Claim 0:
1. An imaging system for a head-mounted display, HMD, device, the imaging system comprising:
a holographic image generator for generating a holographic image including a virtual object to be displayed in an external scene;
a light attenuator for forming part of a display to display the external scene;
a camera to capture the external scene; and
at least one controller configured to:
determine, based on the virtual object, an attenuation pattern, for rendering a filter area at the light attenuator; and
determine, based on the captured external scene, a compensation pattern for compensating at least part of the filter area,
wherein the holographic image generator projects the generated holographic image onto the light attenuator such that the virtual object and the compensation pattern are shown in the filter area.
