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.

Figure 5. Quadrants View Example, Alternate Configuration

The tool or image in each quadrant can be selected by right-clicking on that

quadrant to open a drop-down selection menu for that quadrant (Figure 6).

Figure 6. Quadrants View Example, Right-click Configuration

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.

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.
