      Resolution test card Introduction to geometric / coincidence test cards

      Geometric / coincidence test card has a horizontal 23 horizontal and vertical 53 grid on a stripe background. 3 grid lines from the middle of the three-row grid. The width of the grid line is 0.15% of the image width. The diameter of the large circular line is 83% of the height of the image, and the diameter of the five small circles is 25% of the image height.

      4 resolution resolution is distributed at 0 °, 45 °, 90 ° and 135 ° of the large circle, corresponding to the 2-10 MHz signal frequency (8 MHz and 600 line mark ends).

      Geometric / coincidence test card application

      The test card is designed specifically for operational adjustment and control of the TV camera.

       The linear scan of the circle can be roughly visualized.

      The role of the grid line is to adjust the positioning.

      The role of perseverance is to test the resolution.Resolution test card
