The Pixelated World is a project that detects colors in real-time and transforms images into a pixelated format. The size of the pixels changes into five different scales depending on the surrounding brightness. The goal of this project was to simplify the way we perceive the world to an extreme level, providing a new visual experience and shifting our perspective. The core principle of this system is adjusting pixel size according to ambient brightness. When the surroundings become brighter, the pixels shrink, and when it gets darker, the pixels enlarge. This structure allows users to experience light and darkness in a simplified form. Additionally, colors are randomly combined every moment, creating an effect where the environment appears both simplified and vibrant at the same time. Through this, users can engage in a visual experience that reinterprets the familiar world in a new way.
