The emojivision app is able to make an iPhone create live updating emojis. The app was created by Gabriel O’Flaherty-Chan, and is available for free, however in-app purchases can be made. In-app purchases will unlock different emojis that a user's phone can access when it creates emoji images.
The emojivision app uses a person's camera to generate images that are comprised entirely of emojis. It is able to do this by reducing a camera, in order to add its color palette. The nearest color is then paired with a corresponding emoji, which is then used in the image. The app is able to run at a rate of 60 fps, which allows it to generate images in real-time.
The emojivision camera is able to be used to take selfies or standard photos.
