IMAGING APPARATUS, IMAGING METHOD, AND PROGRAM
An imaging apparatus includes: recording memory ( 113 ) for storing an image of a subject; detection unit ( 105 b ) that detects the faces of people from a signal realized by imaging of an image of a subject; evaluation unit ( 105 c ) that, when detection unit ( 105 b ) detects faces of a plurality of people, evaluates each of the expressions of the faces of a plurality of people that were detected and computes a plurality of expression values in which the evaluated expressions are each converted to a numerical value; and control unit ( 110 ) that computes a deciding expression value from a plurality of expression values for determining whether the image of the subject is to be stored or not and that causes storage of the image of the subject in recording memory ( 113 ) when the deciding expression value is equal to or greater than a predetermined threshold value.
1 . An imaging apparatus comprising:
a memory for storing an image of a subject;
a detection unit that detects the face of a person from a signal realized by capturing said image of the subject;
an evaluation unit that, when the faces of a plurality of people are detected by said detection unit, evaluates each of the expressions of the faces of said plurality of people that were detected and computes a plurality of expression values in which each of said evaluated expressions are converted to numerical values; and
a control unit that computes a deciding expression value based on said plurality of expression values for determining whether said image of the subject is to be stored or not, and when said deciding expression value is equal to or greater than a predetermined threshold value, causes said image of the subject to be stored in said memory.
2 . The imaging apparatus as set forth in claim 1 , wherein said control unit takes the highest expression value among said plurality of expression values as said deciding expression value.
3 . The imaging apparatus as set forth in claim 1 , wherein said control unit takes the lowest expression value among said plurality of expression values as said deciding expression value.
4 . The imaging apparatus as set forth in claim 1 , wherein said control unit takes the average value of said plurality of expression values as said deciding expression value.
5 . The imaging apparatus as set forth in claim 1 , wherein said control unit takes as said deciding expression value the average value of expression values that remain after excluding at least one expression value from said plurality of expression values.

8 . An imaging method in an imaging apparatus that includes a memory for storing an image of a subject, said imaging method comprising processes of:
detecting the face of person from a signal realized by capturing said image of the subject;
when faces of a plurality of people are detected, evaluating the expressions of each of the faces of said plurality of people that were detected and computing a plurality of expression values in which said expressions that were evaluated are each converted to a numerical value; and
computing a deciding expression value based on said plurality of expression values to determine whether said image of the subject is to be stored or not, and when said deciding expression value is equal to or greater than a predetermined threshold value, storing said image of the subject in said memory.
9 . The imaging method as set forth in claim 8 , further comprising a process wherein the highest expression value among said plurality of expression values is taken as said deciding expression value.
10 . The imaging method as set forth in claim 8 , further comprising a process wherein the lowest expression value among said plurality of expression values is taken as said deciding expression value.
11 . The imaging method as set forth in claim 8 , further comprising a process wherein the average value of said plurality of expression values is taken as said deciding expression value.
12 . The imaging method as set forth in claim 8 , further comprising a process wherein the average value of expression values that remain after excluding at least one expression value from said plurality of expression values is taken as said deciding expression value.
13 - 21 . (canceled)
22 . A computer readable recording medium in which a program is recorded, said program causing an imaging apparatus having a memory for storing an image of a subject to execute functions of:
detecting the face of a person from a signal realized by capturing said image of the subject;
when faces of a plurality of people are detected, evaluating the expressions of each of the faces of said plurality of people that were detected and computing a plurality of expression values in which said expressions that were evaluated are each converted to a numerical value; and
computing a deciding expression value from said plurality of expression values to determine whether said image of the subject is to be stored or not, and when said deciding expression value is equal to or greater than a predetermined threshold value, storing said image of the subject in said memory.
23 . The computer readable recording medium as set forth in claim 22 , wherein said program further causes the execution of a function wherein the highest expression value among said plurality of expression values is taken as said deciding expression value.
24 . The computer readable recording medium as set forth in claim 22 , wherein said program further causes execution of a function wherein the lowest expression value among said plurality of expression values is taken as said deciding expression value.
25 . The computer readable recording medium as set forth in claim 22 , wherein said program further causes the execution of a function wherein the average value of said plurality of expression values is taken as said deciding expression value.
26 . The computer readable recording medium as set forth in claim 22 , wherein said program further causes the execution of a function wherein the average value of expression values that remain after excluding at least one expression value from said plurality of expression values is taken as said deciding expression value.
