Abstract
A method and image capture device for autofocus (AF) via a specific light signal, comprises the steps of: (a) emitting a light signal from an object in a scene to an image capture device, for example, a digital camera or a digital camcorder; (b) receiving and detecting the position of the light signal; (c) moving the lens of the image capture device to an acquired AF according to the position of the light signal; (d) setting the exposure and white balance data with weighting on the position of the light signal; and (e) capturing the image with the AF, exposure and white balance data. Therefore, even an unprofessional photographer can use such a device to focus on the object perfectly and rapidly.
