Image analyzer Histogram |
|
On the tab there is the Image brightness histogram.
On X axis there are brightness levels from 0 to 1. On Y axis the relative number of pixels with each brightness level is shown. Maximum number of pixels of one brightness level is considered to be 100%.
|
When moving the cursor over the histogram, the following data is displayed separated by colon: BRIGHTNESS LEVEL: RELATIVE NUMBER OF PIXELS WITH THIS BRIGHTNESS LEVEL.
When moving the cursor over the image, brightness level at cursor point will be displayed in the same place.
Using the Scale combo box you can increase histogram vertical scale. By increasing the scale, brightness levels, having small number of pixels, become visible.
Using Show/hide histogram in the window button, it is possible to show histogram in increased scale instead of the image itself.
Below there are combo boxes, using which you can change Brightness and Contrast of the source image. After selecting coefficient of change, click the Apply button.
You can apply the same filter many times. |
