Abstract
An image pickup apparatus, which includes an eye point sensor for detecting an eye point in a frame, a calculation circuit for calculating average coordinates of the eye point in the frame detected by the eye point sensor, a setting circuit for setting a distance measurement frame at the average coordinates output from the calculation circuit, and a control circuit for controlling the size of the distance measurement frame according to the focal length, is disclosed. An image pickup apparatus, which includes a focus calculation circuit for detecting a focus state by detecting the dispersion range of an eye point, is also disclosed.
Claims16
An image pickup apparatus for performing a focus adjustment operation according to a signal within a focus detecting frame set on an image pickup frame, comprising:
- (A) detection means for detecting position coordinates of an eye point of a photographer in the image pickup frame;
- (B) calculation means for calculating an average value of the position coordinates of the eye point detected by said detection means;
- and
- (C) setting means for setting a position of the focus detecting frame in the image pickup frame according to said average value output from said calculation means.
An image pickup apparatus for performing a focus operation of an optical means according to a signal within a focus detecting frame set on an image pickup frame, comprising:
- (A) detection means for detecting position coordinates of an eye point of a photographer in the image pickup frame;
- (B) calculation means for calculating an average value of the position coordinates of the eye point detected by said detection means;
- (C) setting means for setting a position of the focus detecting frame in the image pickup frame according to said average value output from said calculation means;
- and
- (D) control means for changing a size of the focus detecting frame set by said setting means according to a state of said optical means.
An image pickup apparatus for performing an adjustment operation according to a signal within an image detecting frame set on an image pickup frame, comprising:
- (A) detection means for detecting position coordinates of any eye point of an operator in the image pickup frame;
- (B) calculation means for calculating an average value of the position coordinates of the eye point detected by said detection means;
- and
- (C) setting means for setting a position of the image detecting frame in the image pickup frame according to said average value output from said calculation means.
