Preliminary
MT9D131: 1/3.2-Inch 2-Mp SOC Digital Image Sensor
Architecture Overview
Output Interface
Control (Two-Wire Serial Interface)
Camera control and JPEG configuration/control are accomplished using a two-wire
serial interface. The interface supports individual access to all camera function registers
and JPEG control registers. In particular, all tables located in the JPEG quantization and
Huffman memories are accessible using the two-wire interface.
Context and Operational Modes
The MT9D131 can operate in several modes, including preview, still capture (snapshot),
and video. All modes of operation are individually configurable and are organized as two
contexts—context A and context B. A context is defined by sensor image size, frame rate,
resolution and other associated parameters. The user can switch between the two con-
texts by sending a command through the two-wire serial interface.
Preview
Context A is primarily intended for use in the preview mode. During preview, the sensor
usually outputs low resolution images at a relatively high frame rate, and its power con-
sumption is kept to a minimum. Context B can be configured for the still capture or
video mode, as required by the user. For still capture configuration, the user typically
specifies the desired output image size, if JPEG compression, how many frames to cap-
ture, and so on. For video, the user might select a different image size and a fixed frame
rate.
Snapshot
To take a snapshot, the user must send a command that changes the context from A to
context B. Typical sequence of events after this command is as follows. First, the camera
exposure and white balance is automatically adjusted to the changed illumination of the
scene. Next, the camera enables JPEG compression and capture one or more frames of
desired size. Completing the sequence, the camera automatically returns to context A
and resume running preview.
Video
To start video capture, the user has to change relevant context B settings, such as cap-
ture mode, image size and frame rate, and again send a context change command. Upon
receiving it, the MT9D131 switches to the modified context B settings, while continuing
to output YUV-encoded image data. Auto exposure automatically switches to smooth
continuous operation. To exit the video capture mode, the user has to send another con-
text change command causing the sensor to switch back to context A.
