The MT9V135 is a fully-automatic, single-chip camera, requiring only a single power
supply, lens, and clock source for basic operation. Output video is streamed via the
chosen output port. The MT9V135 internal registers are configured using a two-wire
serial interface.
The device can be put into a low-power sleep mode by asserting STANDBY and shutting
down the clock. Output signals can be tri-stated. Both tri-stating output signals and
entry into standby mode can be achieved via two-wire serial interface register writes.
The MT9V135 requires an input clock of 27 MHz to support correct NTSC or PAL timing.
Internally, the MT9V135 consists of a sensor core and an image flow processor (IFP). The
IFP is divided in two sections: the colorpipe, and the camera controller. The sensor core
captures raw images that are then input into the IFP. The colorpipe section processes the
incoming stream to create interpolated, color-corrected output, and the camera
controller section controls the sensor core to maintain the desired exposure and color
balance.
The IFP scales the image and an integrated video encoder generates either NTSC or PAL
analog composite output. The MT9V135 supports three different output ports; analog
composite video out, LVDS serial out and CCIR 656 interlaced digital video in parallel 8-
bit format.
Figure 2 shows the major functional blocks of the MT9V135. The built-in NTSC/PAL
encoder and the LVDS Formatter allow simultaneous outputs of composite and digital
video signals. This is especially useful during installation of network cameras and allows
the installer to adjust the camera view and focus using analog monitoring equipment
while the digital viedo is compressed and formatted for IP network delivery.
