Delayed Readout
Delayed readout allows images captured by a [FrameStart] trigger command to be stored
temporarily inside the camera (delayed readout buffer) and read out using a
[AcquisitionTransferStart] trigger after capture.This function is useful when executing triggers
simultaneously on multiple cameras.
Note
This function imposes a heavy processing load on the network bandwidth, as images from
multiple cameras are read out simultaneously. The number of frames that can be stored for
delayed readout depends on PixelFormat.
For details, see “Trigger Control” .
ALC (Automatic Level Control) Function
The ALC (automatic level control) function combines the automatic gain control (AGC/Auto
Gain Control) and automatic exposure control (ASC/Auto Shutter Control) functions, and is
capable of handling various changes in brightness.The function operates as follows in
response to changes in brightness.
Change from bright to dark: ASC → AGC

■ To use the ALC function
Set [GainAuto] or [ExposureAuto] or both to [Continuous] mode. Configure the minimum value,
maximum value, etc. for AGC and ASC under [JAICustomControlALC].The target video levels
for AGC and ASC are configured in [ALCReference]. For example, when [ALCReference] is set
to 95%, video levels will be maintained at 95% for AGC and ASC.
