Abstract (en)
[origin: WO2015015061A1] The invention relates to a method for determining the operation of an image projector for projecting images onto a screen of a projection room. In particular, the method is implemented by computing means (PC) and comprises the following steps: driving the projector (PROJ) so as to project onto the screen (ECR) a test card comprising a distribution of patterns of different hues, acquiring an image of the test card on the screen by a picture taking apparatus (CAM), and applying a processing of the image acquired, so as to determine at least one deviation of chrominance of the image acquired with respect to a predefined number of colours.
