Изобретение относится к телевизионной (ТВ) технике и может быть использовано в системах контроля качества ТВ-устройств. Известен способ квалиметрической оценки качества ТВ-изображений. Новым является то, что при использовании предложенных D-фазных тестовых сигналов и алгоритмов их обработки, способ позволяет, например при D = 3 или 2, сократить время анализа искажений тестовых сигналов за счет уменьшения числа их фаз с 4-х до 3-х, необходимых для выделения опорной низкочастотной компоненты и огибающих амплитуды радиоимпульсной компоненты и фазы радиоимпульсной компоненты без применения детектирования сигнала. Это позволяет повысить достоверность квалиметрической оценки качества изображения.The invention relates to a television (TV) technique and can be used in quality control systems for TV devices. There is a method of qualimetric assessment of the quality of TV images. New is the fact that when using the proposed D-phase test signals and processing algorithms, the method allows, for example, at D = 3 or 2, to reduce the time of analysis of test signal distortions by reducing the number of their phases from 4 to 3 necessary for the selection of the reference low-frequency components and the amplitude envelopes of the radio pulse component and the phase of the radio pulse component without applying signal detection. This allows you to increase the accuracy of qualimetric assessment of image quality.
