Rolling Shutter Mode
The sensor also supports the rolling shutter mode. The
shutter mechanism is an electronic rolling shutter and the
sensor operates in streaming mode similar to a video. This
mechanism is controlled by the on-chip sequencer logic.
There are two Y pointers, as indicated in Figure 11. One of
them points to the row that is to be reset for rolling shutter
operation and the other points to the row to be read out.
Functionally, a row is reset first and selected for readout
later. The time elapsed between these two operations is the
exposure time.
Figure 11 schematically indicates the relative shift of the
integration times of different lines during rolling shutter
operation. Each row is read and reset sequentially, as
described in the previous paragraph. Each row in a particular
frame is integrated for the same time, but all lines in a frame
‘see’ a different stare time. Therefore, fast horizontal
moving objects in the field of view give rise to motion
artifacts in the image; this is an unavoidable property of a
rolling shutter.
In rolling shutter mode, a second pointer indicates the
rows that need to be reset for the rolling shutter mechanism.
The distance between the reset pointer and the readout
pointer determines the integration time.
The VITA 25K supports dynamic exposure time updates
without artifacts or interrupting the image data stream.
