Method for projecting image content onto the retina of a user, image processing device for carrying out the method and an optical system for a virtual retinal scan display

An image processing device, configured to:

• capture image data;
• blank at least one first subset of the image data, thereby generating an active second subset of the image data, wherein the first subset of the image data and the active second subset of the image data make up the total amount of the image data;
• and
• control a projector unit using the blanked first subset of the image data and the active second subset of the image data such that there is always only one eye box generated on a common imaging path, with the same active image data arranged in a region of a first pupil region of the user, wherein the first pupil region surrounds a pupil center, and at least a portion of the eye box is arranged with at least a portion of the active image data within a second pupil region of the user, wherein the second pupil region surrounds the pupil center, wherein the second pupil region is arranged within the first pupil region.

An optical system for a virtual retinal scan display, comprising:

• an image source, which supplies image content in the form of image data,
• an image processing device for the image data;
• a projector unit with a temporally modulatable light source configured to generate at least one light beam and with a controllable deflection device for the at least one light beam for scanning projection of the image content;
• a redirection unit onto which the image content can be projected and which is configured to direct the projected image content onto an eye of a user;
• an optical segmentation element, which is arranged between the projector unit and the redirection unit and is configured to project the image content via at least two different imaging paths onto at least one projection region of the redirection unit, wherein at least some of the imaging paths are individually controllable;
• and
• an optical replication component, which is arranged in the at least one projection region of the redirection unit and is configured to direct the projected image content in a replicated and spatially offset manner onto the eye of the user, so that a plurality of mutually spatially offset eye boxes with the image content is generated;
• wherein the image processing unit is configured to:
• capture the image data,
• blank at least one first subset of the image data, thereby generating an active second subset of the image data, wherein the first subset of the image data and the active second subset of the image data make up the total amount of the image data, and
• control the projector unit using the blanked first subset of the image data and the active second subset of the image data such that there is always only one eye box generated on a common imaging path, with the same active image data arranged in a region of a first pupil region of the user, wherein the first pupil region surrounds a pupil center, and at least a portion of the eye box is arranged with at least a portion of the active image data within a second pupil region of the user, wherein the second pupil region surrounds the pupil center, wherein the second pupil region is arranged within the first pupil region.
