Abstract
A device includes a projector to project an image onto a surface. The device also includes a camera to capture a picture of the image, while it is being projected onto the surface, and a portion of an area surrounding the projected image. The device identifies a lightest portion in the projected image. The device adjusts a setting of the projector based on a comparison of an intensity of the identified lightest portion to an intensity of the portion of the area surrounding the projected image.
Claims19
A method comprising:
- projecting, via a projector, an image onto a surface;
- and
- using a picture of the projected image and a portion of an area surrounding the projected image to automatically alter a setting of the projector, the using the picture including:
- identifying a lightest portion in the projected image, and
- comparing an intensity of the identified lightest portion to an intensity of the portion of the area surrounding the projected image.
A device comprising:
- a projector to project an image onto a surface;
- a camera to capture a picture of the image while it is being projected onto the surface;
- memory to store instructions;
- and
- a processor to execute the instructions to:
- receive the picture,
- compare an intensity of a first portion of the picture to an intensity of a second portion of the picture, and
- adjust a setting of the projector when the intensity of the first portion is within a threshold of the intensity of the second portion.
A computer-readable medium to store instructions that, when executed by at least one processor, cause the at least one processor to perform a method comprising:
- receiving a picture of an image projected onto a surface by a projector and a portion of an area surrounding the projected image;
- and
- adjusting a setting of the projector based on the received picture, the adjusting including:
- identifying a lightest portion in the projected image, and
- comparing an intensity of the identified lightest portion to an intensity of the portion of the area surrounding the projected image.
A method comprising:
- projecting, via a projector device, an image onto a surface;
- capturing, via the projector device, a picture of the projected image;
- and
- adjusting, via the projector device, a setting of the projector device based on a content of the captured picture, the adjusting including:
- comparing an intensity of a first portion of the captured picture to an intensity of a second portion of the captured picture, and
- adjusting an intensity output of the projector when the intensity of the first portion substantially matches the intensity of the second portion.
A device comprising:
- means for projecting an image onto a surface;
- means for capturing a picture of the projected image and a portion of an area surrounding the projected image;
- and
- means for adjusting an intensity of at least one image projected by the means for projecting based on identifying a lightest portion in the projected image and comparing an intensity of the identified lightest portion to an intensity of the portion of the area surrounding the projected image.
