horizontal & vertical sub-sampling (2:1 & 4:2) Programmable digital video response curve Windowing External snapshot trigger & event synchronisation signals Auto black level compensation Flexible digital video read-out supporting programmable: - polarity for synchronisation and pixel clock signals - leading edge adjustment for horizontal synchronization Programmable v...
