The LUPA4000 sensor operates in the global shutter mode.
Global Shutter Mode
all pixels in parallel, although subsequent readout is
sequential. Figure 8 shows the integration and readout
sequence for the synchronous shutter. All pixels are light
sensitive at the same period of time. The whole pixel core is
reset simultaneously; 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 readout can occur in parallel or
sequentially.
In the global shutter mode, light integration takes place on

300 W. The value of this resistor is not tested at sort or at final
test. Some modification may be required as the
recommended resistors in Figure 7 are determined by
trade−off between speed and power consumption.
Pipelined Global Shutter
readout are done in parallel. Images are continuously read
and integration of frame N is ongoing during readout of the
previous frame N-1. The readout of every frame starts with
an FOT, during which the analog value on the pixel diode is
transferred to the pixel memory element. After the FOT, the
sensor is read out line by line and the readout of each line is
preceded by the ROT. Figure 9 shows the exposure and
readout timeline in pipelined global shutter mode.
