Introduction to 4K (UHD TV) Universal Test Card

4K (UHD TV) universal test card YE0279 is used to quickly (mainly visually) evaluate the transmission characteristics of 4K (UHD TV) cameras.

At the center of the test chart on a gray background (D = 0.75; transmittance = 18%), a white circle with gray levels and resolution wedges is used for positioning. Four circles with a resolution wedge are arranged on both sides of the center circle.

The 16: 9 format is marked by four arrows on the horizontal and vertical center lines. In addition, four arrows in a circle near the upper and lower edges of the test chart card mark the 4: 3 format.

The white center circle shows four gray levels, each with 11 steps. They increase from D = 0.15 to D = 1.65 in equal linear steps and are used to check the camera's halftone reproduction.

All frequency values to the test card represents CPH (cycles per picture height). In the center circle, three resolution wedges with different frequencies are arranged vertically and horizontally. They range from 200 to 500, from 400 to 1000 and from 800 to 2000 cph. In addition, two 45 ° resolution wedges produce frequencies from 400 to 1000 cph.

In the middle of the test card, and left and right, there are four square 0,45,90 and having an angle of 135 ° inclined line grating. Their gene frequencies 400cph. At an angle of 45 ° and 135 ° of the raster line that is inclined in the horizontal and vertical directions (due to their inclination) to generate a differential frequency.

Eight cylindrical arrangement in such a manner that they can be used for 16: 9 and 4: 3 format. A larger display resolution cruciform wedge. Circular ring may also be used to check the geometry, for marking the resolution in the vertical and horizontal directions. Resolution display is 400,600,800,1200 and 1600cph. The four corners of a circle having a longer wedge resolution. They cross at 640 cph and mark from 400 to 1600 cph.

In the center of the test card, gray and white bar elements are disposed in the region of length 1 (= half of the image height), 2,4,8,16,32 and 64cph. There are five additional short bars from left to right for vertical grayscale, 100 to 900 and 200 to 1800 cph.
