Automatic frame rate control
When enabled, the automatic frame rate control will reduce the frame rate in low light levels
to improve image quality. By default the minimum frame rate that the device will use is 5 fps.
Fade to black
Using programmable levels the microprocessor will fade the output signal to black. This
ensures that under the darkest conditions, when the image is not of sufficient quality, the
device will output black. This operation is achieved by scaling the RGB to the YCbCr matrix.
Audio data pipeline (ADP)
The audio block contains functions allowing the capture and processing of audio data from
an external microphone. The processed data is then written into an external FIFO which is
in turn read by the USB control.

System control overview
In the VL6522, the embedded microcontroller has five main functions:
●
●
●
●
The task of the exposure control is to ensure that all scenes are correctly exposed to provide
a good level of contrast. In normal operation the VL6522 will use hardware-generated
statistics to determine appropriate exposure settings for a particular scene and adjust the
system accordingly to give a correctly exposed image.
●
Using hardware-generated statistics the microcontroller adjusts the gains applied to the
individual color channels in order to achieve a correctly color balanced image.
