Block Diagram
The MT9V022 active imaging pixel array is 752H x 480V. It incorporates sophisticated
camera functions on-chip, such as averaging 2 x 2 and 4 x 4, to improve SNR when oper-
ating in smaller resolutions, as well as windowing and column and row mirroring. It is
programmable through a simple two-wire serial interface. The MT9V022 pixel response
can be configured for either linear light response with >55dB of dynamic range or for
high dynamic range response with as much as 100dB of dynamic range.
The MT9V022 can be operated in its default mode or be programmed by the user for
frame size, exposure, gain setting, and other parameters. The default mode outputs a
wide-VGA-sized image at 60 frames per second (fps). An on-chip analog-to-digital con-
verter (ADC) provides 10 bits per pixel. The user can alternatively enable 12-bit resolu-
tion companded to 10 bits for small signals, enabling more accurate digitization for
darker areas in the image.
In addition to a traditional, parallel logic output, the MT9V022 also features a serial low-
voltage differential signaling (LVDS) output.
The sensor can be operated in stereo-camera mode, where 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 (–40°C to +85°C). A built-
in digital thermometer allows the host to read the temperature through the two-wire
serial interface.
The MT9V022 works in master, snapshot, or slave mode. In master mode, the sensor
generates the readout timing. There are two possible operation methods for master
mode: simultaneous and sequential. In simultaneous master mode, the exposure period
occurs during readout. The exposure and readout occur in parallel rather than sequen-
tially, making this the fastest mode of operation.
In sequential master mode, the exposure period is followed by readout, and the frame
rate changes as the integration time changes.
In snapshot mode, the start of the integration period is determined by the externally-
applied EXPOSURE pulse that the user inputs to the MT9V022. The sensor in snapshot
mode can capture a single image or a sequence of images.
