Information terminal, information control method for an information terminal, and information control program

摘要

To make it possible to significantly reduce a burden on a user at a time of a classification of image files added or updated, for example, and thus facilitate association with other content data. An image detector/register (20) detects an image file that is unregistered or updated, and structures and manages a list of the image files. A face rectangular detector (21) detects a face rectangle in the image files detected, associates information on the face rectangle with the image file, and stores the information. A similar face classification section (22) calculates an amount of feature of the face rectangle, compares the amount of feature calculated with amounts of feature of different face rectangles already calculated and classified into groups, calculates a similarity between the face rectangle and the face rectangles of the different face rectangles in the respective groups, and classifies and manages the face rectangles in accordance with a result of the similarity calculation. A similar face display section (23) displays at least one image file including the face rectangle classified into the same group on a display screen.

1. An information terminal, comprising:
circuitry configured to
detect an image file;detect a face image included in an image of the detected image file;calculate an amount of feature of the detected face image;compare the amount of feature calculated with amounts of feature of different face images which are already calculated and classified into groups;calculate similarity values between the detected face image and the different face images in the respective groups;determine average similarity values of the respective groups, each one of the average similarity values representing an average value of the similarity values associated with a corresponding one of the groups;determine minimum similarity values of the respective groups, each one of the minimum similarity values representing a minimum value of the similarity values associated with a corresponding one of the groups;classify and manage the detected face image in a first one of the groups corresponding to an average similarity value that is the highest among the average similarity values and that is greater than a first threshold;associate the face images in a second one of the groups with the first one of the groups when the average similarity value of the second one of the groups is greater than the first threshold and the minimum similarity value of the second one of the groups is greater than a second threshold; anddisplay at least one image file, which includes a face image classified as the first one of the groups, on a display screen based on a result of the classification of the detected face image.
