Abstract

В устройстве экспонирования для экспонирования такого светочувствительного материала, как материал Сайколор, с помощью таких светоизлучающих элементов, как светодиоды, выполняют корректировку условий окружающей среды во время экспонирования, которые изменяются в зависимости от температуры и т.п., для чего динамически изменяют значение тока или напряжения, которое подводят к светодиодам. Поэтому управление продолжительностью экспонирования можно выполнять исключительно для представления многих уровней градации, так что для управления продолжительностью экспонирования не нужно очень высокое разрешение. Следовательно, можно реализовать дешевое устройство экспонирования, которое может печатать изображения с многими градациями. Для экспонирования одиночного цвета с помощью множества светодиодов циклически изменяют уровень градации, который выражают индивидуальные светодиоды, так что можно упростить конструкцию регулятора уровня градации для каждого светодиода. Далее, так как светодиоды используют, по существу, при одинаковых режимах работы, индивидуальные различия светодиодов не играют явной роли. Можно также предотвратить неудобные случаи износа отдельных светодиодов.Международная заявка была опубликована вместе с отчетом о международном поиске.
