Document Type and Number:
WIPO Patent Application WO/2020/255715
Kind Code:
A1
Abstract:
Provided are an image processing device, imaging device, image processing method, and an image processing program such that different color correction is carried out among frames of a moving picture in accordance with fluctuations in a light source. The image processing device is provided with: a moving picture acquisition unit (302) for acquiring moving picture data; a frame identifying unit (310) for identifying a reference frame and a correction frame from among a plurality of frames constituting the moving picture data; a first image area determination unit (320) for determining image areas to be used for calculating an intra-frame first correction coefficient, wherein a first reference image area is determined from the reference frame and a first correction image area corresponding to the first reference image area is determined from the correction frame; a first color signal acquisition unit (330) for acquiring a first reference color signal from color image data of the first reference image area and a first correction color signal from color image data of the first correction image area; and a first correction coefficient calculation unit (340) for calculating a first correction coefficient for matching the first correction color signal to the first reference color signal.
