General Description
The ON SemiconductorMT9V111 is a 1/4-inch VGA-for-
mat 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 MT9V111 has an active imag-
ing 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 battery-powered products such
as cellular phones, PDAs, and toys. It incorporates
sophisticated camera functions on-chip and is pro-
grammable through a simple two-wire serial interface.

OUTPUT FORMATTING
The MT9V111 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 160x120 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 MT9V111 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
Reg0x98.
