Abstract:
In an AF camera having a two-stage capture button or a three-stage capture button, a timing control module or algorithm is used to control the type of image a user can obtain after the user presses and releases the capture button. The timing control allows the user to capture an image of the scene substantially as presented on the viewfinder when the automatic focusing algorithm carries out its focusing function, or to capture an image of a recomposed scene after the focusing function is completed. If the user releases the capture button before the automatic focusing algorithm finishes its focusing function, the image obtained is the image focused at the hyperfocal distance.
