Abstract: A method of operating an optical system is described. An image is detected. A digital image signal based on a spatially varying luminance level of the detected image is received. Horizon data, separate from the digital image signal, indicating the position of a horizon where a sky is adjacent the horizon, is received. The position of the horizon is determined based on the received horizon data. A fused image signal is provided based on the received digital image signal and the determined position of the horizon where a sky region indicative of the sky is provided with an enhanced color fused with the varying luminance level of the detected image. A full color display displays a fused image based on the fused image signal. A corresponding optical system is also described.
