Claims

Storage means for storing a first feature amount indicating a feature of the subject;
An imaging means for photoelectrically converting a subject image formed by a photographing lens to obtain a photographed image;
Extraction means for extracting a feature amount of a subject from a captured image obtained by the imaging means;
The extraction means extracts from the captured image from which at least one of the first feature values has been extracted or from other information associated with the captured image from which at least one of the first feature values has been extracted. An imaging apparatus comprising: an adding unit that stores a new second feature quantity in the storage unit in association with the extracted first feature quantity.

The adding unit adds information on the subject corresponding to the first feature amount to the captured image obtained by the imaging unit when at least one of the first feature amount is extracted by the extracting unit. The imaging apparatus according to claim 1, wherein:

The adding means is obtained by the imaging means even if the first feature quantity is not extracted when at least one of the second feature quantities stored by the storage means is extracted by the extraction means. The imaging apparatus according to claim 2, wherein information regarding a subject corresponding to the first feature amount is added to the captured image.

The adding means may be associated with a photographed image from which at least one of the second feature quantities has been extracted by the extracting means or to a photographed image from which at least one of the second feature quantities has been extracted. When a new third feature quantity is extracted from the information of the first feature quantity, the third feature quantity is associated with the extracted first feature quantity even if the first feature quantity is not extracted. The image pickup apparatus according to claim 1, wherein the image pickup apparatus is stored in a means.

Comprising face detection means for detecting a face area of a subject from an image obtained by the imaging means;
The imaging apparatus according to claim 1, wherein the extraction unit extracts a feature amount of a subject from the face area detected by the face detection unit.

Character information detection means for detecting a character pattern indicating subject information from the image obtained by the imaging means is provided, and the extraction means extracts a feature amount of the subject from the character pattern detected by the face detection means. The imaging apparatus according to claim 1.

Conversion means for converting the character information detected by the character information detection means into text data;
The imaging apparatus according to claim 6, wherein the extraction unit extracts text data converted by the conversion unit as a feature amount.

Voice receiving means for receiving voice;
The imaging apparatus according to claim 1, wherein the extraction unit extracts a feature amount from the voice received by the voice reception unit.

A communication means for communicating with the outside through a communication line;
Comprising subject information receiving means for receiving information about the subject;
The imaging apparatus according to claim 1, wherein the first storage unit stores a feature amount based on information received by the subject information reception unit.

The imaging apparatus according to claim 9, wherein the information received by the subject information receiving unit is text data.

An extraction step of extracting the feature amount of the subject from the captured image obtained by the imaging means;
Extracted from the captured image from which at least one of the first feature values indicating the characteristics of the subject is extracted by the extraction step or from information associated with the captured image from which at least one of the first feature values is extracted. An imaging method comprising: an adding step of storing the new second feature amount in association with the extracted first feature amount in a storage unit.
