New 3D Camera Test Chart Said to ‘Reduce 3D Headaches’
3DZMISSISSAUGA, ONTARIO: DSC Labs says it’s bringing out a 3D camera test chart that will reduce the deleterious side effects sometimes brought on by looking too long at 3D video images. The 3DZ chart is said to “rapidly identify setup errors in 3D production potentially diminishing eyestrain, headaches and nausea associated with viewing inaccurately aligned 3D images.”

“3D viewing can be an exciting and pleasurable experience when cameras and projection systems are set up accurately. However, misaligned rigs could be responsible not only for contributing to health issues, but also for giving 3D a bad image,” DSC Labs President David Corely said. “While DSC’s ChromaDuMonde and other charts enable precision alignment of color, grayscale and resolution in the X/Y coordinates, the 3-DZ adds the missing third, or Z, dimension that is so vital in stereo imaging.”

DSC says the 3-DZ chart “consists of five LED lights with adjustable brightness for daylight and studio settings.” The four corner lights provide frame alignment, while the one in the center can be used to set interocular distance and convergence. The center LED is adjustable from chart plane to 12 inches in front of the chart surface. There are also horizontal and vertical indices in 100th image width increments.

DSC Labs will have their new 3-DZ chart on display at 2011 NAB in Las Vegas, April 11-14.

You'll never get rid of the headaches. 3D movies cause eyestrain because they fool the brain into thinking the objects on the flat screen are at different distances from the eye. The eye muscles adjust to focus on the distant object, but it's at the same distance as the screen, so the eyes counter adjust, and so on, tiring the eyes and bringing on the headache. As long as 3D movies are projected on a flat screen, the eyestrain and headaches will continue.

With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
