Patent ID: 8238618

Claim:
An image-capturing apparatus for capturing an image using a solid-state image-capturing device, the image-capturing apparatus comprising: a face detector configured to detect a face of a human being based on an image signal in a period until an image signal obtained by image capturing is recorded on a recording medium; an expression evaluation section configured to evaluate the expression of the detected face and to compute an expression evaluation value indicating the degree to which the detected face is closer to a specific expression than to expressions other than the specific expression; and a notification section configured to output notification information corresponding to the computed expression evaluation value, wherein the expression evaluation section computes the expression evaluation value indicating the degree to which the detected face is closer to a first face group based on a plurality of pieces of face data associated with the specific expression than to a second face group based on a plurality of pieces of face data associated with the expressions other than the specific expression, and the expression evaluation section has pre-stored therein information on a determination axis obtained by performing linear discriminant analysis based on a first group of sample images of a plurality of faces in which each of the sample images has the specific expression and a second group of sample images of the plurality of faces in which each of the sample images has the expressions other than the specific expression, and computes the expression evaluation value based on the magnitude of projection components of a vector based on an image signal of the detected face with respect to a vector on the determination axis.
