Digital Gain Tiled Sample
The integrated AEC/AGC unit is responsible for ensuring that optimal auto settings of
exposure and (analog) gain are computed and updated every frame.
When the AGC or AEC are enabled, the MT9V022 measures current scene luminosity
and desired output luminosity by accumulating a histogram of pixel values while read-
ing out a frame. The desired exposure and gain are then calculated and applied for the
subsequent frame.
The pixel clock speed is same as the master clock of 26.66 MHz by default. However,
when column binning 2 or 4 is enabled, the pixel clock speed will be reduced by half or
one-fourth of the master clock speed, respectively.
The analog gain range supported in the MT9V022 is 1X–4X with a step size of 6.25
percent.
In the MT9V022, the user either may apply a single gain value for the entire array or they
may divide the image into 25 tiles (Figure 9) through the two-wire serial interface and
apply digital gain individually to each tile.
The coordinates and digital gain (0.25 - 3.75X) of each tile may be individually pro-
grammed via the two-wire serial interface. This feature should help improve pulling
detail out of regions of an image that are either dark, or lighter than the rest of the scene
without affecting the rest of the scene.
To ease mounting orientation issues, the MT9V022 column and row readout order can
be independently reversed via the two-wire serial interface. The image will then be rep-
resented correctly regardless of camera orientation.
