the colors from the Bayer Array. You can select from the following demosaic
methods:
None.
Image displayed as it comes from the camera
Green to Greyscale
. Only the green is used to convert the image to
greyscale. Missing pixels are calculated by linear interpolation.
Nearest Neighbour Interpolation to Greyscale.
Each pixel is converted
to color one by the Nearest Neighbour method (see below) and then a grey
value is calculated as a sum of RGB/3.
Bilinear Interpolation to Greyscale
. Each pixel is converted to color one
by the Bilinear Interpolation method (see below) and then a grey value is
calculated as a sum of RGB/3.
Show Bayer Mosaic as RGB
. The Bayer pattern is shown in color.
Nearest Neighbour Interpolation to RGB
. Nearest Neighbour method
uses the nearest pixel of desired color in the direction left or top. It is the
fastest method, giving rough results.
Bilinear Interpolation to RGB
. Missing colors are linearly interpolated from
nearest 2 or 4 pixels of the desired color. Fast method, which gives
reasonable results, images are smoother, but less sharp.
Variable Number of Gradients to RGB
. Method, which is commonly
referred as the one giving the best results. First an 5x5 environment of the
pixel is evaluated and a sum of gradients is calculated. Then gradients not
higher than calculated threshold are used for color calculation. This algorithm
is the slowest, approx. 40x slower than bilinear interpolation.
Pixel Grouping to RGB
. It is about 5x faster than Variable Number of
Gradients, but giving about the same results - on some places even slightly
better, on some places slightly worse. It also takes the 5x5 environment, but
the evaluation of the gradients is simpler and thus faster.
White Balance
By pressing this button the current image is taken as a reference for white
balance and a lookup table is calculated, which is applied to subsequent
acquired images.
Note that the decoding is done by software, in PicSight demo.

Info
This tab is useful in case you are testing the transfer bandwidth of your LAN
connection. In case there is too high traffic on the networks, some frames may
be aborted. The number aborted frames since the acquisition was initialized is
shown here.
