Description

Jest znanem, ze obrazy czesciowe, zdje¬ te na zmiane przez czerwone i zielone w i- stocie uzupelniajace sie filtry swietlne, wy¬ swietla sie na zmiane czerwonem i zielonem swiatlem podczas gdy ekran jest oswietlo¬ ny niebieskiem swiatlem. Czerwone i zie¬ lone filtry swietlne sa do wyswietlania tak dobrane, zeby w rezultacie wydaly mozli¬ wie czysta bieL Nalezy zwrócic uwage, by niebieskie o- swietlenie ekranu nie bylo zbyt silne, po¬ niewaz w przeciwnym razie wszystkie bia¬ le i szare czesci obrazu bylyby w tej bar¬ wie za silnie odznaczone, a obraz otrzy¬ malby zimny ton, wobec czego sila niebie¬ skiego zabarwienia ekranu winna byc od¬ powiednio dostosowana. Oddanie barwy zóltej przy tern postepowaniu nawel w przyblizeniu nie jest mozliwe.Lepszy rezultat osiaga sie przy poste¬ powaniu, wedlug przytoczonego wynalaz¬ ku, tak, by obrazy czesciowe zdjete przez uzupelniajace sie wzajemnie filtry czerwo¬ ny i zielony byly wyswietlane na ekranie, który prócz tego jest oswietlony niebie¬ skiem swiatlem, w ten sposób, zeby uzyte do wyswietlania czesciowych obrazów czer¬ wone i zielone swiatlo przy zmieszaniu da¬ walo w rezultacie barwe zólta, która uzu¬ pelniona z niebieskiem swiatlem daje bieL PLIt is known that partial images, taken alternately by red and green in fact complementary light filters, are displayed alternately with red and green light while the screen is illuminated by a blue light. Red and green light filters are selected for the display in such a way that they give out as pure white as possible. the image would be too strongly marked in this color, and the image would receive a cold tone, so the strength of the blue color of the screen should be adjusted accordingly. It is not possible to approximate the yellow color in this case. A better result is achieved in the procedure, according to the cited invention, so that the partial images captured by the complementary red and green filters are displayed on the screen, which in addition, it is illuminated with blue light, so that the red and green light used to display partial images results in a yellow color when mixed, which, when combined with blue light, gives a white color
