Methods and systems for colorizing an enhanced image during alert

Methods and systems for improving presentation of terrain/obstacle alerting information in a composite (synthetic and sensor) image. An exemplary system includes an imaging device that obtains image data for a region exterior to the vehicle, a processing system, and a display device. The processing system is in data communication with the display device and the imaging device. The processing system receives information from an alerting (e.g., a terrain awareness and warning) system and the obtained image data, colors, or makes transparent at least a portion of the obtained image data, if the received information indicates that an alert condition exists for the portion of the obtained image data, and generates a composite image comprising a previously generated synthetic image and the obtained image data with the enhanced portion. The display device displays the composite image. The obtained image data overlie the synthetic image.
