Pixel Array Structure
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 V GA
(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.
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.

sive scan. Valid image data is surrounded by horizon-
tal and vertical blanking, as shown in Figure 6. The
amount of horizontal and vertical blanking is pro-
grammable through Reg0x05 and Reg0x06, respec-
tively. LINE_V A LID is HIGH during the shaded region
of the figure. See “Output Data Timing” on page 9 for
the description of FRAME_V A LID timing.
