The OV9650 sensor has an active image array of 1300
columns by 1028 rows (1,336,400 pixels).
a cross-section of the image sensor array.
In general, the timing generator controls the following
functions:
•
•
•
•
•
This block performs all analog image functions including:
•
•
After the Analog Processing block, the bayer pattern Raw
signal is fed to two 10-bit analog-to-digital (A/D)
converters via two multiplexers, one for the G channel and
one shared by the BR channels. These A/D converters
operate at speeds up to 12 MHz and are fully synchronous
to the pixel rate (actual conversion rate is related to the
frame rate).
Array control and frame generation (7 different
format outputs)
Internal timing signal generation and distribution
Frame rate timing
Automatic Exposure Control (AEC)
External timing outputs (VSYNC, HREF/HSYNC, and
PCLK)
Automatic Gain Control (AGC)
Automatic White Balance (AWB)

In addition to the A/D conversion, this block also has the
following functions:
•
•
•
In general, the combination of the A/D Range Multiplier
and A/D Range Control sets the A/D range and maximum
value to allow the user to adjust the final image brightness
as a function of the individual application.
This block controls the interpolation from Raw data to
RGB and some image quality control.

This block controls all output and data formatting required
prior to sending the image out.
