Figure 99: View menu – Histogram window
The histogram always displays 256 values per channel. For color modes with a bit depth of more than 8 bits, the function evaluates the 8 most significant bits (MSBs).
The following options are available:
• | Channel With the Red, Green, and Blue check boxes, you can enable or disable the display for each color channel. Avg. displays the average of each color value. For monochrome images, the average grayscale value is displayed. |
• | Outlined The Outlined check box enables you to toggle the color value display between an area diagram and a line diagram. |
• | Logarithmic If you select this check box, the values are displayed with logarithmic scaling. |
• | Show Bayer RGB This function is only available when a color camera is running in Direct raw Bayer mode. If you select this check box, the histogram represents the individual Bayer color components as red, green and blue channels. |
