Abstract

В предлагаемом изобретении данные изображения объекта формируются при осуществлении предварительного формирования изображения с одновременным изменением чувствительности восприятия на множестве этапов непосредственно перед началом нормальной операции формирования изображения объекта; вычисляют абсолютное значение разности данных яркости для соседних элементов сформированного изображения объекта; и в качестве оптимальной чувствительности восприятия устанавливают чувствительность восприятия, характеризующуюся максимальным абсолютным значением разности из вычисленных абсолютных значений разности в системе фотодетекторов, содержащей матрицу фотодетекторов, образованную путем размещения в двумерный массив множества фотодетекторов, схему управления, предназначенную для подачи сигнала управления в фотодетекторы, и контроллер, предназначенный для управления операцией формирования изображения объекта и установкой чувствительности.Международная заявка была опубликована вместе с отчетом о международном поиске.
