Block Diagram
The MT9V034 is a 1/3-inch wide-VGA format CMOS active-pixel digital image sensor
with TrueSNAP™ global shutter and high dynamic range (HDR) operation. The sensor
has specifically been designed to support the demanding interior and exterior surveil-
lance imaging needs, which makes this part ideal for a wide variety of imaging applica-
tions in real-world environments.
This wide-VGA CMOS image sensor features DigitalClarity
low-noise CMOS imaging technology that achieves CCD image quality (based on
signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost,
and integration advantages of CMOS.
The active imaging pixel array is 752H x 480V. It incorporates sophisticated camera func-
tions on-chip—such as binning 2 x 2 and 4 x 4, to improve sensitivity when operating in
smaller resolutions—as well as windowing, column and row mirroring. It is program-
mable through a simple two-wire serial interface.
The MT9V034 can be operated in its default mode or be programmed for frame size,
exposure, gain setting, and other parameters. The default mode outputs a
wide-VGA-size image at 60 frames per second (fps).
An on-chip analog-to-digital converter (ADC) provides 10 bits per pixel. A 12-bit resolu-
tion companded for 10 bits for small signals can be alternatively enabled, allowing more
accurate digitization for darker areas in the image.
In addition to a traditional, parallel logic output the MT9V034 also features a serial low-
voltage differential signaling (LVDS) output. The sensor can be operated in a stereo-
camera, and the sensor, designated as a stereo-master, is able to merge the data from
itself and the stereo-slave sensor into one serial LVDS stream.
The sensor is designed to operate in a wide temperature range (–30°C to +70°C).
