MT9V131: 1/4-Inch SOC VGA CMOS Digital Image Sensor
General Description
General Description
This SOC VGA CMOS image sensor features ON Semiconductor’s breakthrough, low-
noise CMOS imaging technology that achieves CCD image quality (based on signal-to-
noise ratio and low-light sensitivity) while maintaining the inherent size, cost, and inte-
gration advantages of CMOS.
The MT9V131 is a fully-automatic, single-chip camera, requiring only a power supply,
lens, and clock source for basic operation. Output video is streamed through a parallel 8-
bit DOUT port, as shown in Figure 1. The output pixel clock is used to latch the data,
while FRAME_VALID (FV) and LINE_VALID (LV) signals indicate the active video. The
sensor can be put in an ultra-low power sleep mode by asserting the STANDBY pin.
Output signals can also be tri-stated by de-asserting the OE_BAR pin. The MT9V131
internal registers can be configured using a two-wire serial interface.
The MT9V131 can be programmed to output progressive scan images up to 30 fps in an
8-bit ITU_R BT.656 (YCbCr) formerly CCIR656, YUV, 565RGB, 555RGB, or 444RGB
formats. 10-bit raw Bayer data output can also be selected. The FV and LV signals are
output on dedicated pins, along with a pixel clock (PIXCLK) that is synchronous with
valid data.

The MT9V131 can accept an input clock of up to 27 MHz, delivering 30 fps. With
power-on defaults (see Appendix B on page 28 for recommended defaults), the camera is
configured to deliver 15 fps at 12 MHz and automatically 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 (IFP). The
sensor core functions to capture raw Bayer-encoded images that are input into the IFP
as shown in Figure 1. 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.
Sensor core and IFP registers are grouped into two separate address spaces, as shown in
Figure 2 on page 7. The internal registers can be accessed through the two-wire serial
interface. Selecting the desired address space can be accomplished by programming
register R0x01, which remains present in both register sets.
