The on-chip auto exposure allows for a wide range of lighting
conditions, eliminating the need for external mechanical shutter components. This, along with its single supply, low power
consumption makes the OV5116P an incredibly versatile and
cost-effective video camera perfect for the following types of

I-Ø
A logic level input to enable/disable AGC/AEC FAST mode. High enables, low disables,
which provides slow and smooth AGC/AEC mode.
16
BPED
I-Ø
A logic level input to disable on chip edge enhancement. High disable, low enable.

A logic level pin to select the transfer characteristic of output voltage versus light input.
Logic high for g=0.45; low for g=1.

FSO/MIRR
I/O
In/out pin.Frame Sync Output. Digital frame sync output pin. Positive pulse occurs during
the CVO vertical sync period. Input is a logic level input to enable mirror function.

and in sync with PCLK. Input is a logic level input to enable maximum AGC gain to 8x
(only effective when pin 14 is set to high(1))
The composite video output signal. The output is a source follower capable of directly
driving a 1V p-p signal into a 108 Ω load.(75Ω external and 33Ω internal)

Note: Most lens assemblies reverse the viewed scene onto the sensor array,
which generally means that pin 1 should be located at the bottom of the p.c. board.
To ensure correct display orientation, check the lens specification prior to
laying out the printed circuit board.
