The Micron® Imaging MT9V403 VGA-based CMOS active-pixel sensor has a 1/2-inch optical format and delivers superb resolution at a turbocharged 200 fps, making it the perfect solution for machine vision assembly lines, airbag deployment, golf swing analysis, and special effects in movies.

The freeze-frame shutter MT9V403 allows the signal charges of all pixels to be integrated in parallel-all pixels start integrating simultaneously and stop integrating simultaneously. The charges of MT9V403 are then sampled into pixel analog memories (one memory per pixel) and consequently, row by row, are digitized and read out-of-chip.

The sensor MT9V403 works in master, snapshot, or slave mode. In master mode it generates the readout timing on-chip. In snapshot mode it accepts an external trigger and then generates the readout timing. In slave mode the sensor accepts external readout timing. The integration time is programmed through the two-wire serial interface (master or snapshot mode) or controlled via externallygenerated control signals (slave mode). The scanning mode of MT9V403 can be progressive or interlaced. There is also an option to scan just a window of interest by choosing start row and column and stop row and column. The user can control the frame rate and row rate through the use of vertical and horizontal blanking as well as the master clock frequency.

The readout of the data out of the chip can be done simultaneously with integration and ADC operation due to the two-cell SRAM which allows data from the previously converted row to be shifted into the output memory for readout. The sensor MT9V403's ADCs contain special self-calibrating circuitry that allow the sensor to reduce its own column- wise fixed pattern noise. The calibration coefficients can be read from, and written to, the sensor.
