The Tektronix 3D Monitoring Support Option for 5250 Waveform Monitor features camera alignment and tools for 3D production/post-production applications. A 3D image is comprised of a left eye and right eye image to be fed as 2 separate HD-SDI signals or combined within a 3G level B format. Alternatively, the 3D signal can be carried in a single HD-SDI signal as a side-by-side image for the left and right images. A variety of different 3D monitoring modes are available within the instrument to assist the user in determining the difference between the left eye and right eye views. From this disparity difference between the 2 left and right images, the depth of an object within the image can be determined.

For measurement of the depth of an object within the image (S3D), a disparity grid can be overlaid over the picture with a horizontal disparity between 1 to 15% of the screen width and a vertical disparity of 50%, 25%, or 10% that can be selected by the user. The horizontal and vertical position controls allow the disparity grid to be moved around within the picture display to gauge the depth of objects within the image. A set of disparity cursors are also sold separately for precise measurement of horizontal disparity of an object between the left and right eye images. The readout is given of the pixel difference between the cursors and the percentage of disparity of an object.

The Quad Diamond display (S3D) simplifies stereoscopic camera alignment by showing a disparity histogram of the left and right signal from a signal level of 0 to 100% vertically for each of the components: luma, red, green, and blue. If the 2 cameras are well balanced, then the trace will form a vertical trace for each of the diamonds. A deviation in the trace indicates an imbalance between the left and right eye images that should be corrected using the various camera controls until the trace becomes vertical. This display can also be used in post-production for aiding the editor and perform color correction on the left and right images.

For monitoring purposes a variety of displays such as Difference Map, Red/Cyan Anaglyph, Green/Magenta Anaglyph, and Checkerboard Displays can be set up within the Picture mode. These modes help the user compare the disparity between the left and right images and can assist in interpreting the depth of the objects within the image.

Difference Map Display
A subtraction of the 2 luma video signals L-R or R-L to produce a grayscale difference map image and see the difference between the left and right images.
Red/Cyan Anaglyph Display
The left image is shown in red and the right image is shown in cyan, with identical left and right objects shown in monochrome. This allows the user to isolate differences between objects and gauge the depth of the object within the image.
Green/Magenta Anaglyph Display
The left image is shown in green and the right image is shown in magenta, with identical left and right objects shown in monochrome.
Checkerboard Display
This picture display shows a block of the image from the left eye and then the next block shows the image from the right eye in a 16×9 checkerboard pattern. This helps the user compare the levels and color of the signal between the left and right images.
