Samsung patents device with projector that slides out to fit screen distance

Samsung has been granted a patent for an electronic device featuring a projector lens that physically slides out from the main body. The system measures the distance to the wall or screen and automatically extends the lens to the correct length to ensure the image is in focus.

Why it mattersThis design could lead to portable projectors that adjust their focus mechanically rather than relying solely on digital processing, potentially improving image clarity for home entertainment setups.

In the filing’s own words

An electronic apparatus including: a main body; a projecting part configured to retract in the main body and protrude from the main body to project an image; a memory storing at least one instruction; and at least one processor configured to execute the at least one instruction, where, by executing the at least one instruction, the at least one processor is configured to: obtain information about a projection plane, identify a protrusion distance of the projecting part corresponding to the projection plane based on the information about the projection plane, protrude the projecting part based on the protrusion distance, and control the projecting part to project the image on the projection plane.

What exactly they claim (claim 1)

1. An electronic apparatus comprising: a main body separated from a projection plane by a distance; a projecting part configured to retract in the main body and protrude from the main body to project an image; a memory storing at least one instruction; and at least one processor configured to execute the at least one instruction, wherein, by executing the at least one instruction, the at least one processor is configured to, in a state in which the main body is separated from the projection plane by the distance: obtain information about the projection plane comprising information about the distance between the main body and the projection plane, identify a protrusion distance of the projecting part corresponding to the projection plane based on the information about the distance between the main body and the projection plane, protrude the projecting part based on the protrusion distance, and control the projecting part to project the image on the projection plane.
