Image Flow Processor Block Diagram
The MT9V131 features smooth, continuous zoom and pan. This functionality is avail-
able when the IFP output is downsized in the decimation block. The decimation block
can downsize the original VGA image to any integer size, including QVGA, QQVGA, CIF,
and QCIF with no loss to the field of view. The user can program the desired size of the
output image in terms of horizontal and vertical pixel count. In addition, the user can
program the size of a region for downsizing. Continuous zoom is achieved every time
the region of interest is less than the entire VGA image. The maximum zoom factor is
equal to the ratio of VGA to the size of the region of interest. For example, an image
rendered on a 160 x 120 display can be zoomed by 640/160 = 480/120 = 4 times. Contin-
uous pan is achieved by adjusting the starting coordinates of the region of interest.
Also, a fixed 2X up-zoom is implemented by means of windowing down the sensor core.
In this mode, the IFP receives a QVGA-sized input data and outputs a VGA-size image.
The sub-window can be panned both vertically and horizontally by programming
sensor core registers.
The MT9V131 supports both LED and Xenon-type flash light sources using a dedicated
output pad. For Xenon devices, the pad generates a strobe to fire when the imager's
shutter is fully open. For LED, the pad can be asserted or de-asserted asynchronously.
Flash modes are configured and engaged over the two-wire serial interface using IFP .
