VL6624/VS6624

Horizontal mirror and vertical flip

The image data output from the VL6624/VS6624 can be mirrored horizontally or flipped

vertically (or both).

Video pipe setup

The VS6624 has a single video pipe, the control of this pipe can be loaded from either of two

possible setups Pipesetupbank0 and Pipesetupbank1;

Pipe setup bank0 and Pipe setup bank1, control the operations shown below,

●

image size

●

zoom control

●

pan control

●

Crop control

●

Image format (YUV 4:2:2, RGB565, etc....)

●

Image controls (Contrast, Color saturation, Horizontal and vertical flip)

Pipe 0 RGB to YUV matrix manual control and Pipe 1 RGB to YUV matrix manual control,

allow different RGB to YUV matrixes to be used for each pipe setup,

Pipe 0 gamma manual control and Pipe 1 Gamma manual control, allow different gamma

settings to be used for each pipe setup.

Context switching

In normal operation, it is possible to control which pipe setup bank is used and to switch

between banks without the need to stop streaming, the change will occur at the next frame

boundary after the change to the register has been made.

For example this function allows the VL6624/VS6624 to stream an output targeting a display

(e.g. QQVGA RGB 444) then switch to capture an image (e.g. SXGA YUV 4:2:2) with no

need to stop streaming or enter any other operating mode.

It is important to note the output size selected for both pipe setups must be appropriate to

the sensor mode used, i.e. to configure PipeSetupBank0 to QQVGA and PipeSetupBank1

to SXGA the sensor mode must be set to SXGA.

The register

Mode setup allows selection of the pipe setup bank, by default the Pipe setup

bank 0 is used.
