The figure shows how the Full External control mode can be used to (from top to bottom):

●

Operate the sensor in Sequential Operation mode.

●

Operate the sensor in Pipelined Operation mode, with the parallel exposure extending

beyond the readout phase.

●

Operate the sensor in Pipelined Operation mode, with the parallel exposure ending

together with the readout phase (gives maximum frame rate).

Except for the invalid timings listed in Figure 40 the requests on REQ_EXP and REQ_FRAME

can be freely placed anywhere by the external controller. This will result in the most flexible

external control possible with this sensor (start and end exposure at any possible time, freely

vary exposure time from frame to frame, interrupt frames being read to start a new readout).

Figure 40:

Full External Mode: Invalid Control Timing

Invalid Control Timing

Sensor Response

FE_i0

REQ_EXP during GLOB

Will disrupt the GLOB execution, causing the READOUT that

naturally follows the GLOB phase to contain corrupted data.

FE_i1

REQ_FRAME during GLOB

Will initiate a new GLOB, followed by READOUT. Image data in this

READOUT will be corrupt.

FE_i2

2 consecutive REQ_FRAME,

without REQ_EXP in between

Second REQ_FRAME will initiate GLOB followed by READOUT.

Since there has not been EXPOSURE, the image data in the second

frame will be corrupt.

FE_i3

REQ_FRAME when sensor is

IDLE

Same as above: READOUT without EXPOSURE results in corrupted

image.

The table below lists some special cases that are not part of the table above and are

therefore not illegal (though they each do have some consequences)

Figure 41:

Special Control Timing

Sensor Response

FE_s0

REQ_EXP during

EXPOSURE

Will initiate a new EXPOSURE, erasing all previously integrated

information. The next REQ_FRAME will initiate a GLOB+READOUT that

will contain image data of only the second EXPOSURE.

FE_s1

REQ_FRAME during

READOUT

Will immediately interrupt the active READOUT to start a new GLOB,

followed by a new READOUT. The image information of the first

READOUT which had not been read will be forever lost. The new

READOUT will be complete and correct (if not violating FE_i2,

Figure 40).

The figure below shows an example of the cases listed in Figure 41.
