Abstract
A method of calibrating an autofocus (AF) lighting device of a camera is disclosed. A reference image is captured with light projected from the AF lighting device, and a relative position of a central coordinate of the projected light with respect to a central coordinate of the reference image is stored. When operating the camera, the AF lighting device is activated to emit light after a shutter button of the camera is pressed halfway down, and a preview picture is displayed on a panel of the camera. A central position of the emitted light is then transposed toward a center of the panel according to the stored relative position.

A method of calibrating an autofocus lighting device of a camera, comprising:
- capturing a reference image with light projected from the autofocus lighting device;
- storing a relative position of a central coordinate of the projected light with respect to a central coordinate of the reference image;
- when operating the camera, activating the autofocus lighting device to emit light after a shutter button of the camera is pressed halfway down, and displaying a preview picture on a panel of the camera;
- and
- transporting a central position of the emitted light toward a center of the panel according to the stored relative position.
A method of calibrating an autofocus lighting device of a camera, comprising:
- capturing a reference image with light projected from the autofocus lighting device;
- and
- storing a relative position of a central coordinate of the projected light with respect to a central coordinate of the reference image;
- wherein the stored relative position is then accordingly utilized during camera operation to transport a central position of light emitted from the autofocus lighting device toward a center of a panel of the camera.
A method of calibrating an autofocus lighting device of a camera, in which a relative position of a central coordinate of projected light from the autofocus lighting device with respect to a central coordinate of a reference image is pre-stored, the method comprising:
- when operating the camera, activating the autofocus lighting device to emit light after a shutter button of the camera is pressed halfway down, and displaying a preview picture on a panel of the camera;
- and
- transporting a central position of the emitted light toward a center of the panel according to the stored relative position.
