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.

Abstract: Provided is a dental image acquisition apparatus that allows for acquisition of images in a plurality of imaging directions with a single captured image. The dental image acquisition apparatus includes an oral cavity insertion section and an image acquisition section. The oral cavity insertion section is inserted into an oral cavity. The image acquisition section has a light source. The oral cavity insertion section has an imaging unit that includes an imaging section and a light reflection section. The light reflection section is placed at a position opposed to the imaging section via an imaging target. Also, the dental image acquisition apparatus can further include an image processing section and an image display section. The image processing section calculates three-dimensional coordinates of the imaging target on the basis of the image acquired by the image acquisition section. The image display section displays a three-dimensional image created on the basis of the three-dimensional coordinates calculated by the image processing section.

Abstract: The present technology provides a speckle imaging device including: an irradiation condition setting unit that sets an irradiation condition for coherent light with which an imaging object is irradiated; an imaging unit that captures scattered light obtained from the imaging object irradiated with the coherent light; an image generation unit that generates a speckle-enhanced image from a captured image captured by the imaging unit; and a leveling processing unit that generates a leveled speckle image from speckle-enhanced images corresponding to two or more different irradiation conditions.

Abstract: Provided is a highly accurate imaging technology that utilizes the speckle interference. The present technology provides a speckle imaging device including: an irradiation condition setting unit that sets an irradiation condition for coherent light with which an imaging object is irradiated; an imaging unit that captures scattered light obtained from the imaging object irradiated with the coherent light; an image generation unit that generates a speckle-enhanced image from a captured image captured by the imaging unit; and a leveling processing unit that generates a leveled speckle image from speckle-enhanced images corresponding to two or more different irradiation conditions.
