Abstract

It is an object of the present invention to provide an image processing device capable of capturing an image of various objects and common scenes with ideal compositions and attractive compositions. The image processing device predicts an attention region 52 for a through image 51, based on a saliency map S having a plurality of feature quantity maps Fc, Fh, and Fs integrated therein (steps Sa to Sc). The image processing device extracts line components (e.g., edge SL) of an edge image 53 (step Se, Sf) corresponding to the through image 51. The image processing device uses the attention region 52, the line components (e.g., edge component SL), or the like and identifies, from among a plurality of model composition suggestions, a model composition suggestion that resembles the through image 51 in regard to a state of positioning of the principal object.

Claims

1. An image processing device comprising:

a prediction section that predicts an attention region for an input image including a principal object, based on a plurality of feature quantities extracted from the input image; and

an identification section that identifies, using the attention region thus predicted by the prediction section, a model composition suggestion that resembles the input image in regard to a state of positioning of the principal object, from among a plurality of model composition suggestions.

2. An image processing device according to claim 1, wherein

the identification section identifies a composition suggestion that resembles the input image in regard to a state of positioning of the principal object using line components of an edge image corresponding to the input image, in addition to the attention region.

3. An image processing device according to claim 1, further comprising an exhibition section that exhibits the model composition suggestion identified by the identification section.

4. An image processing device according to claim 3, further comprising an evaluation section that performs evaluation on the model composition suggestion thus identified by the identification section,

wherein the exhibition section further exhibits an evaluation result from the evaluation section.

5. An image processing device according to claim 3, further comprising a generation section that generates guide information that leads to a predetermined composition, based on the model composition suggestion thus identified by the identification section,

wherein the exhibition section further exhibits the guide information generated by the generation section.

6. An image processing method comprising:

a prediction step of predicting an attention region for an input image including a principal object, based on a plurality of feature quantities extracted from the input image; and

an identification step of identifying, using the attention region predicted by the processing of the prediction step, a model composition suggestion that resembles the input image in regard to positioning of the principal object, from among a plurality of model composition suggestions.
