Camera Operating Modes
There are six operating modes, each of them being identified by a symbol as follows:
First letter of the symbol:
- R (Reset) : the line-scanning process starts upon receiving a signal from the frame grabber.
- S (Synchronous) : the line-scanning process is free-running.
Second letter of the symbol:
- G (Grabber) : the exposure control is exercised from the frame grabber.
- C (Camera) : the exposure control is exercised from within the camera.
- P (Permanent) : there is no exposure control, i.e. the exposure is permanent.
Note. Some cameras may be configured to behave according to more than one mode from the list before. However, in a given application, only one mode is in use.
Controlled cameras
Symbol |
Meaning |
RG |
Grabber-controlled line-scanning, grabber-controlled exposure, single signal |
Exposure duration defined as the active duration of a pulse over a single line issued by the frame grabber. |
|
RG2 |
Grabber-controlled line-scanning, grabber-controlled exposure, dual signal |
Exposure duration defined as the active duration of a pulse over a dual line issued by the frame grabber. |
|
RC |
Grabber-controlled line-scanning, camera-controlled exposure |
Exposure duration set through camera switches or serial control. Line-scanning is triggered by a pulse over a line issued by the frame grabber. |
|
RP |
Grabber-controlled line-scanning, permanent exposure |
No exposure control capability, resulting in permanent exposure. Line-scanning is triggered by a pulse over a line issued by the frame grabber. |
Free-running cameras
Symbol |
Meaning |
SC |
Free-running, camera-controlled exposure |
Exposure duration set through camera switches or serial control. Line-scanning is free-running. |
|
SP |
Free-running, permanent exposure |
No exposure control capability, resulting in permanent exposure. Line-scanning is free-running. |
