Abstract
A detection system for an image capture device includes an image detecting unit, a calculation unit, a selection unit and a switching unit. The image detecting unit provides a plurality of focus modes suitable for different ambient light conditions, and acquires image parameters. The calculation unit determines exposure time suitable for the current ambient light conditions based on the acquired parameters. The selection unit selects a suitable detection mode based on the determined exposure time. The switching unit switches the image capture device to the selected suitable detection mode.
