Pixel Data Format
Pixel Array Structure
The MT9V011’s pixel array is 668 columns by 496
rows. The first 18 columns and the first 6 rows of pixels
are optically black and can be used to monitor the
black level. The last column and the last row of pixels
are also optically black. The black row data is used
internally for automatic black level adjustment. There
are 649 columns by 489 rows of optically active pixels,
which provides a four-pixel boundary around the VGA
(640 x 480) image to avoid boundary affects during
color interpolation and correction. The additional
active column and additional active row are used to
allow horizontally and vertically mirrored readout to
also start on the same color pixel, as shown in Figure 4.
Figure 4: Pixel Array Description
The MT9V011 uses the RGB Bayer color pattern.
Even numbered rows contain green and red color pix-
els, and odd numbered rows contain blue and green
color pixels. Likewise, even numbered columns con-
tain green and blue color pixels, and odd numbered
columns contain red and green color pixels.

Output Data Format
The MT9V011 image data is read-out in a progres-
sive scan. Valid image data is surrounded by horizon-
tal and vertical blanking, as shown in Figure6. The
amount of horizontal and vertical blanking is pro-
grammable through Reg0x05 and Reg0x06, respec-
tively. LINE_VALID is HIGH during the shaded region
of the figure. See “Output Data Timing” on page 9 for
the description of FRAME_VALID timing.
