Raw mode is only available for colour cameras supporting both RGB and raw data transfers. The Camera pane allows the preview to be turned on and off (this should not affect capture to files), to set the application to a dark red colour for nighttime use and for enabling 16-bit mode, 2×2 binning and raw mode for cameras supporting those features.ġ6-bit mode is currently only enabled for mono cameras, as is 2×2 binning. Controlling the camera and capture Camera/Display Settings Smooth Hue and VNG (Variable Number of Gradients) may well be too computationally intensive for many machines. Bilinear is slightly slower, but does a far better job and should be preferred. “Nearest neighbour” is fast but low quality. The final set of options used allow the algorithm for the raw to RGB conversion to be selected. GBRG is the correct pattern for the TIS cameras that I have tested.

Note that at one time the software TIS provided with their cameras cropped off the first line of the image so the pattern they document may not be the correct one to use here. It is usually fairly obvious when they aren’t. If you’re not sure it may be helpful to set up during the day and change options until the colours look correct. The second group of options select the CFA pattern to use. The last choice is probably not very useful. Either just the preview window can be converted to RGB, in which case data written to files will remain in raw form, or both can be converted to RGB, or just the data written out. The first two options here set the handling of raw colour data when the “Demosiac” selection is made from the “Options” menu. Normally the histogram will stay on top of all other windows, but the second option here allows that behaviour to be turned off.

When the image is RGB, the histogram can be displayed either as one histogram with the three colour graphs laid on top of each other, or as three separate graphs. The number of runs and the delay between them can be configured, then click “Enable Autorun” to set oaCapture start next time the capture button is clicked in the capture pane. AutorunĪutorun enables a sequence of capture runs to be completed one after the other. Sets the names of the filters that can be selected in the “Filter” menu in the capture panel. These are then available to chose from the “Profile” menu in the capture settings panel. A meaningful name for the saved settings can be entered in the left-hand panel. ProfilesĪdding a profile saves the current camera settings for later use. This contains the camera settings used when the data was captured. “Write capture settings to file” enables writing a file of the same name as the file of captured data, but with a “.txt” extension. Hopefully most of the other settings should be self-explanatory. If the “Load and Save Settings Automatically” option is selected then any saved program configuration will be loaded when the program starts and similarly saved when it exits. The “Settings” menu control configuration of the application behaviour:Īll these options open the same configuration window at a different tab. This can be just for the preview image or for both the preview image and the frame written to an output file.

“Demosiac” enables conversion of raw colour data from monochrome to full colour. Flipping raw colour images may result in unexpected behaviour as the original colour mask may no longer be suitable. If the camera supports this in hardware then the flipping will be done that way, otherwise in software. “Flip X” and “Flip Y” flip the image about the vertical and horizontal axes respectively. “Reticle” displays a reticle over the captured image in the preview window. “Histogram” opens a new window to display a histogram for the captured data. The “Options” menu enables various components of the application: In this case a ZWO ASI120MC has been found via the ZWO ASI SDK, and a TIS DFK21.AU618 using the Linux V4L2 kernel interface.

“Disconnect” disconnects the camera and “Rescan” rescans to update the camera choices after cameras have been added or removed, so it is possible to connect a camera and use it after the application has started. This shows any currently recognised cameras and the interface used to connect to them. The current configuration is saved when the program exits unless configured otherwise. First is the “File” menu:Īt the moment the “Save” and “Reload” configuration options do nothing, so “Quit” is the only useful choice here. Menus for controlling and configuring the application itself appear at the top. The main controls are at the top and there’s a status bar at the bottom with a scrolling area for previewing the image from the camera in between. After starting oaCapture you should see a screen like this:
