Electronic device and method for controlling the electronic device thereof

An electronic device comprising:

• a projection part;
• a memory storing at least one instruction;
• at least one processor,
• wherein the projection part includes a split prism and is configured for transmitting a part of light emitted from a light source in a front direction and reflecting a remaining part of light on at least one inclined surface in a lateral direction;
• and
• a sensor,
• wherein the at least one processor is configured to:
• acquire information on at least one of a user position, a position of the electronic device, or a type of projection surface based on a sensing value acquired by the sensor,
• determine an image segmentation type based on the information on at least one of the user position, the position of the electronic device, or the type of projection surface,
• convert an image into a multi-sided image to be projected to a plurality of projection surfaces based at least in part on the determined image segmentation type, and
• control the projection part to project the converted multi-sided image to the plurality of projection surfaces via the split prism.

A controlling method of an electronic device which includes a projection part, the projection part including a split prism for transmitting a part of light emitted from a light source in a front direction and reflecting a remaining part of light on at least one inclined surface in a lateral direction, the method comprising:

• converting an image corresponding to a received signal into a multi-sided image to be projected to a plurality of projection surfaces;
• and
• projecting the converted multi-sided image to the plurality of projection surfaces through the split prism,
• wherein the split prism includes:
• a hole positioned in its central region to transmit a part of light in the front direction, and
• a plurality of inclined surfaces positioned in a plurality of lateral direction of the hole for reflecting a part of the light in respective lateral directions.
