Embodiment Construction

[0040]Hereinafter, preferred embodiments will be described with reference to the drawings, using a camera to which the image retrieval device of the present invention is applied. A camera according to a preferred embodiment of the present invention is a digital camera, and has an imaging unit that converts an image of a subject into image data, and uses the converted image data to monitor The subject image is displayed in a live view. The photographer determines the composition and shutter timing by observing the live view display. At the time of the release operation, image data is recorded to the recording medium. When the reproduction mode is selected, the image data recorded on the recording medium can be reproduced and displayed on the display unit.

[0041] figure 1 It is a block diagram showing the configuration of a camera according to one embodiment of the present invention. A control unit (CPU: Central Processing Unit, central processing unit) 11 operates in acco...

Abstract

PROBLEM TO BE SOLVED: To provide an image retrieval device, an image retrieval method, and a camera capable of extracting appropriate number of images even if the number of images for searching is in a wide range.SOLUTION: An image retrieval device for selecting a similar image which is an image including a subject similar to a subject in a retrieval reference image comprises: a similarity determination part 11a2 for determining a degree of similarity P, which defines similarity between the reference image displayed on a sub display 62 and individual retrieved images; and an image selector 11a3 for setting a selection level with a selection cursor 72 for selecting a similar image and selecting a similar image 65 having a higher similarity level than the set selection level out of the retrieved images whose similarities have been determined. The image selector 11a3 sets the selection level high if a number of the retrieved images is high and sets the selection level low if the number of the retrieved images is low.

Description

technical field [0001] The present invention relates to an image retrieval device, an image retrieval method, and a camera, and more particularly to an image retrieval device, an image retrieval method, and a camera that retrieve similar images from a plurality of images and display the retrieval results. Background technique [0002] In recent years, techniques for analyzing photographed images and specifying subjects such as people, buildings, mountains, and seas have been developed, and automatic image retrieval using this technique has been put into practical use. In particular, the technology of recognizing a specific person from a facial image has been significantly advanced (for example, Patent Document 1, Patent Document 2, etc.). [0003] In addition, various techniques related to similar image retrieval of so-called similar images that search for subject types and scene contents of photographed images, or other images similar to photographed persons have also been ...
