Abstract
An imaging device is provided that includes an imaging processor, a distance information detector, an outline-component maximum image detector, and a distance information correcting processor. The imaging processor captures a plurality of secondary images of the same object at different lens positions. The distance information detector detects distance information of the objects captured in each area of an image based on the sum of outline components in each of the areas in each of the secondary images. The outline-component maximum image detector calculates the sum of outline components for each of the secondary images and detects an image with the maximum sum. The distance information correcting processor replaces distance information of a target area, where the sum of outline components is less than a threshold value, with distance information of the image with the maximum sum.
