Image processing device and program

Abstract

The present invention provides an image processing device and program, capable of reliably picking-up field wherein most persons of a plurality of persons as picked-up bodies look same object in the image. The image processing device has a face detection section detecting faces of a plurality of persons included in the image according to image mode in the image signal; a sight line estimation section for estimating the sight line of the persons of faces detected by the face detection section; a distance calculation section respectively calculating distances of persons estimated by the sight line estimation section; and an interleaving determination section determining whether vision line of the persons is interleaved by using the estimated result and the calculated result.

Description

technical field [0001] The present invention relates to an image processing device and an image processing program for performing predetermined processing on image signals. Background technique [0002] Conventionally, in an image processing device such as a digital camera having an imaging function, a technique is known in which, when the subject is a person, the face of the person is detected, and the position of the detected face is focused. In addition, in recent years, there has been known a technology that automatically recognizes the timing when a subject person shows an expression suitable for photography, such as a smiling face, and takes a picture. [0003] A technique has been disclosed for extracting an image of the camera line of sight by judging the orientation of each person's face and the position of the black eyeball when a plurality of people are photographed as objects in such a situation (for example, refer to Patent Document 1). . Furthermore, there is...

Problems solved by technology

[0007] However, in the above-mentioned prior art, it is impossible to extract a scene in which a plurality of people stare at an object other than the image processing device at the same time.

Specifically, in the technique described in the above-mentioned Patent Document 1, only the camera sight lines of a plurality of persons are determined, and it is impossible to determine whether the sight lines of the plurality of persons are focused on objects other than the camera.

In addition, in the technique described in the above-mentioned Patent Document 2, only the face orientation and the gaze orientation of each person are estimated, and it is impossible to perform processing that takes into account the gaze relationship between multiple persons in the video.

[0008] Therefore, in the existing image processing device, in order to extract a scene in which a plurality of people as the subject stare at an object other than the image processing device at the same time, the photographer himself has to make a visual judgment. Difficult to extract scenes with many or distant subjects
