MT9V112
SOC VGA DIGITAL IMAGE SENSOR
To assist in integration and system debug, a variety
of test patterns are provided, from simple ramps to
colorbars.
Contexts, Snapshots, and Flash
For a number of parameters, registers are provided
for storing two “contexts”: context A and context B.
These contexts enable the user to setup the camera for
a number of different modes, then switch between
modes with a single register WRITE to the global con-
text control register (GCCR). A typical example is to use
context A for viewfinder/preview settings and context
B for snapshots. Functions supporting context switch-
ing include:
• The resizer (output resolutions for preview and
snapshot)
• Camera interface (e.g., RGB565 for LCD preview and
YCbCr for snapshots)
To facilitate taking snapshots and flash snapshots,
the IFP includes a camera control sequencer that auto-
mates the process of stepping through a number of
preset configurable programs. In addition to basic
snapshots, there are programs for both Xenon and
LED assisted snapshots. A flash-triggering controller
provides an appropriate timing strobe for synchroniz-
ing the onset of flash illumination with the rolling
shutter.
