Samsung patents projector tech that blends images with the wall behind them

Patent drawing
Patent drawing from the official filing.

Samsung has been granted a patent for a projector system that uses a built-in camera to photograph the projected image and the wall behind it. The device adjusts the colors and brightness of the outer parts of the projection to match the surrounding wall, making the image blend in more naturally.

Why it mattersThis could make projected images look less like a bright rectangle on a wall and more like they are part of the room, improving the viewing experience for home theaters or office presentations.

In the filing’s own words

An electronic apparatus is provided. The electronic apparatus includes: a projector configured to project an image with a specified resolution, a camera, and at least one processor, comprising processing circuitry, connected to the projector and the camera and configured to control the electronic apparatus, wherein at least one processor, individually and/or collectively, is configured to: perform keystone correction for a first image, control the projector to project an image of the specified resolution in which the keystone-corrected first image is included in one area and a second image is included in a remaining area to a projection area, obtain a captured image by photographing the projection area and an external area of the projection area through the camera, adjust a pixel value of the second image based on first pixel information corresponding to the remaining area in the captured image and second pixel information corresponding to the external area of the projection area, and control the projector to project an image of the specified resolution in which the keystone-corrected first image is included in the one area and the second image with the adjusted pixel value is included in the remaining area to the projection area.

What exactly they claim (claim 1)

1. An electronic apparatus comprising: a projector configured to project an image with a specified resolution; a camera; and at least one processor, comprising processing circuitry, connected to the projector and the camera; a memory storing instructions which, when executed individually and/or collectively by the at least one processor, controls the electronic apparatus to: perform keystone correction for a first image to generate a keystone-corrected first image; control the projector to project to a projection area an image of the specified resolution in which the keystone-corrected first image is included in one area in the projection area and a second image is included in a remaining area in the projection area; obtain a captured image by photographing the projection area and an external area outside of the projection area through the camera; adjust a pixel value of the second image in the remaining area based on first pixel information corresponding to the remaining area in the captured image and second pixel information corresponding to the external area outside of the projection area; and control the projector to project an image of the specified resolution in which the keystone-corrected first image is included in the one area in the projection area and the second image with the adjusted pixel value is included in the remaining area in the projection area.
