About this app

This app enables users to stand in front of a solid-colored background—such as green, blue, or red—and automatically removes the selected color in real time, replacing it with a virtual background of their choice.

Special Feature:
Even without a green screen, users can still achieve a chroma key effect using any general background. Simply keep the camera still, tap the hotkey labeled "Chroma Key (General Background)", and wait for about 3–5 seconds. Once the virtual background appears on screen, you can capture and save your photo, share it with friends, or export the image with the background removed.

Pro Tip:
For best results, use bright, evenly lit solid colors—green or blue are highly recommended. Adequate lighting and minimizing shadows will significantly improve background removal accuracy.

Key Features
.Real-time chroma key (green screen) compositing
.Supports background removal even with general, non-solid backgrounds
.Quick lock/unlock for camera Auto-3A settings (AE: Auto Exposure, AF: Auto Focus, AWB: Auto White Balance)
.Hotkey support for switching between chroma key colors
.Automatically adjusts photo orientation for both portrait and landscape modes
.Instant photo preview after capture
.Easily change or import custom virtual backgrounds

Notes
.Works best with brightly colored backgrounds such as green, blue, or red
.If you notice performance issues (e.g., slow frame rate), try reducing the camera preview resolution
.Photo capture only; video recording is not yet supported

Does not work. You can choose whatever background inadequate you want but it will only use the stock China image. Will not save the image. It does a nice job it removing the ChromaKey background, but it is useless if you can't use your own background images and save the composites image. Look for something else.

Please use the button in the lower left corner, it can let you choose and change your own background. After that, take a picture. Hope you will like it again. ^_^

Really amazed by the level of chroma keying it does. I'm not sure if you've put an option to manually choose a different color apart from the primary colors provided, but if you've, it's not working for me. Also, it would be great if you could give an option to transform the background image.

Fun! not too picky with the colors and it kind of counts skin color and shadow as red Wich makes it able to do ghost effects but I can see this being annoying to some.
