General Description
The ON Semiconductor MT9V131 is a 1/4-inch VGA-
format CMOS active-pixel digital image sensor, the
result of combining the MT9V011 image sensor core
with ON Semiconductor's third-generation digital
image flow processor technology. The MT9V131 has an
active imaging pixel array of 649 x 489, capturing high-
quality color images at VGA resolution.
The sensor is a complete camera-on-a-chip solution
and is designed specifically to meet the demands of
products such as surveillance cameras. It incorporates
sophisticated camera functions on-chip and is pro-
grammable through a simple two-wire serial interface.

OUTPUT FORMATTING
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. Continuous 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 signal generates a strobe to fire when the imager's
shutter is fully open. For LED, the signal can be asserted or de-asserted asynchronously.
Flash modes are configured and engaged over the two-wire serial interface using IFP
R0x98.
