As a result, the measuring instruments used for the research, develop- ment, production, inspection, and measurement of products must also provide higher performance and precision. Such instruments must also offer trouble-free operation and must provide high reliability and uniformity. If measuring instru- ments lack this reliability and uniformity, the results of important research or testing will prove unreliable. Conse- quently, the precision of each measuring instrument used must be carefully checked. The management of measuring instruments is of vital impor- tance. To maintain high measuring accuracy, periodic calibration must be done. For such calibration, standards and measuring devices must be prepared and calibrated ac- cording to higher-level standards, up to and including the national standards, in order to comply with international standards. For this reason, a high level of trace- ability must be established.

  • Color Correction for Video, Second Edition, by Steve Finland +41 52 675 3777 Hullfish and Jaime Fowler
    3 USING SCOPES AS CREATIVE TOOLS The next two important tools — after the video monitor itself — in analyzing a video image are a waveform monitor and vector- scope. There are three general categories of scopes available. The fi rst type is completely hardware based, with the waveform and vectorscope trace and graticule presented on a screen built into the scope (see Figure 3-2 ). The second type uses dedicated hard- ware to display the scopes on a separate computer display or as an overlay on your video monitor (see Figure 3-1 ). This is often referred to as a rasterizer or hybrid. The third type is soft- ware based using a video card, with the resulting image of the scope displayed in the software UI on your computer monitor (see Figure 3-3 ). Choosing Your Scope One of the main aspects that distinguish good scopes from bad is the resolution of the trace. One of the main aspects that distinguish good scopes from bad is the resolution of the trace. The trace, which is the scope ’ s visual representation of the video signal on the monitor, has a much higher resolution in hardware-based scopes and rasterizers. The resolution of the trace is particularly important when analyzing the video signal to be color corrected. This is where almost all software scopes — and even some hybrid scopes that are displayed on the video monitor — suffer. Hybrid scopes presented on a com- puter monitor are preferable to those presented on a video monitor because of the increased resolution possible with computer CRTs or LCDs.
