either right-clicking on the quadrant itself and choosing your preferred tool, or by
accessing quadrant choices from the Analyzer Mode menu
Views
The Analyzer uses screen layouts with either a Quadrants view or Single view.
Figure 4. Quadrants View Example
Each screen quadrant can be configured to display the image being examined, or
any of the available measurement tools.

Quadrants can also be configured using the top menu bar's Analyzer Mode drop-
down (Figure 7).
Figure 7. Quadrants View Example, Analyzer Mode Drop-Down Configuration
In Single View, the image being examined, or some of the selected measurement
tools, can be displayed full screen.

Drop-Down Menu Navigation
A top menu bar appears when the cursor is moved to the top of the screen. These
menus can be used to select layouts and configure settings. Clicking on a menu
name opens that menu.
Pressing the ESC key also displays the drop-down menus.
Figure 9. Selecting Colorspace Using Drop-Down Menu
When a drop-down menu is displayed:
The currently selected setting is indicated with a (+) in front of that menu item.
The left and right arrow keys can be used to move to an adjacent menu, or
open an additional parameter menu for the current menu selection.
The up and down arrow keys moves the selection up or down that drop-down
menu.
Pressing the TAB key selects the next drop-down menu to the right. Shift+TAB
moves the drop-down menu selection to the left.
NOTE: When the menu bar is not displayed, the TAB key opens the Settings screen. See
"Settings Screen" on page 37 for more information.
Selecting Views with Keyboard
When a drop-down menu is not open, computer keyboard function keys can also
be used to activate the layouts.

Analyzer Modes
The waveform, histogram, and vectorscope are a form of oscilloscope and are
used to monitor video brightness, contrast, hue, and color saturation.
The waveform displays the luminosity or brightness and contrast of the pixels
in the video frame, with the top of the y-axis indicating a high luminosity level,
and the bottom indicating a low luminosity level.
NOTE: Waveform views can be magnified 4x using the Waveform Zoom control. Use the
mouse to move up and down the display.
The histogram shows the number of pixels in relation to a given list of
luminance, or colors in a specic colorspace.
The vectorscope displays values for hue and color saturation. The color
saturation of each pixel in the video frame is shown, with the middle of the
circle indicating a lower saturation level, and the edge of the circle indicating
a higher saturation level. Hue is represented by placement in the 360 degree
angle of the circle.
HDR Image Analyzer v2.0 16 www.aja.com
NOTE: The Vectorscope view can be displayed at either a 75% or 100% size (the
percentage changes the graticules on the Vectorscope, not the rasterized image),
and can be magnified with the Vectorscope Zoom control.
The gamut screen shows a CIE xy gamut graph reporting the color values
present in the image, with a graticule showing the limits for various standards
(709, P3, 2020).
Several Analyzer view modes are available.
Figure 10. Waveform Luminance Mode
Waveform showing only luminance (Y) and no color information. Each pixel on
the graph shows the frequency of the corresponding luminance value in the
given column. Higher luminance value means lighter image content, lighter pixel
means higher frequency of that luminance value.
Figure 11. Waveform Lumi Color Mode
HDR Image Analyzer v2.0 17 www.aja.com
Waveform showing both luminance and color information. Here, in addition
to the Waveform Luminance mode, the graph is colored according to color
information. The hue and saturation of a pixel shows the sum of the dominant
colors having the corresponding luminance value.
Figure 12. Waveform Color Mode
Waveform showing the RGB channels superposed in one graph.
Figure 13. Waveform RGB Color Mode
Waveform showing the RGB channels in a split view, where each graph is shown
in its respective color.
HDR Image Analyzer v2.0 18 www.aja.com
Figure 14. Waveform RGB Mode
Waveform showing the RGB channels in a split view, where each graph is shown
in monochrome.
Figure 15. Waveform YCbCr Mode
Waveform showing luma (Y), blue minus luma (Cb), and red minus luma (Cr) in a
split view.
HDR Image Analyzer v2.0 19 www.aja.com
Figure 16. Waveform YRGB Mode
Waveform showing luminance and RGB channels in a split view, where each color
channel graph is shown in its respective color.
Figure 17. Histogram Luminance Mode
Histogram Luminance is showing the frequency of luminance values throughout
the current image content. Left-hand part is for darker, right-hand part is for
lighter image content.
HDR Image Analyzer v2.0 20 www.aja.com
Figure 18. Histogram Color YCbCr Mode
Histogram Color showing the frequency of RGB channel values throughout
the current image content, superposed. For each channel, the left-hand part
represents image content for “0” or Black, while right-hand part represents image
content for "1" and White. The 0-1 range is a scale, also represented as code
values: (0 = 0,0,0 and 1 = 1023,1023,1023) in 10 bit code value for R, G & B.
Figure 19. Gamut Mode (CIE xy Graph) with Gamut Error
This mode displays a CIE xy Gamut, showing various output referred color gamut
standard limits, and also has Brightness and Gamut bars.
Brightness and Gamut Bars
This view also contains two bars: the brightness bar on the left indicates the
brightest pixel detected, the gamut bar on the right shows if the colors are within
the legal color gamut. See "CIE xy Gamut View" on page 31 for more information.
