ABSTRACT:
An exposure control method adjusts an exposure setting used for capturing an image including a foreground object and a background. The foreground object is extracted from the image by an object detection procedure. If the area of the foreground object is greater than a predetermined area value, the brightness of both the foreground object and the background is analyzed. On the contrary, if the area of the foreground object is not greater than the predetermined area value, only the brightness of the background is analyzed. The exposure setting is adjusted according to the analysis result. Accordingly, greater brightness stability is provided during the capture of the following images.
