In general, the present disclosure is directed to an artificial window system that can simulate the user experience of a traditional window in environments where exterior walls are unavailable or other constraints make traditional windows impractical. In an embodiment, an artificial window consistent with the present disclosure includes a window panel, a panel driver, and a camera device. The camera device captures a plurality of image frames representative of an outdoor environment and provides the same to the panel driver. A controller of the panel driver sends the image frames as a video signal to cause the window panel to visually output the same. The window panel may further include light panels, and the controller may extract light characteristics from the captured plurality of image frames to send signals to the light panels to cause the light panels to mimic outdoor lighting conditions.
