    • In an aspect, a moon appearance generating system (1) is configured for providing an enhanced depth perception to imitate a sky scene, for example, a natural sky scene at night. The moon appearance generating system (1) comprises a luminous device (7) with a primary light emitting area (9) that is configured to provide, when the moon appearance generating system (1) is operated to imitate the sky scene, a two-dimensional spatial profile of a luminous flux density across the primary light emitting area (9) with a mean luminous flux density value of at least 5 lm/m2, a maximum luminous flux density value of less than about 150000 lm/m2, wherein the mean luminous flux density value is at least 2% of the maximum luminous flux density value; and a frame structure (25) providing an exit aperture (5) through which the primary light emitting area (9) is completely viewable from within an enhanced depth perception observation range (33), wherein the exit aperture (5) is associated with an inner frame line (25A) that surrounds at least an area of 20 cm width and 20 cm height.
