HALCON Image Acquisition Interface for GINGA++ Boards

This document provides information about the camera file naming convention used by the HALCON Ginga++ interface.

Camera File Naming Convention

The name of the camera file is described according to the camera name and the way how to control it. It is separated into several blocks by camera name, scan format and shutter mode:

[Camera Name] Name of camera. Symbols like "-" are removed.

[Scan Format] Video signal format of the camera and the number of signals (single or dual tap) as shown below:

	IL	Interlace
	FLD	Non-interlace (field grabbing)
	NI	Non-interlace (progressive frame grabbing)

The number of signals in case of a dual video tap camera:

	SINGLE	Single tap
	DUAL	Dual tap

[Shuttering] Shutter mode of the camera:

	NORM	The video signal, which is the continuous output from the camera, can be grabbed by the software timing. The camera runs in free running mode. Each grab starts with the vertical sync signal of the video just after a grab command like grab_image is called.
	TRIG_FREERUN	The video signal, which is the continuous output from the camera, can be grabbed by the shot (trigger) signal from the external device or shot operation by software trigger. the camera runs in free running mode. Each grab starts by the vertical sync signal of the video just after external shot signal input or software shot operation using grab_image or grab_image_async.
	TRIG_DEMAND	Reset shutter is made by a trigger signal given to the camera from the GINGA++ board. The camera trigger signal is given at the timing of shot signal from external device (external trigger) or shot operation (software trigger, see above). The camera can be reset by the shutter operation and outputs the video signal at the shot signal timing. In case that several cameras connected to a GINGA++ board are reset by the same shot signal timing, these cameras can grab simultaneously.

Examples

• Sony XC-55, interlace scan, free running without reset shutter:
  
  XC55_IL_NORM
  
  
• Teli CS-3720, progressive scan, single video, grabbing by shot signal under free running mode:
  
  CS3720_NI_SINGLE_TRIG_FREERUN
  
  
• Teli CS-3720, interlace scan, dual video, grabbing with reset shutter by external shot signal (external trigger) or software shot operation (software trigger):
  
  CS3720_IL_DUAL_TRIG_DEMAND
