YUV conversion
used to control the contrast and color saturation of the output image as well as the fade to
black feature.
Dither
images with truncated data.
Output formatter
the data stream to allow the host system to synchronize with the output data. It also controls
the optional HSYNC and VSYNC output signals.
Microprocessor functions
The microprocessor inside the VL6624/VS6624 performs the following tasks:
Host communication handles the I²C communication with the host processor.
Video pipe configuration configures the video pipe modules to produce the output
required by the host.
Automatic exposure control In normal operation the VL6624/VS6624 determines the
appropriate exposure settings for a particular scene and outputs correctly exposed images.
Flicker cancellation The 50/60Hz flicker frequency present in the lighting (due to
fluorescent lighting) can be cancelled by the system.
Automatic white balance The microprocessor adjusts the gains applied to the individual
color channels in order to achieve a correctly color balanced image.
Frame rate control
This automatically designs internal video timings, PLL multipliers, clock dividers etc. to
achieve a target frame rate with a given input clock frequency.
Optionally an automatic frame rate controller can be enabled. This system examines the
current exposure status, integration time and gain and adapts the frame rate based on that.
This function is typically useful in low-light scenarios where reducing the frame rate extends
the useful integration period. This reduces the need for the application of analog and digital
gain and results in better quality images.
Dark calibration
the pixel array to apply an offset to the video data and ensure a consistent ‘black’ level.
Active noise management The microprocessor is able to modify certain video pipe
functions according to the current exposure settings determined by the automatic exposure
controller. The main purpose of this is to improve the noise level in the system under low
lighting conditions. Functions which ‘strength’ is reduced under low lighting conditions (e.g.
sharpening) are controlled by ‘dampers’. Functions which ‘strength’ is increased under low
lighting conditions are controlled by ‘promoters’. The fade to black operation is also
controlled by the microprocessor
This module performs color space conversion from RGB to YUV. It is
