On selecting the Extension settings tab, the extension control will appear, if the device
supports extension unit. The See3CAM_CU51 camera has some additional controls and
features and these are not quite common controls and hence they are not included in the
standard UVC controls, but listed as Extension controls.
The Extension Unit Menu is used to select these extended HID controls of
See3CAM_CU51. It can be used to control master mode, trigger mode, manual exposure,
exposed image capture and select the torch modes. This can be done by clicking the
appropriate controls of the Extension Settings.
7.6.1
Master Mode
The Master Mode of operation can be considered as a free-running mode of the camera.
The camera is configured for a preview resolution and still resolution. The application is
started and the Master mode is chosen and the application starts streaming the video. This
is a simple mode of operation for the camera without any external trigger capability.
In master mode of See3CAM_CU51 in Linux, there are two methods of still image capture.
They are:
1.
Software Still Capture
2.
Hardware Still Capture
e-con systems has found an intelligent method to facilitate still image capture by using the
sample application QtCAM. In Master Mode still image can be taken by using any of the
methods, and also in all available resolutions using any brightness value.
If the user wants to take an image in the preview resolution the user should first select the
path of image storage and then click on capture image icon or give a trigger input through
the DIN connector to get the image in the same resolution. If the user wants to take an
image in another resolution, the user must first switch to that resolution and then take the
image.
Both Software and Hardware still capture methods are supported in the Master mode of
See3CAM_CU51.
