Abstract
An image pickup device displays, on a finder image area, an index mark indicating the wide angle side and the telephoto side of the zooming operations, an index mark indicating the zoom angle setting range in combination with the corresponding focal lengths, and an index mark indicating the current set position. When the photographer watches a desired position of the index mark, the viewpoint is detected by the viewpoint detecting device and the zooming operation is automatically conducted to the focal length corresponding to the viewpoint.
Claims40
An image processing device comprising:
- (A) display means for displaying, on a monitor image area, an index mark indicating a variable range of control values of a predetermined function;
- (B) viewpoint detecting means for detecting the position of the viewpoint of the operator in said image area;
- and
- (C) control means for, when said viewpoint is detected on said index mark by said viewpoint detecting means, converting the position information of the detected viewpoint on the index mark into driving information, and for driving said predetermined function according to the driving information regardless of a change of the viewpoint and without a manual command.
