Introducing Sencore's Patent Pending 3D Video Test Patterns

November 4, 2010

The True 3D Performance What is the true performance and calibration accuracy of a 3D display? As 3D displays and projectors shift into high gear for manufacturers, installers and home theater enthusiasts the big question is how do you accurately test them? After all, the magic of creating the 3D depth of field and immersion into the movie scene relies on left/right image timing accuracy, left/right image positioning accuracy and minimizing left/right image crosstalk. Things you can’t measure by looking at conventional pictures or scenes! D Crosstalk Patent Pending: Exclusively designed with mirrored black vs. white level sections, in the left and right images so you ideally see a 50% gray screen pattern with a black center line when viewed directly or through 3D glasses. This pattern allows you to close your left eye to see the right image and vice versa. It dynamically and conveniently tests a display’s true 3D performance of left/right image timing, positioning and crosstalk. 3D Color Wheel This 3D test pattern includes 3D suspended color wheels of all primary and secondary colors and white. Each color wheel is equal depth, distance and alignment with adjacent wheels forming a straight line. This pattern provides a general test of 3D operation, color performance, and positioning accuracy. 3D Cascade A cascading grayscale image tunneling to the rear on top and protruding out of the display on the bottom in 5% steps from black to 50% (top) and 50% to white (bottom). This pattern tests the overall 3D depth of field, analyzes grayscale tracking through the entire 3D depth of field, and provides an accurate black level reference for calibration at the extreme depth of 3D viewing where black level calibration accuracy is most important. 3D Decoder An image with SMPTE level primary colors (bottom) and secondary colors (top) with matching sections on the outside edge and middle of the display. This pattern analyzes a display’s 3D color processing, decoder performance and 3D color presentation. It provides accurate 3D color level and tint calibration for both recessed or protruding 3D colors using a blue filter calibration technique and the display’s 3D glasses. 3D Pluge An image with 3D protruding black, below black and above black reference sections. When viewed in 3D with shutter glasses it provides a conventional reference for setting black level. 3D Box An image with a center box that protrudes forward from the display when viewed in 3D. This pattern can be used with a colorimeter to test and calibrate the display’s color temperature in a 3D mode. These 3D test pattern images are copyright images exclusive to Sencore and can be added to the Sencore MP500 HDMI Generator/Analyzer. The MP500 then provides the 3D analyzing patterns formatted with popular Active Shutter HDMI signal types and provided with proper HDMI 1.4a Vendor Specific InfoFrame signals.
