Abstract
A clustering processing unit sets representative data to be used in first clustering, for each of temporally continuous images, and repeats clustering of pixels based on the representative data. A representative data updating unit updates the representative data whenever clustering is repeated. As the representative data to be used in first clustering of each image, an initial value or representative data used in last clustering of an immediately preceding image is set based on predetermined input information. An example of the predetermined input information is operation information for an image capturing unit for capturing an image. If a dead cluster predictively forms due to an image change, the initial value is set as the representative data. This makes it possible to restrict accumulation of dead clusters, and suppress the decrease in segmentation accuracy.
