According to one embodiment, an environment evaluation apparatus includes a generation unit, a storage and a comparison unit. The generation unit generates a feeling index representing a feeling toward a target image to be processed. The storage stores a plurality of comparative images and corresponding comparative feeling indexes, according to each of feeling categories. The comparison unit extracts, as a similar image, at least one of the comparative images corresponding to at least one of the comparative feeling indexes having a degree of similarity to the feeling index not less than a threshold value, by comparing the feeling index with the comparative feeling indexes. |

1. An environment evaluation apparatus, comprising:
a generation unit configured to generate a feeling index representing a feeling toward a target image to be processed, the feeling index including at least one of a first index, a second index and a third index, the first index being obtained by performing frequency analysis on the target image, the second index being obtained by performing histogram analysis on the target image, the third index being a characteristic quantity of a group of pixels relating to at least one of a color and a luminance from a partial region of the target image; a storage configured to store a plurality of comparative images and corresponding comparative feeling indexes, according to each of feeling categories, the comparative images being images with which the target image is to be compared and being classified into the feeling categories using the comparative feeling indexes, the comparative feeling indexes representing feelings toward the comparative images, the feeling categories being categories based on feelings toward images; and a comparison unit configured to extract, as a similar image, at least one of the comparative images corresponding to at least one of the comparative feeling indexes having a degree of similarity to the feeling index not less than a threshold value, by comparing the feeling index with the comparative feeling indexes. |
