Abstract

An image processing apparatus includes a feature amount recognition unit that recognizes a feature amount of each of plural pieces of image data, and a processing reference extraction unit that extracts a processing reference for image correction to be made to the plural pieces of image data from the feature amount recognized by the feature amount recognition unit.

Claims

1-6. -6. (canceled)

7. An image processing apparatus comprising:

a feature amount recognition unit that recognizes a feature amount of each of a plurality of pieces of image data; and

a processing reference extraction unit that extracts a processing reference for image correction to be made to the plurality of pieces of image data from the feature amount recognized by the feature amount recognition unit

wherein the feature amount recognition unit recognizes an image quality containing at least any one of lightness, contrast, saturation, hue, and sharpness of each of the plurality of pieces of image data as the feature amount.

8-12. -12. (canceled)

13. An image processing apparatus comprising:

an input unit that inputs a plurality of digital images;

a feature amount recognition unit that recognizes a feature amount concerning an image quality of a main subject from each of the plurality of digital images input through the input unit; and

an image quality correction unit that makes a correction to the main subject of each of the plurality of digital images so that the image quality is unified from the feature amount concerning the image quality recognized by the feature amount recognition unit.

14. The image processing apparatus as claimed in claim 13,

wherein the feature amount concerning the image quality recognized by the feature amount recognition unit is at least any one of a feature amount concerning luminance of the main subject, a feature amount concerning saturation, a feature amount concerning color distribution, a feature amount concerning lightness, and a feature amount concerning sharpness.

15. The image processing apparatus as claimed in claim 13,

wherein the feature amount recognition unit further comprises a target value setting unit that sets a target value according to a statistical technique as for the image quality of the main subjects of the plurality of digital images, and

wherein the image quality correction unit makes a correction using the target value set by the target value setting unit.
