FIELD: physics; information technology.SUBSTANCE: invention relates to the field of digital image with an increased dynamic range. A method of producing images with increased dynamic range is that the required dynamic range image is divided into parts, are executed in parallel shooting in each part of the range, obtained when recording discretized and quantized image with a reproduction characteristic set in within separate dedicated parts of the dynamic range, combine the received video data in the total image, the amplitude of the sampled signal quantized components of each of the obtained images is converted into a set of logical units on each level of quantization in accordance with the magnitude of the signal that are complementary logical zeros, formed of the transformed data for all the images obtained total array of logic levels with total total number of levels of all of these images P, which then all quantization levels 1 to P produce a sequence of pairwise comparison of logic signals for pairs of levels K and K + 1 logical OR operation and I.EFFECT: provision of improved performance and efficiency of work of video information devices.2 cl, 5 dwg |
