VIEWING SYSTEM WITH CORRECTION FILTER

摘要

The general field of the invention is that of viewing systems comprising an image processing device (E), the image before processing being called the initial image and the image after processing being called the processed image, a display (D) presenting the image processed by the image processing device, and a viewing device comprising: a first optical element (L1) turning the processed image into an intermediate image, said first optical element comprising a pupil (P); a second optical element (L2) turning the intermediate image into a collimated image intended to be presented to a user, said second optical element being arranged in such a way as to form an image of the pupil at eye (Y) level of the observer, said image being called the eye point (A). The device according to the invention comprises a correction filter (F) disposed at the level of the pupil and arranged in such a way as to ensure at least that an image presented by the display does not undergo any contrast inversion through the viewing device. The image processing consists in modulating the contrast of the initial image according to the spatial frequency of said initial image in such a way that the variation in contrast of the image processed according to the spatial frequency is such that the collimated image is substantially equivalent to the initial image.
