Pixel Array Description
Pixel Color Pattern Detail (Top Right Corner)
The MT9T031 pixel array is configured as 2,112 columns by 1,568 rows, as shown in
Figure 4. Columns from 0 through 27 and from 2,085 through 2,111 are optically black.
Similarly, rows from 0 through 15 and from 1,561 through 1,567 are optically black.
These optical black columns and rows can be used to monitor the black level. The black
row data is used internally for the automatic black level adjustment. However, the black
rows and columns can also be read out by setting R0x20 (11) and R0x1E (7), respectively.
There are 2,057 columns by 1,545 rows of optically active pixels, which provides a four-
pixel boundary around the QXGA (2,048 x 1,536) image to avoid boundary effects during
color interpolation and correction.
The MT9T031 uses a Bayer color pattern, as shown in Figure 5. The even-numbered rows
contain green and red color pixels, and odd-numbered rows contain blue and green
color pixels. The even-numbered columns contain green and blue color pixels; odd-
numbered columns contain red and green color pixels.
