The exposure of global shutter sensors starts for all pixel rows at the same time, see Shutter methods.

The rows are read out sequentially row by row. The read-out duration depends on various factors, such as:

sensor

pixel format

ROI (region of interest)

decimation and binning

The camera generates the following internal signals:

Signal

Description

ExposureActive

TRUE during exposure of the pixels.

ExposureStart

Indicates the start of exposure (= start of "ExposureActive").

ExposureEnd

Indicates the end of exposure (= end of "ExposureActive").

ReadOutActive

TRUE during the read-out of the pixels.

ReadOutStart

Indicates the start of the read-out (= start of "ReadOutActive").

ReadOutEnd

Indicates the end of the read-out (= end of "ReadOutActive").

Additionally, the camera generates the following events (see Activating events), informing a host application about their occurrence:

Event

Description

Event data

ExposureStart

Notify the host application about the start of exposure.

Corresponding frame ID

ExposureEnd

Notify the host application about the end of exposure.

Most global shutter sensors allow for overlapping frames. This means, that the exposure of the next frame can already be started, while the previous frame is still read out. In this case, the camera signals "ExposureActive" and "ReadOutActive" overlap, too.

The maximum overlap depends on the ratio of exposure time and read-out duration. The shorter of the two defines the maximum overlap.
