Abstract
To provide an image analyzing technology capable of obtaining an image with less shading and with enough speckle contrast. An imaging apparatus includes: a light source that irradiates an imaging object with coherent light with a first irradiation condition and a second irradiation condition; a speckle imaging unit that captures a first speckle image obtained from scattered light of the imaging object irradiate at the first irradiation condition, and a second speckle image obtained from scattered light of the imaging object irradiate at the second irradiation condition; and an information processing unit that separates speckle images at boundaries of average luminance difference formed in the first speckle image and the second speckle image, connecting the separaged speckle images at the boundaries, and analyzes the combined speckle combined image.
