Electronic camera and image processing device

Abstract

An electronic camera comprises an imaging element, an image processing section, a face detecting section, a control section , a face image creating section, or a face recognition data creating section, and a recording section. The imaging element generates an imaging signal by photo-electrically converting the image of an object captured by an imaging optical system. The image processing section creates face registration image data from the image signal sent from the imaging element and creates through image data from the image signal. The face detecting section detects a face region on the imaging screen on the basis of the through image data. The control section adjusts the imaging parameter of the imaging optical system according to the detected position of the face region. The face image creating section cuts out the image of the face region to create face image data. The face recognition data creating section extracts a feature point of the face of the imaged person from the face region of the face registration image data and creates face recognition data according to the feature points. The recording section records the face recognition data or the face image data.

Description

Electronic camera and image processing device technical field The invention relates to an electronic camera and an image processing device with the function of recognizing the face of a person. Background technique Conventionally, there has been disclosed a technique of extracting feature points of a person's face from a photographed image of a person's face, and performing face recognition based on the degree of agreement between face recognition data on the person to be recognized and the above-mentioned feature points ( Refer to patent document 1). In the face recognition technology, it is necessary to register face recognition data in an electronic camera or the like in advance. In particular, in order to improve the accuracy of face recognition, a large amount of face recognition data is required, so it is necessary to generate face recognition data from photographed images of a plurality of frames. Furthermore, in registration photography for generating face recog...

Problems solved by technology

In addition, when a plurality of faces are detected in a plurality of shooting frames or when the total number of face recognition data used for face recognition determination is large, the computational load of the face recognition processing becomes extremely large.

In the above case, since the calculation time of the face recognition processing becomes longer, the comfortable shooting of the user is hindered, and the possibility of missing the opportunity to press the shutter becomes higher, and there is still room for improvement in the above points
