Chunk Data Function
The Chunk Data function adds camera configuration information to the image data that is
output from the camera. Embedding camera configuration information in the image data
allows you to use the serial number of the camera as a search key and find specific image data
from among large volumes of image data. In addition, when images are shot with a single
camera in sequence under multiple setting conditions, you can search for images by their
setting conditions.

Configuring Chunk Data
1
Set [ChunkModeActive] to [True].
2
Select the items of information you want added to image data with
[ChunkSelector], and set [ChunkEnable] from [False] to [True].
The Chunk Data function settings cannot be changed during image output. To change the
settings, stop Acquisition.
Caution
Note
When [ChunkModeActive] is set to [True], [ChunkImage] is automatically set to [True].
*) For items that can be added to image data as Chunk Data, refer to [n) ChunkDataControl]
in the setting item list.
Delayed Readout
Delayed readout allows images captured by a [Frame Start] trigger command to be stored
temporarily inside the camera (delayed readout buffer) and read out using a
[FrameTransferStart] 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.
* About delayed readout buffer size, refer to “Trigger Control”.
