Histogram
The histogram area displays the statistical values of the currently displayed image, including the maximum
value, minimum value, average value, and mean square deviation, where the peak indicates the maximum
brightness of the image. Using the AUTO button, you can perform an automated stretch operation to
display the image correctly before processing and using the Mini symbol you can enlarge the graph for
finer adjustment of the image. It is recommended to keep "Automatic" on. The Reset button- resets the
stretch if required.
