Abstract:
1. A face image detecting apparatus for detecting a face-image portion contained in each image of a plurality of frames of images represented by continuously applied image data, comprising: an image sensing device for sensing the image of a subject continuously and outputting image data representing the image of the subject; a detecting device for detecting a value of face likeliness and position of a face-image portion contained in the image represented by the image data that has been output from said image sensing device; a displacement-amount measuring device for measuring amount of displacement between the position of the face-image portion detected by said detecting device and position of a face-image portion detected by the detecting device in a preceding frame of an image; a displacement-amount determination device for determining whether the amount of displacement measured by said displacement-amount measuring device is less than a threshold value; a face-likeliness determination device for determining whether the value of face likeliness detected by said detecting device is equal to or greater than a prescribed threshold value; a deciding device for deciding that a person having a face-image portion at the position detected by said detecting device and a person having a face-image portion at the position detected in the preceding frame of the image are the same in response to a determination by said displacement-amount determination device that the amount of displacement is less than the threshold value and, moreover, a determination by said face-likeliness determination device that the value of face likeliness is equal to or greater than the threshold value; and a focusing/luminance-adjusting device, wherein
