The
‘Reset’
button sends a reset command to the camera that restores its internal state
from the camera internal flash memory. This is the state you find the camera in every time
you power it up. You may want to force it if you find the camera is not operating after your
parameter changes as you expect it to or at all. You will need to
Erase Camera
after
Reset
to re-start the live video preview.
The
‘Cal’
(Calibrate)
button executes a self-calibration of the camera image sensor by
forcing an input offset null operation on the A to D converters behind each column in the
image sensor. This may improve image quality in some conditions. The typical indication to
perform that self-calibration is appearance of the bright vertical stripes in the image.
The Continuous Capture mode underlines most of the user interactions by providing the
live
Video Preview
display. The visual feedback is a necessary background for adjustment
of the camera video capture parameters to match requirements of the specific camera
application.
The
Video
Preview
display area (open rectangle in the picture above), shows live video
from the camera so you can adjust camera capture parameters and point it at the object
you are going to image. Your first step is to communicate what kind of image sensor your
have in the camera: monochrome or color (Bayer filter). Click
Grey
or
Color24
radio
button to reflect your choice. That selection affects
only
the
Video Preview
display.
Captured images will be stored on disk with the intact Bayer color filter information. A
special post-processing procedure,
Debayer
should be run to reconstitute precise color
information in the downloaded video images from the pixel values filtered by the Bayer
pattern in the color version of the camera.
Display of the
Color24
images in the
Video Preview
window can be changed by clicking
on the
Adjust Color
button that will be activated by the
Color24
selection. Again, that
adjustment affects only the
Video Preview
display.
