Accu-Chart HDU High Definition Universal Chart

The HDU Chart is designed to be an all-round test chart for color, grey scale and resolution, and back focus. It measures 10" x 16.5" and comes with a protective cover that acts as a table-top stand. When used in conjunction with a waveform monitor, any CCD or tube type camera can be calibrated Grey Level response, Color Rendition, Focus and Shading.

The dimensions of the active area of the chart are 16" x 9" conforming to the 16:9 aspect ratio adopted by most HDTV systems. The chart can also be used for standard 4:3 aspect ratio systems by imaging the center portion of the chart.
