Document Type and Number:
WIPO Patent Application WO/2024/053756
Kind Code:
A1
Abstract:
The present invention is characterized by comprising: an input unit including a camera which obtains ambient image information and a microphone which collects ambient sound signals including voices; a sensing unit including an illuminance sensor which detects ambient illuminance; an output unit including an image output unit which outputs the image information and a light source unit which emits light; a drive unit capable of changing the horizontal direction and vertical direction the output unit is facing, as well as the height of the output unit; and a control unit which determines whether an image projection request is made on the basis of the information sensed through the input unit, controls the drive unit so that, when a specific area in the room is designated as an image projection area according to the determination result, the output unit is facing the designated image projection area, detects the illuminance of the image projection area and determines the size of an image to be projected according to the detected illuminance when the output unit is facing the image projection area, and controls the output unit so that the image is projected according to the determined image size.
