ABSTRACT:
The focusing lens serves to focus an image on a CCD. The image is displayed in a view finder through a different optical axis. A focus evaluation area determining circuit establishes a plurality of preset focus evaluation areas for the respective object distances on the basis of the axis offset between the optical axes of the focusing lens and the view finder. The corresponding preset object distance is compared with the object distance measured for the focus evaluation area in an object detection circuit. The result of the comparison allows the detection of an object specified in the view finder.
