Abstract

An image capturing device that can detect color moiré includes an optical lens (5); an image capturing element (20) having a light receiving face on which is focused an image of an object using the optical lens (5), an image signal output from the image capturing element being generated as image data and stored; a contrast data computing means (29) to compute contrast data based on the image data; a color data computing means (29) to compute color data based on the image data; a first lens position determining means (28) to determine a first lens position of the optical lens based on the contrast data, with the first lens position focusing an object image onto the light receiving face; a second lens position determining means (28) to determine a second lens position of the optical lens where the color data peaks based on the color data; and a determining means (28) to compute a difference between the first lens position and the second lens position and compare the difference and a threshold set in advance, wherein the determining means (28) determines that color moiré occurs when the difference is smaller than the threshold.
