Abstract

The process captures a plurality of images under a light source whose luminance varies over time, such as a fluorescent lamp, under such an imaging condition that a plurality of images that are different from one another in terms of light source conditions can be captured (S11). The process detects a temporal luminance variation from the plurality of captured images (S12), estimates a shadow area by using the temporal luminance variation (S13), and performs an image process such as a process of synthesizing a linearized image or an image segmentation based on optical characteristics (S14).

Dependent claims

An image processing method performed by a processor, comprising:

an imaging step of imaging a same object a plurality of times by means of an imaging device under a light source whose luminance varies over time under such an imaging condition that a plurality of images that are different from one another in terms of light source conditions can be imaged;
and
an image processing step of performing an image process by using a plurality of images imaged in the imaging step,
wherein the image processing step includes:
a step of detecting a temporal luminance variation from the plurality of images;
a step of estimating a shadow area in the plurality of images by using the detected temporal luminance variation;
and
a step of performing an image segmentation based on optical characteristics by using information of the estimated shadow area and the plurality of images.
