MT9D111 - 1/3.2-Inch 2-Megapixel SOC Digital Image Sensor
Sensor Core
Micron Confidential and Proprietary
Default Readout Order
By convention, the sensor core pixel array is shown with pixel (0,0) in the top right-hand
corner (see Figure 15). This reflects the actual layout of the array on the die. When the
sensor is imaging, the active surface of the sensor faces the scene as shown in Figure 16.
When the image is read out of the sensor, it is read one row at a time, with the rows and
columns sequenced as shown in Figure 14. By convention, data from the sensor is shown
with the first pixel read out—pixel (52,20) in the case of the sensor core—in the top left-
hand corner.
Figure 16: Imaging a Scene
Raw Data Format
The sensor core image data is read out in a progressive scan. Valid image data is sur-
rounded by horizontal blanking and vertical blanking as shown in Figure 17. The
amount of horizontal blanking and vertical blanking is programmable. LINE_VALID is
HIGH during the shaded region of the figure. FRAME_VALID timing is described in the
next section.
