Method of adjusting a desired white color on at least a part of an image by means of a device comprising at least a light source and at least an electro-optical light modulation panel. The light coming from the light source is converted into an image via at least the electro-optical light modulation panel. A light control device co-operating with a light modulation panel is associated with this panel. For adjusting the desired white color, the electro-optical light modulation panel is driven through at least a part to a desired maximum. The part is imaged on the part of the image. The color of the part of the image is adapted to the desired white color by means of the light control device.
A method of adjusting a desired white color on at least a part of an image by means of a device comprising at least a light source and at least an electro-optical light modulation panel, in which method the light from the light source is converted into an image via at least the electro-optical light modulation panel, characterized in that a light-control device co-operating with the light modulation panel is associated with said panel, in which, for adjusting the desired white color, the electro-optical light modulation panel is driven through at least a part to a desired maximum, which part is imaged on the part of the image, whereafter the color of the part of the image is adapted to the desired white color by means of the light control device.
A method as claimed in any one of the preceding claims, characterized in that the color of the part of the image is detected by means of a sensor, in that subsequently the detected color is compared by a control means with a desired white color, and, if the detected color does not correspond to the desired white color, the light control device(s) is (are) subsequently driven by the control means until the desired color corresponds to the desired white color.
A device suitable for generating at least an image, at least a part of which has a desired white color, which device comprises at least a light source and at least an electro-optical light modulation panel, characterized in that a light control device co-operating with the light modulation panel is associated with said panel, said light control device being adjustable when driving the light modulation panel to the desired maximum, so that the part of the image has the desired white color.
