Patent ID: 11989801

Abstract:
Method of calibrating a computerised colour vision test and method of testing colour vision on a computer The invention relates to a method of calibrating a colour vision test for testing colour vision under given ambient lighting conditions, which colour vision test is to be displayed on a colour display (12) of a computer (10) having at least one input interface (14), characterised by displaying a calibration test on the display (12) under given ambient lighting conditions to a person with normal colour vision before starting the colour vision test, displaying within at least one measuring region (31) of the display (12) a colour determination task requiring user input as a part of the calibration test, reading the user input through at least one input interface (14) of the computer (10), evaluating the read user input and determining as a result of the evaluation a display error resulting from a combination of a colour reproduction capability of the display (12) and an effect of the ambient lighting conditions on colour vision, and determining a modification to the colour vision test from the display error that corrects the colour vision test with respect to the display error. The invention further relates to a method of testing colour vision using the calibration method, as well as to a computer and computer program configured for performing such methods. The invention further relates to a colour discrimination test, to a colour identification test and to a combination of the two tests.
