The ‘User’ and ‘Camera’ settings may be changed and applied in real time without having
to click the ‘Apply All Settings’ button by means of a
real-time control slider
at the top
of the window just under the ‘Apply All Settings’ button. To use this slider to change a
setting value, left-click once in the text entry box for the setting you want to change. The
name of that setting will appear above the slider to indicate that this is the control whose
value the slider will be changing. The slider will automatically go to the position associated
with the current value applied for that setting. This is illustrated for the ‘Gamma’ control in
figure 6.3 You can then change the value of that control in real time by sliding the slider.
This real-time control slider is not available for any of the ‘Custom’ settings.
The meaning and behaviour of all the ‘User’ and ’Camera’ settings available for the AF51
have already been described in great detail in chapter 3 so will not be repeated here.
Custom settings
Apart from the options listed in the camera ‘
Image size and FPS for full frame
capture
’ drop down list, all the ‘Custom’ settings are provided by the PARD Capture
program itself and are not dependent on the camera firmware so they will be available for
any camera that can use the PARD Capture software. These custom settings will only be
updated and applied when you click the ‘Apply All Settings’ button – there is no option for
real time control with the slider bar as there is for the Camera and User settings.
The ‘
Image size and FPS for full frame capture
’ drop down list shows all the image
stream sizes and maximum frame rate for each one that are available for the type of
stream format that is currently selected. This is important to realise because it you select
to change the camera stream format then the available image dimensions and maximum
frame rates offered by your newly selected format may differ from the choices shown with
the current image stream format in this drop down list. For the AF51 camera all the image
sizes available for the MJPEG image stream format will also be available for the YUYV
format so image frame size will not be an issue when using this camera. However, the
maximum FPS frame rate will differ between the two stream formats. For MJPEG 30 FPS
will be permitted for all image sized but none of the YUYV stream frame sizes can be
streamed at that rate so you will need to reduce the preview frame rate to a figure that is
compatible with the chosen frame size resolution when changing from MJPEG to YUYV.
Unfortunately, the list of maximum frame rates for the YUYV stream will not be shown in
the GUI until you actually apply the changes. It is not a big problem however because all
that will happen if you choose too high a preview frame rate is that you will get some
warning pop up messages when you apply the changes and the program will
automatically select the highest frame rate available for your chosen image size.
