Figure 24:

Request for 2 Frames in Internal Exposure Mode

In some cases the F_REQ timing is such that the exposure start of FRAME B would trigger the read-

out period of FRAME B to start when the read-out period of FRAME A has not yet finished, causing a

timing conflict.

When using internal exposure mode, the sensor will buffer the start of exposure for FRAME B so that

it starts at a time when the read-out of FRAME B would not cause a timing conflict.

This means that this mode is safer when it comes to F_REQ timing because no read-out cut-offs will

happen, but also that the delay between F_REQ signal and start of exposure is not always predictable

and depends on the circumstances, as shown in Figure 24.

Control Mode 1: External Mode

In external mode, two pulses are needed to request exposure (INT1) and request frame (F_REQ). The

time between these pulses determines the exposure time.

In this mode, the F_REQ pulse will start frame-overhead time and read-out period no matter what

state the sensor is in. This means that a new exposure can only be requested once the read-out of the

current frame has completed, to not cause a cut-off of the current read-out.

When using two exposure groups for HDR imaging, the INT2 pulse controls the exposure of the

second exposure group. Both INT1 and INT2 are level sensitive.
