Horizontal mirror and vertical flip

The image data output from the VL6524/VS6524 can be mirrored horizontally or flipped

vertically (or both).

These functions are available in the

Pipe setup bank0 control register bank.

ViewLive Operation

ViewLive is an option which allows different size, format and image settings to be applied to

alternate frames of the output data.

The controls for ViewLive function are found in the

View live control register bank where the

fEnable register allows the host to enable or disable the function and the

InitalPipeSetupBank register selects which pipe setup bank is output first (see Table 18:

View live control for register description).

Video pipe setup

The key controls for VL6524/VS6524 video pipe setup are grouped into register banks

called

Pipe setup bank0 control and Pipe setup bank1 control.

Pipe setup bank0 control setup is used when ViewLive is disabled.

When ViewLive is enabled the output data switches between

Pipe setup bank0 control and

Pipe setup bank1 control on each alternate frame.
