Snapshot (Synchronous) Shutter
A synchronous (global, snapshot) shutter solves the inconve-
nience found in the rolling shutter. Light integration takes place
on all pixels in parallel, although subsequent readout is
sequential.

synchronous shutter. All pixels are light sensitive at the same
period of time. The whole pixel core is reset simultaneously
and after the integration time all pixel values are sampled
together on the storage node inside each pixel. The pixel core
is read out line by line after integration. Note that the
integration and read out cycle is carry-out in serial, which
causes that no integration is possible during read out.
During synchronous shutter the input pins SS_START and
SS_STOP are used to start and stop the synchronous shutter.

Most of these signals are generated on-chip by the sequencer
that uses only a few control signals. These control signals
should be generated by the external system:
The relative position of the pulses is determined by a number
of data bits that are uploaded in internal registers through the
serial or parallel interface.
Internal Registers

a short description. In the next section, the registers are
explained in more detail.
• SYS_CLOCK (X-clock), which defines the pixel rate
• Y_START pulse, which indicates the start of a new frame
• Y_CLOCK, which selects a new row and starts the row
• SS_START and SS_STOP to control the integration period
