Imaging apparatus including an auto focusing function
First Claim
1. An imaging apparatus comprising:
- a photographic optical system for projecting an image of a subject;
an imaging device for outputting the projected image of the subject by converting the projected image of the subject into an image signal;
a first auto focusing device for carrying out a first auto focusing operation corresponding to a distance value obtained by measuring a distance to said subject;
a second auto focusing device for carrying out a second auto focusing operation corresponding to an evaluation value obtained by evaluating the image signal output by said imaging device;
a control device for controlling said first auto focusing operation and said second auto focusing operation;
a starting signal inputting device for inputting a command for starting a focusing operation; and
a photographing signal inputting device for inputting a command for performing a photographing operation;
wherein said control device starts said first auto focusing operation when said starting signal inputting device inputs said command for starting and controls said first auto focusing operation and said second auto focusing operation corresponding to an elapsed time from the inputting of the command for starting, a condition of inputting said command for starting into said starting signal inputting device and a condition of inputting said command for performing into said photographing signal inputting device at a time after the command for starting is inputted.

Abstract
An AF controlling unit (83) starts an outside light AF operation controlled by an outside AF unit (81) by a half-pressing of a shutter release button (61), and a change over between the outside AF operation and a CCDAF operation controlled by a CCDAF unit (82) is controlled corresponding to an elapsed time t (timer 84) from a starting of the operation of the outside light AF operation and a pressing condition (a detection of the half-pressing by a half-pressed detecting unit (62), the detection of a full-pressing by a full-pressed detecting unit (63) or a press-in releasing) of a shutter release button (61) after the starting of the outside light AF operation controlled by the outside AF unit (81) by the half-pressing of the shutter release button (61).
