IMAGE CAPTURING DEVICE, IMAGE CAPTURING METHOD AND CONTROLLING PROGRAM
First Claim
1. An image capturing device for obtaining image data by photo-electrically converting a subject image focused on an imaging element through an imaging optical system, and storing said image data in a storing section, said image capturing device comprising:
- a face detecting section for detecting a face of said subject based on said image data;
a face center detecting section for detecting a central coordinate of said face in a shooting screen based on said image data of said detected face;
a face centroid detecting section for detecting a centroid coordinate which is a center of all faces based on said central coordinate of each face detected by said face center detecting section when plural faces are detected by said face detecting section;
a judging section for judging whether said central coordinate of each face is inside said shooting screen or not and whether said centroid coordinate is inside a predetermined determination area provided in said shooting screen or not; and
a controlling section for permitting image capturing when said judging section judges that said central coordinate is inside said shooting screen and said centroid coordinate is inside said determination area.

Abstract
When a shutter button is half-pressed, image signal of a field image is read from a CCD, and is converted into image data of digital. For example three faces are detected based on the image data, and a face central coordinate of each face is extracted and a face centroid coordinate of the faces is calculated based on the face central coordinates. When all of the face central coordinates are inside the shooting screen and the face centroid coordinates is inside the determination area, the digital camera induces the user to perform image capturing, with use of an LED and audio guidance. When the shutter button is full-pressed, image signal of a frame image is read from a CCD, and is converted into image data of digital. After various image processing, the image data is stored in a memory card.

12. An image capturing device for obtaining image data by photo-electrically converting a subject image focused on an imaging element through an imaging optical system, and storing said image data in a storing section, said image capturing device comprising:
-
a segment designating section for virtually dividing a shooting screen into plural segments and designating a segment for displaying a face of said subject; a number and interval setting section for setting the number of image capturing and a capturing interval; a self-timer for starting time measurement in response to shutter release operation and permitting image capturing after a predetermined time is passed; a face detecting section for detecting a face of said subject based on said image data after said self-timer starts time measurement; a face center detecting section for detecting a central coordinate of said face in a shooting screen based on said image data of said detected face; a face centroid detecting section for detecting a centroid coordinate which is a center of all faces based on said central coordinate of each face detected by said face center detecting section when plural faces are detected by said face detecting section; a judging section for judging whether said central coordinate of each face is inside said designated segment or not and whether said centroid coordinate is inside a predetermined determination area provided in said designated segment or not; an exposure calculating section for calculating a correct exposure based on said image data of said face; a focus position detecting section for detecting a focus position based on said image data of said face; and a controlling section for locking said correct exposure and said focus position and performing image capturing with said number of image capturing and said capturing interval set by said number and interval setting section, when said judging section judges that said central coordinate of each face is inside said designated segment and said centroid coordinate is inside said determination area and after said self-timer measures said predetermined time. - View Dependent Claims (13)
