Imaging means;
Face detection means for detecting face image data included in image data from the imaging means;
For each of a plurality of face image data detected by the face detecting means, a main face ratio calculating means for calculating a main face ratio representing the level of the main degree in the image data;
Based on the main face index of the plurality of face image data the calculated, from the plurality of face image data, a main face selection means the major degree to select the higher becomes the main face facial image data,
Identification means for executing identification processing on face image data to be the main face selected by the main face selection means ,
The main face selection means is configured such that when the identification by the identification means is successful, the calculated main face ratio of the face image data selected as the main face represents a higher main degree than when it fails. correction to the image pickup apparatus according to claim Rukoto.   The said main face rate calculation means calculates the said main face rate using at least the position in the said image data, and a magnitude | size of each of these several face image data. Imaging device. The face detecting means detects a position of the face image data in the image data;
The detected position of the face image data, the face image main face rate of the data, and the face of the storage means for storing the result of the identification processing of the image data, according to claim 1 or 2, characterized in that it further comprises The imaging device described in 1. The said main face selection means selects the said face image data of the main face ratio larger than a predetermined main face ratio as face image data used as the said main face, The one of Claims 1 thru | or 3 characterized by the above-mentioned. The imaging device according to item. The identification process A, the personal authentication and expression imaging apparatus according to any one of claims 1 to 4, characterized in that either recognition. A face detection step in which the face detection means detects face image data included in the image data from the imaging means;
A main face ratio calculating means for calculating a main face ratio representing the level of the main degree in the image data for each of a plurality of face image data detected in the face detection step;
A main face selection unit selects face image data to be a main face having a higher main degree from the plurality of face image data based on the main face ratio of the calculated plurality of face image data. A face selection process;
An identification step in which identification means performs identification processing on the face image data to be the main face selected in the main face selection step;
When the main face selection means succeeds in the identification in the identification step, the calculated main face ratio of the face image data selected as the main face represents a higher main degree than when it fails. And a correction step for correcting the image pickup apparatus. The program for making a computer perform each process of the control method of the imaging device of Claim 6 . A computer-readable storage medium storing a program for causing a computer to execute each step of the control method of the imaging apparatus according to claim 6 .
