SV305 odd histogram
Posted: Tue Apr 06, 2021 7:21 pm
Hello,
New Sharpcap User and new SV305 owner.
I am wondering how to interpret the histogram spreadsheet I get when save a camera snapshot. The histogram itself is fairly 'fuzzy', meaning the frequency is varying quite a bit as the values change. Below is an example taken from the spreadsheet, which is the result of a white-balanced capture.
Red Green Blue
12043 13520 05
22424 13633 53
15276 14378 65
22163 14821 02
20061 15369 89
14157 15918 04
23912 16200 83
16265 16527 06
This small segment misses the Blue peak, but clearly shows the issue. The frequency of the Green pixels progresses smoothly, while the Red and Blue pixels show wild swings. Does this indicate an A/D problem? NOTE: I added the zeroes to the Blue column to get the numbers to line up properly.
Thanks, Stan
