First Claim
Patent Images
1. A method of simulating fill flash in a camera system comprising the steps of:
- determining distances from the camera to objects in a scene;
taking a photograph of the scene without using a flash; and
selectively adjusting the brightness of regions of the photograph based on the distance information.

Abstract
A digital camera simulates the use of fill flash. The camera takes a series of photographs of a scene at various focus distances. The photographs are stored, along with their corresponding focus distances. The photographs are analyzed to determine the distance to objects at various locations of the scene. Regions of a final photograph are selectively adjusted in brightness based on the distance information to simulate the effect that would have resulted had fill flash been used.
