IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND PROGRAM

摘要

The present invention has an object to enable white balance correction appropriate to an image photographed with strobe light-emitting. An image processing apparatus includes: a first correcting unit that corrects image data photographed with strobe light-emitting using a first WEB correction value corresponding to environmental light, and generates a first WEB correction image; a second correcting unit that corrects the image data photographed with strobe light-emitting using a second WEB correction value corresponding to strobe light, and generates a second WEB correction image; a combining ratio calculating unit that obtains a combining ratio of the first and second WEB correction images based on information on a distance to an object photographed with strobe light-emitting and distribution characteristics of the strobe light; and a combining unit that combines the first and second WEB correction images based on the combining ratio.

主权项

1. An image processing apparatus comprising:
a first correcting unit that corrects data on a strobe light-emission image photographed with strobe light-emitting, using a first white balance correction value corresponding to environmental light, and generates first white balance correction image data; a second correcting unit that corrects the data on the strobe light-emission image using a second white balance correction value corresponding to strobe light, and generates second white balance correction image data; an acquiring unit that acquires distance information indicating a distance from an imaging unit, of each object included in the strobe light-emission image; a calculating unit that calculates a ratio of a component of the strobe light for each region of the strobe light-emission image, based on distribution characteristics of the strobe light and the distance information; and a combining unit that combines the first white balance correction image data and the second white balance correction image data for each region using a combining ratio according to the component ratio.
