Abstract

AN ELECTRO-OPTICAL FILTER (22) TYPICALLY FOR USE IN A STILL OR VIDEO CAMERA (10). THE CAMERA (10) IS PROVIDED WITH A LENS (14) FOR FOCUSING AN IMAGE OF THE SUBJECT (12) ONTO FOCAL PLANE (16) OF THE CAMERA (10). A RECORDING MEDIUM IS PLACED AT THE FOCAL PLANE (16). LIGHT EMANATING OR REFLECTED FROM THE SUBJECT (12) TRAVELS IN AN OPTICAL PATH (20) THROUGH LENS (14) AND ONTO THE FOCAL PLANE (16). LOCATED IN THE OPTICAL PATH (20) BETWEEN THE SUBJECT (12) AND THE FOCAL PLANE (16) IS THE ELECTRO-OPTICAL FILTER (22). THE ELECTRO-OPTICAL FILTER (22) COMPRISES A MATRIX OF INDEPENDENT CELLS (24) ON WHICH RESPECTIVE PORTIONS OF THE SUBJECT IMAGE IMPINGE. EACH CELL HAS A TRANSMISSIBILITY DEPENDENT ON THE INTENSITY OF THE PORTION OF THE IMPINGING SUBJECT IMAGE SO THAT EACH PORTION OF SUBJECT IMAGE IS INDEPENDENTLY FILTERED BY THE CELL (24) ON WHICH IT IMPINGES. THE FILTERED SUBJECT IMAGE COMPRISES THE ENSEMBLE OF FILTERED SUBJECT IMAGE PORTIONS AND CAN BE CAPTURED OR VIEWED AT THE FOCAL PLANE (16). (FIG.1)
