MT9D111 - 1/3.2-Inch 2-Megapixel SOC Digital Image Sensor
Sensor Core
Micron Confidential and Proprietary
Pixel Array Structure
The sensor core pixel array is configured as 1,688 columns by 1,256 rows (shown in
Figure 14). The first 52 columns and the first and the last 20 rows of pixels are optically
black and are used for the automatic black level adjustment. The last 4 columns are also
optically black.
The optically active pixels are used as follows: In default mode a UXGA image (1,600 col-
umns by 1,200 rows) is generated, starting at row 28, column 60. A 4-pixel boundary of
active pixels can be enabled around the image to avoid boundary effects during color
interpolation and correction. During mirrored readout, the region of active pixels used
to generate the image is offset by 1 pixel in each mirrored direction so that the readout
always starts on the same color pixel.
Figure 14: Pixel Array
The sensor core uses a Bayer color pattern, as shown in Figure 15. The even-numbered
rows contain green and red color pixels; odd-numbered rows contain blue and green
color pixels. Even-numbered columns contain green and blue color pixels; odd-num-
bered columns contain red and green color pixels. The color order is preserved during
mirrored readout.
