    摘要: A test and measurement instrument converts digital data that represents an input signal into a plurality of bitmaps, and then subtracts one of the bitmaps from another one of the bitmaps to produce a difference bitmap. The difference bitmap does not contain density values that are common to the two bitmaps, but instead only contains the density differences between the two, thereby revealing very small density variations in the presence of large density values. In some embodiments, the difference bitmap is displayed on a display device. In other embodiments, the difference bitmap is used to generate a trigger signal.

    摘要: A test and measurement instrument processes digital data that represents an input signal to produce a target image, and then uses a computer vision technique to recognize a signal depicted within the target image. In some embodiments, the location of the signal within the target image is identified on a display device. In other embodiments, the location of the signal within the target image is used to perform a measurement. In other embodiments, when the signal is recognized, a trigger signal is generated that causes digital data that represents the input signal to be stored in a memory.

    摘要: A test and measurement instrument includes an input for receiving an input test signal and a separator that separates a data array of the input test signal into a number of different data bins. Each data bin includes a number of data points. A selector is included that determines whether the data points within a present bin of the total bins represent signal or noise. When the present bin contains noise, a processor generates a first output for the present bin. Instead, when the present bin contains signal, the processor generates a second output for the present bin. The bin outputs can then be combined to make an output array, such as a waveform display, for the instrument.

    摘要: A system and method for automatic measurement of video parameters for a video sequence using a video processor that has a software waveform monitor implemented as an integral part of a video processing application run by the video processor. Each frame of the processed video sequence, either in realtime as processed by the video processor, in near realtime after storage by the video processor in a storage device, or in the background for each video sequence stored in the storage device, is analyzed against specified parameters for legalization and/or color balancing of the video sequence. The analysis results may be reported as a display in several forms—an error image map, an error log, a timeline graphic, etc. The analysis results may also be provided to the video processor for automatic correction of the video sequence when the specified parameters are not satisfied.
