Abstract

A system and, related method, is disclosed for enabling Chroma key compositing using a smart device, wherein an image/video of a subject situated in front of a portable monochromatic background is captured, and simultaneously layered upon a different desired background replacement that will replace only the monochromatic background captured. The portable monochromatic background structure can be a three-dimensional lighting structure affixed with a plurality of lighting modules configured to ensure a uniform light distribution across the monochromatic background and separately to ensure a uniform light distribution on the subject during the image/video capture. Moreover, a software application on a smart device can act as a system platform that enables for automatic processing of pixel correction in the monochromatic background during the Chroma key process in real-time, and light adjustment of the lighting modules on a portable monochromatic background to correct any light imperfections that impede color neutrality on the background.

Claims (17)

1. A computer implemented system for Chroma key compositing and automated lighting adjustment, comprising:

a background structure, the background structure including a vertical surface, the surface including a monochromatic color or a distinguishing pattern;

a subject region disposed in front of the surface;

a plurality of light sources configured to illuminate the surface and a subject within the subject region; and

a processor configured to control the plurality of light sources and configured to identify each light source of the plurality of light sources as either illuminating the surface or the subject, wherein the processor is configured to dim or brighten one or more of the plurality of light sources to achieve a balanced lighting of the surface and the subject.

2. The system of claim 1 , wherein the processor is configured to identifying each light source by 1) receiving an identification from a user or 2) varying an output of each light source and detecting a change in lighting within a captured image.

3. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the surface obtained using the camera with a background image, video, or virtual environment to create a composite image, video or virtual environment including the subject, the background image video and/or a virtual environment.

4. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the surface obtained using the camera with a background image to create a composite image including the subject the background image including a video frame.

5. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the monochromatic area obtained using the camera with a geographical mapping of a location to determine what background image, video, animation, still photo, game, or virtual environment in which to create a composite image, video or virtual environment, including the subject, the background image video and/or a virtual environment and stream the resulting video.

6. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the monochromatic area obtained using the camera with a background image streamed from an eCommerce repository to create a composite image, video or virtual environment, including the subject, the background image video and/or a virtual environment and stream the resulting video.

7. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the monochromatic area obtained using the camera with an augmented reality-generated background image to create a composite image, video or virtual environment, including the subject, the background image video and/or a virtual environment.

8. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace multiple surfaces, each of the surfaces having different distinguishing characteristics, with background images to create multiple composite images within an image, video or virtual environment.

9. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the surface obtained using the camera with a background image and adjust visual characteristics of the background image to match lighting of the subject, to create a composite image, video or virtual environment, including the subject.

10. The system of claim 1 , further comprising: a computing device display, a camera; and a software application, the software application being stored on a non-transient media, the software application being configured to replace an image of the surface obtained using the camera with a background image, the background image being a still image, a part of a video or a view of a virtual environment, to create a composite image including the subject and the background image, and further configured to adjust these the composite image so that the background image and the subject have the similar dynamic ranges in pixel intensity.

11. The system of claim 1 , wherein the software application is further configured to retrieve the background image from a library of images, the library of images including still images, videos or virtual environments.

12. The system of claim 1 , wherein the software application is configured to control blurring of the background replacement image.

13. The system of claim 1 , wherein the software application is configured to automatically adjust brightness of the background image relative to a brightness of the subject by controlling the brightness of one or more of the plurality of light sources.
