Frame control

Sensor mode control

The VS6624 device can operate it’s sensor array in three modes controlled by register

SensorMode within

Mode setup.

●

SensorMode_SXGA - the full array is readout and the max frame rate achievable is

15fps

●

SensorMode_VGA_analogue binning - the full array operates and a technique of

analogue binning is used to output VGA at up to 30fps

●

SensorMode_VGA_subsampled - the array is sub-sampled to output VGA at up to

30fps

Image size

An output frame consists of a number of active lines and a number of interframe lines. Each

line consists of embedded line codes (if selected), active pixel data and interline blank data.

Note that by default the interline blanking data is

not qualified by the PCLK and therefore is

not captured by the host system.

The image size can be either the full output from the sensor, depending on sensor mode, or

a scaled output, The output image size can be chosen from one of 7 pre-selected sizes or a

manual image size can be input.

Cropping module

The VS6624 contains a cropping module which can be used to define a window of interest

within the full SXGA array size. The user can set a start location and the required output

size.

Figure 4 shows the example with pipe setup bank0.
