Image Acquisition
You can now select the area to be displayed by dragging the black rectangles
along the characteristic curve or carry out automatic optimization by clicking
on the corresponding buttons.
A histogram of the gray and color values will be displayed which makes the
gray and color distribution visible.
The
Best Fit
,
Min/Max
and
Linear
buttons can be used to quickly adjust the
histogram display. You can influence the display by clicking on the
Log
or
Skip
buttons.
Best Fit
calculates in the current histogram the values which exclude 1‰ of
the pixels contained in the image. The color/color range calculated in this way
is displayed on the screen. (You can adjust the value of 1‰ to suit your
requirements).
Min/Max
displays on the screen the smallest and largest gray or color value
present in the image.
Linear
displays on the screen the total possible value range.
Log
displays the histogram in a logarithmic scaling, allowing you to effectively
evaluate histograms of images with high dynamics.
Skip
: By using the
Skip
function the maximum values at the upper and lower
end of the histogram are omitted during the scaling of the display.
The
,
and
scrollbars can be used to change the brightness,
contrast and gamma of the display. This can also be achieved by dragging the
individual "handles" of the characteristic curve in the histogram. You can
adjust the brightness and contrast by changing the left or right-hand end
points of the characteristic curve individually or by shifting the entire line using
the center "handle". The gamma value can be changed by shifting both
"handles".
Click the
Save
button to store the current settings. You can use these settings
when displaying another image by clicking the
Restore
button. This enables
you to compare different images.
