## Abstract

The present invention is to provide a system, a method, and a program for identifying a person depicted in a portrait. The system for identifying a person depicted in a portrait 1 receives input of portrait data of the portrait, stores different individual data depending on a plurality of persons, extracts a feature point of the received portrait by image analysis, checks the extracted feature point against the individual data, identifies a person depicted in the portrait from the check result, and displays the identification result together with a probability corresponding to an identical level.

## Claims

### Claim 1

A system for identifying a person depicted in a portrait, comprising:
a receiving unit that receives input of portrait data of the portrait;
a memory unit that stores different individual data depending on a plurality of persons;
an extraction unit that extracts a feature point of the received portrait by image analysis;
a check unit that checks the extracted feature point against the individual data;
an identification unit that identifies a person depicted in the portrait from the check result; and
a display unit that displays the identification result together with a probability corresponding to an identical level,
wherein the different individual data are different portrait data and different taken image data, and the check unit changes the check procedure based on whether data against which the extracted feature point is to be checked are the different portrait data or the different taken image data.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the different individual data are different portrait data.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the different individual data are different taken image data.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the extraction unit extracts the feature amount of each part of the received portrait data, and the check unit checks the extracted feature amount of the each part against the same each part of the stored individual data.

### Claim 5 (depends on 5)

The system according to claim 5, wherein the display unit displays a probability corresponding to the identical level of the each part.

### Claim 6 (depends on 1)

The system according to claim 1, wherein the display unit displays probabilities corresponding to the respective identical levels together if the number of the identified persons is two or more.

### Claim 7 (depends on 1)

The system according to claim 1, wherein the display unit displays a reason why the person is identified.

### Claim 8 (depends on 1)

The system according to claim 1, wherein the display unit displays property information on the identified person.

### Claim 9

A method for identifying a person depicted in a portrait, comprising:
receiving input of portrait data of the portrait;
storing different individual data depending on a plurality of persons;
extracting a feature point of the received portrait by image analysis;
checking the extracted feature point against the individual data;
identifying a person depicted in the portrait from the check result; and
displaying the identification result together with a probability corresponding to an identical level,
wherein the different individual data are different portrait data and different taken image data, and the check procedure is changed based on whether data against which the extracted feature point is to be checked are the different portrait data or the different taken image data.

### Claim 10

A computer program product for use in a system for identifying a person depicted in a portrait, comprising a non-transitory computer usable medium having a set of instructions physically embodied therein, the set of instructions including computer readable program code, which when executed by the system causes the information processing unit to:
receive input of portrait data of the portrait;
store different individual data depending on a plurality of persons;
extract a feature point of the received portrait by image analysis;
check the extracted feature point against the individual data;
identify a person depicted in the portrait from the check result; and
display the identification result together with a probability corresponding to an identical level,
wherein the different individual data are different portrait data and different taken image data, and the check procedure is changed based on whether data against which the extracted feature point is to be checked are the different portrait data or the different taken image data.
