Digital still camera with high-quality portrait mode
First Claim
1. A method for operating a camera, comprising the steps of waiting for an operator action, and responding to the operator action by:
- detecting information from a scene, the information comprising an image of radiation from the scene;
evaluating the detected information by;
identifying, in the image of radiation, a plurality of patterns each representative of a respective face;
then selecting a subset of the patterns equal in number to a specified number; and
then evaluating only the selected patterns in the subset relative to a human facial characteristic and a specified criteria;
wherein the detecting and evaluating steps are performed in a continuing manner until a point in time at which it is determined that the information from the scene includes information that is representative of the human facial characteristic and that satisfies the specified criteria; and
recording an image of the scene corresponding substantially to the point in time.

Abstract
A digital still camera (10) receives and digitizes visible radiation (17) and sound waves (32) from a scene (12). When an operator actuates a shutter release (46), the camera detects and evaluates digitized information (22, 38) from the scene in a continuing manner, until a point in time when information representative of a human facial characteristic satisfies a specified criteria set by the operator through use of switches (47, 48) and a display (51). The camera then records in a memory (59) a digital image of the scene, which corresponds to the point in time. The stored image is a high-quality image, which can avoid characteristics such as eyes that are closed or a mouth that is open.

3. The method for operating a camera, comprising the steps of:
-
responsive to an operator action, detecting visual information from a scene; evaluating the detected visual information relative to a human facial characteristic and a specified criteria; continuing the detecting and evaluating steps; responsive to the evaluating step determining that the visual information from the scene includes information that is representative of the human facial characteristic and that satisfies the specified criteria, recording an image of the scene; and detecting audible sound from the scene; wherein the evaluating step also evaluates the detected audible sound relative to the specified criteria; and wherein the recording step is responsive to the evaluating step determining both that the visual information from the scene includes information that is representative of the human facial characteristic and satisfies a first specified criteria, and that the detected audible sound satisfies a second specified criteria. - View Dependent Claims (4, 5)
