IMAGE PROCESSING DEVICE, IMAGING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

Provided are an image processing device, an imaging device, an image processing method, a program, and a recording medium that perform white balance bracketing according to image characteristics. An image processing unit 31 acquires a white balance gain which is applied to original image data in order to obtain a base image and a bracket image. The image processing unit 31 includes a color distribution acquisition unit 46, a first gain acquisition unit 41, and a second gain acquisition unit 42. The color distribution acquisition unit 46 acquires color distribution information of input image data. The first gain acquisition unit 41 acquires a base image white balance gain for obtaining the base image. The second gain acquisition unit 42 acquires a bracket image white balance gain for obtaining the bracket image on the basis of the color distribution information and the base image white balance gain.

主权项

1. An image processing device that acquires a white balance gain which is applied to original image data in order to obtain a base image and a bracket image, comprising:
a color distribution acquisition unit that acquires color distribution information of input image data; a first gain acquisition unit that acquires a base image white balance gain for obtaining the base image; and a second gain acquisition unit that acquires a bracket image white balance gain for obtaining the bracket image on the basis of the color distribution information and the base image white balance gain, wherein the second gain acquisition unit determines a bracket direction in a color space on the basis of the color distribution information and acquires the bracket image white balance gain on the basis of the base image white balance gain and the bracket direction.
