1. A control unit for controlling luminance in a space, said control unit being configured to:
- estimate a trajectory of a target relative to said space, wherein said estimated trajectory runs from a first location with a first luminance level to a second location with a second luminance level, and wherein said estimated trajectory comprises at least one intermediate location, with at least one intermediate luminance level, disposed between said first location and said second location; and
control said luminance in said space based on the estimated trajectory, on said first luminance level and said second luminance level, and on a function rate corresponding to an adaptability of an eye of the target to changes in luminance such that, at a given instant, said luminance in said space is at said first luminance level at said first location, at said at least one intermediate luminance level at said at least one intermediate location, and at said second luminance level at said second location along said trajectory, wherein said at least one intermediate luminance level is between said first luminance level and said second luminance level and wherein said control unit is configured to set said at least one intermediate luminance level and said second luminance level based on said function rate.

12. A method for controlling luminance in a space, comprising the steps of:
-
estimating a trajectory of a target relative to a space, wherein said estimated trajectory runs from a first location with a first luminance level to a second location with a second luminance level, and wherein said estimated trajectory comprises at least one intermediate location, with at least one intermediate luminance level, disposed between said first location and said second location; and controlling said luminance in said space based on the estimated trajectory, said first luminance level and said second luminance level, and on a function rate corresponding to an adaptability of an eye of the target to changes in luminance, such that, at a given instant, said luminance in said space is at said first luminance level at said first location, at said at least one intermediate luminance level at said at least one intermediate location, at said second luminance level at said second location along said trajectory, wherein said at least one intermediate luminance level is between said first luminance level and said second luminance level and wherein said at least one intermediate luminance level and said second luminance level are set based on said function rate. - View Dependent Claims (13, 14, 15)
