Abstract: An image evaluation device includes: an information acquiring unit to acquire, from an image containing at least one face, at least one type of information including at least the number of the at least one face and optionally including any of a size of the face, a position of the face in the image, an orientation of the face, a rotational angle of the face and a detection score of the face; and an individual evaluation value calculating unit to statistically calculate an individual evaluation value indicating a result of evaluation for each type of information based on the acquired information.

Abstract: An image evaluation apparatus and method capable of performing image evaluation more precisely using face information included in an image. An information obtaining unit obtains information with respect to at least one of the following face characteristics from an image including a face: face size, face position in the image, face orientation, face rotation angle, face-to-face positional relationship when a plurality of faces is included in the image, and face detection score. Then, an evaluation value calculation unit calculates an evaluation value representing an evaluation result of the image based on the information of the at least one of the face characteristics of face size, face position in the image, face orientation, face rotation angle, face-to-face positional relationship when a plurality of faces is included in the image, and face detection score obtained by the information obtaining unit.

Abstract: An information search system for search in plural images as content information is provided. An input interface inputs a first image. An dominant color extractor extracts an dominant color as attribute of the first image. A tag extractor extracts a tag or descriptor as meta information associated with the dominant color. A retriever retrieves a second image having the extracted tag or descriptor among the plural images. Furthermore, a display panel displays the second image. Also, a search refining selector selects image among plural sets of the second image to be output according to degree of relevancy of the second image with the first image. The relevancy for evaluation is relevancy of the dominant color.

Abstract: A method and apparatus capable of efficiently calculating evaluation values by reducing the processing time when performing image evaluation. When a processing target image for evaluation is specified, in order to calculate a comparative characteristic amount obtainable by comparing the processing target image with another image, a CPU determines whether or not the another image is tentatively stored in a cache. If the another image is stored in the cache, an individual evaluation value calculation unit calculates the comparative characteristic amount using the image stored in the cache, and calculates an individual evaluation value from the comparative characteristic amount. Then, an overall evaluation value calculation unit calculates an overall evaluation value based on a plurality of individual evaluation values, including the individual evaluation value calculated from the comparative characteristic amount.

Abstract: A method and apparatus capable of efficiently calculating evaluation values by reducing the processing time when performing image evaluation. When a processing target image for evaluation is specified, a CPU determines whether or not a processing result of a process performed when calculating a characteristic amount and/or evaluation value is tentatively stored in a cache. If the processing result is stored in the cache, an individual evaluation value calculation unit calculates a plurality of different types of individual evaluation values using the processing result stored in the cache. Then, an overall evaluation value calculation unit calculates an overall evaluation value based on the plurality of different types of individual evaluation values.
