Claim:
1. A method to display a merged image on a display, the method comprising, by a processor: receiving first data that relates to a first image of a real object; receiving second data that relates to a second image of a virtual object, wherein the second image, if displayed on the display, would overlap, in an overlap region, at least part of the first image if the first image were displayed on the display, and wherein the virtual object includes text; identifying an overlap part in the first data that corresponds to the overlap region; clipping the overlap part from the first data that relates to the first image of the real object by copying the overlap part to produce clipped data, wherein the clipped data includes data that corresponds to the first image of the real object in the overlap part; blurring the clipped data by application of a blurring transform on the clipped data, where the clipped data includes data that corresponds to the first image of the real object in the overlap part, to produce blurred data related to the first image of the real object; subtracting the clipped data related to the first image of the real object from the blurred data related to the first image of the real object to produce an additive blur component; adding the additive blur component to the second data related to the second image of the virtual object to produce merged data, wherein adding the additive blur component includes executing a brightness based merge, and wherein executing the brightness based merge includes: generating the merged image to be displayed on the display based on the merged data; and outputting the merged image on the display so that the merged data appears in the overlap region.
