Claims (3)

1. Устройство для использования с решеткой из М х N возбуждаемых зеркал, включенной в оптическую проекционную систему, для коррекции величины вводимого элемента изображения с использованием предварительно определенной скорректированной величины для соответствующего возбуждаемого зеркала, где М и N - целые числа, отличающееся тем, что содержит средство для гамма-коррекции величины вводимого элемента изображения, устройство для хранения предварительно определенного множества скорректированных величин для упомянутых М х N возбуждаемых зеркал, средство для формирования адресных данных, характеризующих местоположение вводимых элементов изображения, cредство для поиска, в соответствии со сформированными для вводимого элемента изображения адресными данными, предварительно определенной скорректированной величины из скорректированных величин хранимого предварительно определенного множества, и средство для коррекции гамма-скорректированной величины вводимого элемента изображения с использованием найденной скорректированной величины для получения скорректированной величины выводимого элемента изображения.1. A device for use with a grid of M x N excited mirrors included in an optical projection system for correcting the magnitude of an input image element using a predetermined corrected value for the corresponding excited mirror, where M and N are integers, characterized in that it contains means for gamma correction of the magnitude of the input image element, a device for storing a predetermined set of adjusted values for the said M x N excited s mirrors, means for generating address data characterizing the location of the input image elements, means for searching, in accordance with the address data generated for the input image element, a predetermined adjusted value from the adjusted values of the stored predetermined set, and means for correcting the gamma-corrected value of the input element of the image using the found adjusted value to obtain the adjusted output value of the picture element. 2. Устройство по п.1, отличающееся тем, что каждая из скорректированных величин, включенная в предварительно определенное множество, состоит из 8 разрядов, а самый старший разряд 8-разрядной скорректированной величины указывает на отклонение возбуждаемого зеркала, соответствующего вводимому элементу изображения, в положительном или в отрицательном направлении. 2. The device according to claim 1, characterized in that each of the adjusted values included in the predefined set consists of 8 bits, and the most significant bit of the 8-bit adjusted value indicates the deviation of the excited mirror corresponding to the input image element in a positive or in a negative direction. 3. Устройство по п. 2, отличающееся тем, что дополнительно содержит средство для ограничения скорректированной выходной величины элемента изображения, если она выходит за пределы предварительно определенного диапазона величин элемента изображения. 3. The device according to p. 2, characterized in that it further comprises means for limiting the adjusted output value of the image element, if it falls outside the predefined range of values of the image element.
