The MT9V131 can accept the input clock of up to 27 MHz, delivering 30 fps. With
power-on defaults, the camera is configured to deliver 15 fps at 12 MHz and automati-
cally slows down the frame rate in low-light conditions to achieve longer exposures and
better image quality.
Internally, the MT9V131 consists of a sensor core and an image flow processor. The
sensor core functions to capture raw Bayer-encoded images that are input into the IFP
as shown in Figure 2. The IFP processes the incoming stream to create interpolated,
color-corrected output and controls the sensor core to maintain the desirable exposure
and color balance.
