= Histograms in 333 camera =
It is now (starting with 6.4.22 software) possible to get images with histograms from the 333 cameras.
http://<camera_ip>/histogram.cgi
returns GIF image with 4 histograms - for integral intensity (white) and fro individual colors (RGB)
http://<camera_ip>/pnghist.cgi
returns PNG images and can be configured with additional parameters, such as
http://<camera_ip>/pnghist.cgi?sqrt=0&scale=10&average=10
== pnghist.cgi parameters ==
height - image height, maximal is '''256''' pixels (width is always 256)
draw - draw mode (0..'''2'''): 0 - dots, 1 - vertical bars, 2 - connected dots
fillz - (0/'''1'''), fill zeros - fill gaps of zeros (happens in high contras areas where each sensor count (1 of 1024) corresponds to several output counts.
linterpz - (0/'''1'''), linear interpolation for the filled gaps of zeros. Automatically turns on fillz (above)
sqrt - ('''0'''/1), calcualtes square root fro each histogram value. Relatively increases small values.
colors - (0..'''57'''..63). Bit-mask that controls display of individual and composite components:
1 - red, 2 - Green1 (in red rows), 4 - green 2 (in blue rows), 8 - blue, 16 - white, 32 - both greens combined. So 1+8+32=40 will display R,G and B
rav - ('''0'''...) - running average, averages specified number of pixels to make histograms smooth.
dscale - (..'''3.0'''...) - specifies what fraction of the total height would the histogram occupy iof all the values were the same. The higher the value, the lower the histogram will be displayed
